•

Apply all safety regulations.

•

Do not apply force or pressure on components during the installation procedure.

•

Refer to your supervisor if problems occur during installation procedure.

CAUTION
This unit must be installed inside, in a location protected from solar radiationand direct rain.

2.1

Basic Requirements for On-Site Preparation•

Verify power source between 115 VAC or 220 VAC ± 10%•

On the unit is a silver label stating the unit’s voltage (110 or 230 VAC). Verify thatyour unit supports the voltage supplied in your country.

•

Verify grounding connection < 10Ω•

Environment temperature between -10° C / 14° F to +60° C / 140° F•

Verify protection from damaging climate conditions

2.2 Frequency Inverters•

Frequency inverters can cause severe electrical and electromagnetic interference.
Therefore, when employing a frequency inverter, it is critical that you carefully
follow the manufacturer's installation instructions.

•

In particular verify:o that the cable shielding between the inverter and any motor meets industry
standards

3.3 Firmware UpgradeThis section details the software upgrade procedure, starting from determining which SD
card is compatible.
The Bootloader application enables updating the system firmware. The application is menu
based and simple to use and enables updating the firmware from an SD card. Due tochanges made by SD card manufacturers in newer cards, there is a compatibility issue
between these cards and the ARM CPU boot section software (the software used whenupgrading the controller firmware). The card is found inside the ARM CPU.
Because of this incompatibility, the procedure suspends itself and an error message
appears: SD CARD NOT FOUND. (In certain cases, the process can simply suspend itself
with no message given.)
CAUTIONRMA.

If the upgrade process fails, contact Munters technical support regarding an

NOTE Verify that the card is in place before starting.

•Green Field ECO supports up to 4 GB SD cards.

© Munters AB, 202013

3.3.1 PRELIMINARY INFORMATION•

Munters strongly recommends having a spare CPU on site, in case the upgrade
fails.

•

Before upgrading, store the controller’s setting on a data plug (refer to Write toData Plug).

•

After upgrading, upload the controller’s setting from a data plug (refer to Readfrom Data Plug).

•

While upgrading the firmware, a qualified Munters technician:o must be on-site.
omust verify that the process is complete; verification includes checking allaccessories connected to the controller.
•In the event that the controller sends a message regarding incomplete
information, the technician must enter the missing information
manually and verify that the information is correct while in the field.

By default, in all sessions the controller returns to automatic mode. The technician
must verify that there are no manual mode devices in the field.

CAUTIONAny upgrade that is not performed in accordiance with these guidelines
could result in unforseen malfunctions in the field equipment. Munters will not takeresponsibility for these issues.

3.3.2 FIRMWARE – SD CARD COMPATIBILITY

Device Delay Configuration

The Device Delay Configuration screen enables defining the startup and shutdown order ofthe irrigation process.

© Munters AB, 202035•On (mm:ss): On is the definition of the startup order. The set times are taken fromprocedure startup. The device with the shortest time will be started first andshifted to procedure startup. Therefore it is recommended that the device that is
to be started first be set as 00:00 (automatically changes to --:--).

•Off (mm:ss): Off is the definition of the shutdown order of the irrigation process.
The set times are taken from procedure shutdown. The device with the shortest
time will be stopped first and shifted to procedure shutdown. Therefore it isrecommended that the device that is to be stopped first be set as 00:00(automatically changes to --:--).

7.2 Pump Station Configuration
The Green Field ECO can include up to six pumps. Each valve (irrigation, cooling, or misting)can be connected to one of the pumps or to the pump station. The pump station is a groupof pumps (out of the six possible pumps) that will be started in accordance with therequired flow. The Pump Station configuration screen allows you to define which pumps
are part of the station, the capacity of the various pumps and their startup and shutdown
delays.

The Green Field ECO automatically calculates the expected flow and determines whichpump (or pumps) should be started (see Valve Configuration for additional information
regarding flow calculation). The Green Field ECO will start the minimal number of pumps
required to supply the calculated flow rate.
If several pumps should be started, the Green Field ECO starts from the largest to thesmallest and will turn them off from the smallest to the largest.
•

Pump No.: Pump number.

•

Capacity: Define pump capacity in m3 or gallon. This will be the maximum pumpcapacity, above which the Green Field ECO will turn on another pump (ifavailable).

•

Stability (mm:ss): Define stability time. Stability time is the startup time requiredfor current pump before next pump can be started up. Stability time is usuallyused to prevent voltage drop down and water hammer (see Pump Startup Order
schema).

•Off Delay (mm:ss): Define off delay. Off delay will be the delay time for current
pump to stop after last pump has stopped. This delay is usually used to prevent
water hammer (see Pump Shutdown Order schema).

•

Station (Yes/No): Define whether the pump is part of the pump station.

7.3 Valve Configuration
Valve configuration allows you to configure devices such as pumps, main valves, anddrainage measurement of valves.

•

Valve No.: Indication of the valve number.

•

Pump: Define which pump or pump station should be started when irrigating thisvalve. When choosing Station, the Green Field ECO will choose which and how
many pumps should be started to supply the required (calculated) flow. See Pump
Station Configuration on page 38 for more information).

•

Main Valve: Define which main valve should be opened when starting each valve.

•

Water Meter: Configure a water meter to each valve. This option is only possible
when the flow calculation (water meter type) is Standard.

NOTE Make sure that you define an operative water meter. There is no protection against
defining a water meter that isn’t properly defined in the system.
Note that when operating using Water Source (refer to Water Meter, page 40) a valve is
not configured to a specific water meter. In this case, all water meters set in the system are
relevant for each irrigation; their pulses are calculated for the flow rate. Therefore theWater Meter column is irrelevant in the Valve Configuration table.
NOTE Make sure that you define an operative water meter. There is no protection against
defining a water meter that isn’t properly defined in the system.
NOTE When using more than one water meter only start two valves that are configured
to the same water meter; the Green Field ECO uses only the water meter connected to
the leading valve and does not sum the flow from the rest of the water meters. Dosing
in this manner can create unexpected alarms and malfunctions!
•

Drain Meter: Define which drain meter this valve is connected to.

•Drain Type: Define drainage type:o Total: Drainage is collected from the complete valve area.
oSample: Drainage is collected from a representing part of the valve area.

Note that it is possible to set several valves to the same drain meter when working by'Total'. The system does not allow operating several valves on the same meter when
operating by 'Sample'.
•

Sample %: When using sample drainage measurement it is required to define theratio of the sample area to the complete valve area.

© Munters AB, 202039

7.4 Valve Flow Rate•

Nominal: Define nominal valve flow rate (m3/h or gallon/min). The Green Field
ECO uses the set nominal flow rate for calculating the ratio between valves whenstarting a few valves together, the boundaries for alarms, the total flow rate forcalculating how many pumps to start, etc. Therefore it is recommended to try andset the nominal flow rate as close as possible to the actual flow rate.

•

Minimum: Minimum valve flow rate, under which the system will generate a low
flow alarm. When changing the Nominal flow rate this setting is automatically set
to 25% under the nominal flow and can be manually changed.

•

Maximum: Maximum valve flow rate, above which the system will generate a highflow alarm. When changing the nominal flow rate this setting is automatically set
to 25% above the nominal flow and can be manually changed.

NOTE When starting several valves simultaneously the system will sum their nominal,
minimal and maximal flow rates. An alarm will be generated only if the measured flowrate is lower than the total minimum, or higher than the total maximum.
NOTE When starting several valves simultaneously, the quantities between them will be
divided based on the ratio of their nominal flow.

7.5 Water Meter•

Ratio: Set volume per pulse of each water meter or auxiliary meter.

•

Type: Define type of flow calculation:o Standard: In this function valves which are operated in a group should beconnected to the same water meter.

© Munters AB, 202040

NOTE If a few valves configured to different water meters will be started simultaneously,
the Green Field ECO uses the flow measured by the water meter connected to theleading valve.
oWater source: The Green Field ECO will sum or deduct flow measured
simultaneously from a few water meters. When choosing this function an
additional column called ”SUM” will appear, this column enables to define
which water meters should be summed and which deducted from the total
measured flow.

NOTE Flow calculation type is a general definition for all water meters, therefore whenchanging type of water meter for one of the water meters the type will be changed for
all water meters.
NOTE When setting flow calculation (water meter type) to Water source it is not possible
to configure valves to water meters.
•

Sum: Define whether flow measured by each water meter should be added to thetotal measured flow or deducted:
o “+” Flow measured by this water meter will be added to the total measured
flow.
o “–” Flow measured by this water meter will be deducted from the total
measured flow.

NOTE Since flow cannot be negative, if the controller measures negative flow it will show
zero.
NOTE If all valves are set to "–" the system ignores the measured flow and will use thenominal flow (based on the nominal flow).

o Time (cc/sec): Define whether the calculated flow rate of the dosing channel
is in CC (gallons) of fertilizer per second.
o Time (Liter/min): Define whether the calculated flow rate of the dosing
channel is in liters (gallons) per minute.
o Time (Liter/Hour): Define whether the calculated flow rate of the dosing
channel is in liters (gallons) per Hour.

•

Ratio
o Method is Time: Define calculated flow rate, this will be the flow rate of thechannel when completely open.
o Method is Liter/Pulse: Define the volume per pulse.

•

React: Set the required use of the channel:o EC: The channel is used to increase measured EC, meaning it will be opened
more when the measured EC is lower than the set EC.
o pH: The channel is used to decrease measured pH, meaning it will be opened
more when the measured pH is higher than the set pH.
o Passive: The channel does not respond to changes in measured EC/pH,
meaning it will be opened as set in the dosing program regardless of the
EC/pH values.
o Alkali: The channel is used to increase measured pH, meaning it will be
opened more when the measured pH is lower than the set pH.
© Munters AB, 2020

42

NOTE If EC/pH control is off, or the channel is used for proportional injection only (forexample in order to inject chemicals) set reaction to passive.
•

High %: set an injection percentage limit. This percentage will limit the deviationfrom set dosing recipe when Green Field ECO is injecting more than specified inorder to try and reach the target EC/pH values.

•

Low %: set an injection percentage limit. This percentage will limit the deviationfrom set dosing recipe when Green Field ECO is injecting less than defined in order
to try and reach the target EC/pH values.

•

V/P(L/G): This parameter is disabled when operating by Liter/Pulse. Define thevolume per pulse of the dosing meter (liters or gallons). Only required when using
a dosing meter for measurement and alarm purposes. When using a dosing meterfor control purposes the volume per pulse of the dosing meter should be definedon the Ratio column. The letter between the brackets indicates whether thevolume units are in Liter or Gallon.

7.7 Dosing Configuration•

EC Control: Define whether EC control should be operative.

•

pH Control: Define whether pH control should be operative.

•

EC Alarms: Define whether EC related alarms are operative. When EC control is
set to ‘Yes’, EC Alarms are automatically set to ‘Yes’ and cannot be changed.

•

pH Alarms: Define whether pH related alarms are operative. When pH control is
set to ‘Yes’ pH Alarms are automatically set to ‘Yes’ and cannot be changed.

•

Minimum On Time (sec): Define the minimum time the dosing regulator can be
open. This feature is used to protect the regulator from being excessively turnedon and off. The minimum allowed on time is 0.4 seconds.

•

Minimum Off Time: Define the minimum time the dosing regulator can be off. Thisfeature is used to protect the regulator from being excessively turned on and off.
The minimum off time allowed is 0.4 seconds.

•

EC Coarse Tuning (0-10): EC Coarse Tuning is used to adjust the speed andstrength of the EC control. A higher value will result in faster correction but mightlead to over shooting (see Appendix 1 – General > EC/pH correction adjustment for
further information).

•

EC Fine Tuning (0-10): EC Fine Tuning is used to fine tune the EC control shooting(see Green Field ECO Irrigation > Part 2 > General > EC/pH correction adjustment
for further information).

pH Fine Tuning (0-10): pH Fine Tuning is used to fine tune pH control shooting(see Green Field ECO Irrigation > Part 2 > General > EC/pH correction adjustment
for further information).

•Control Cycle (sec): Define the control cycle for EC/pH control. This should be thetime it takes the system since it injected fertilizer/acid until the change inrecognized by the system.

•

EC/pH Averaging (0-Low, 20-High): Averaging factor for EC/pH measurement.
EC/pH averaging should be used to enable correction when injection is nothomogenous.

•

Dosing Booster Off Delay (mm:ss): Define the time that the dosing booster shouldbe left on after dosing has ended. This time is usually used to circulate the acidand nutrients in order to prevent high concentrations in the area of the venturies
and dosing booster when the system is idle.

•

Dosing by QTY. Method:o Bulk: All channels set to QTY (quantity) dosing method will inject the set
quantity in one bulk, starting after water before quantity/time has elapsed.
o Spread Out: The set dosing quantity of all channels set to QTY (quantity)
dosing method will be spread throughout the irrigation.

7.8 Drainage Configuration•

Ratio: Define volume per pulse of the drainage meters (liter/pulse or
gallon/pulse).

•

On Delay: Define how long a valve, which is configured to this drainage
measurement, should be open before the measured drainage is related to thisvalve. All drainage measured before this time has elapsed (although the valve isopen) will still be related to the previously opened valve that was configured tothis drainage sump.

•

Off Delay: Define how long after irrigation has finished, the measured drainage
should still be related to the previous irrigation. This value is used to “tell” thecontroller when to stop relating drainage to the previous irrigation and write it to
all relevant history tables.

9.1 Irrigation
The Irrigation Program screen includes all the settings for configuring automatic irrigation
start. It depends heavily on the Water Run Time and dosing program screens; therefore it isrecommended to configure these screens before irrigation takes place.
The Green Field ECO consists of 15 irrigation programs.

•

Program: Select a program by entering the program number and confirm bypressing.

•

Priority: Priority determines the order in which programs will take place. If start
time is the same, higher priority programs come first. Higher priority programs do
not stop currently operative programs.
If start time and priority are the same, irrigation programs with a lower number are
executed first. Priority ranges are between 0 and 15, 15 being the highest (SeeGreen Field ECO Irrigation – Part 2 > Priority specifications for further information).

•

Const / Daily / Cond. / Rad Sum / VPD Sum:o CONST.: Increase or decrease the amount of water for all valves included inthis program. 0% means the quantities will be as specified in the Water Run
Time program, 100% will be twice the amount and –50% will be half theamount specified in the Water Run Time Program. To decrease enter therequired percentage of change, press the +/- key and confirm with the
key. The percentage of change is active until you specify otherwise.
o

Select ‘blank’ and press
to set the valve to operate alone, or ‘+’ (plus)
to operate together with the next valve. Several valves can be set to work
together, as a group. A valve set (group) will have the same Run Time program
and the same dosing program. Each irrigation program can include a maximumof 100 valves (columns) in any required order (all of them together, one after
the other, a few groups-max. 100 groups, etc.). The same valve can be entered
several times with different settings.
•

Run Time #: attach a Run Time Program to a valve or a group of valves. Whensetting valves to work individually, a Run Time Program should be set for eachvalve. When setting a few valves to work together (“+” mark between them) a Run
Time Program should only be set for the first valve, the rest of the valves will
follow this setting.

NOTE The quantity set in the Run Time Program will be the quantity given for all valves
set to operate together, not per valve (for further specifications of the Run Time
Program see Water Run Time, page 58).
•

Dosing Program: Attach a Dosing Program to a valve or a group of valves. Whensetting valves to work individually, a Dosing Program should be set for each valve.
When setting a few valves to work together (with “+” mark between them) a
Dosing Program should only be set for the first valve, the rest of the valves will
follow this setting.

•Day (xx/xx): Allows defining whether the program should irrigate water only, doseor be turned off on different days.

Dosing Program•

Dosing Injection Methods

9.4.1 DOSING PROGRAM•

Program: Select a program by entering the program number and confirm bypressing.
INJECTION PER DOSING CHANNEL•

Dosing channel number: 1 to 8.

•

Reaction: A read only line indicating the purpose of the channel.
o EC: the channel is used to increase measured EC, meaning it will be opened
more when the measured EC is lower than the set EC.
o pH: the channel is used to decrease measured pH, meaning it will be opened
more when the measured pH is higher than the set pH.
o Passive: the channel does not respond to changes in measured EC/pH,
meaning it will be opened as set in the Dosing program regardless of the
EC/pH values.
o Alkali: the channel is used to increase measured pH, meaning it will be
opened more when the measured pH is lower than the set pH.

•

Quantity / Time: Set the Quantity / Time to be injected for each dosing channel.
The injection method (proportional, quantity, time, etc.) can be set separately foreach use of the channel (EC, pH, Passive).

•

Target EC: Set the required EC target value, only visible if EC control or EC alarms
are active, see table 1.3.

•

Target pH: Set the required pH target value, only visible if pH control or pH alarms
are active, see table 1.3.

•

Passive Dosing Method: Set the required injection method of the Passive dosing
channels (see Dosing injection method).

•

EC Dosing Method: Set the required injection method of the EC dosing channels(see Dosing injection method).

•

pH Dosing Method: Set the required injection method of the Acid and Alkali dosing
channels (see Dosing injection method).

9.4.2 DOSING INJECTION METHODS•

P.Qty (1/1000): Proportional quantity. Each dosing channel can be set to give a
different amount. The set amount is 1 part (Liter or Gallon) fertilizer/Acid per 1000
parts (m3/h or 1000 Gallons) of water.

For example:ooChannel 1 is set to 5.0 (liters or gallons).
Set water quantity is 3.5 (m3/h or 1000 gallons).

This setting actually means that 5.0 (liters or gallons) of fertilizer will be mixed
with each cubic meter (1000 gallons respectively) of water passing throughthe system.
The total quantity of fertilizer that will be given is 5.0 * 3.5 = 17.5 liters(Gallons).
•

P.Time (hh:mm): Proportional time. Each dosing channel is given the time tofertilize independently. The Green Field ECO divides this time equally within thegiven irrigation time (quantity) set in 1.2 WATER RUN TIME.

For example:ooDosing channel 1 is set to 00:10; Dosing channel 2 is set to 01:00.
Set irrigation time is 03:00 hours.

The Green Field ECO will proportionally divide the set fertigation time for eachdosing channel across the set irrigation time (quantity).
Dosing channel -1- will be on for a few pulses; their total time will be 10 min.
Dosing channel -2- will be on for a few pulses (not necessarily the sameamount). Their total time will be 60 min.
•Time. (hh:mm): Each dosing channel is given the time to fertigate. Dosing will bedone in one bulk that will start after water, before time/quantity has elapsed.

•

Qty. (Liters or Gallons): Quantity. Each dosing channel is given the amount to be
injected. Dosing will be done in one bulk or spread throughout the irrigation,
depending on settings in the screen 7.7 DOSING CONFIGURATION, line Dosing by
QTY. Method. Dosing will start after water, before time/quantity has elapsed.

Example: If the time between flushing is set to 01:00 it means that a flushing cycle© Munters AB, 202069

will be activated after 1 hour of irrigation (regardless of DP status).
If set to zero (--:--), flushing will only take place if triggered by a DP.
•

Flushing Time (mm:ss): Flushing time of each Filter (output).

•

Delay Between Filters (mm:ss): The delay time between flushing of one filter tothe next. This time is usually used to allow pressure buildup.

•

Delta Pressure (Digital): Define whether filter flushing can be triggered due todigital Delta Pressure (Yes / No).

•

Delay Delta Pressure (mm:ss): Define the time that the Delta Pressure (digital orvalue) must be active before a filter flushing cycle will be triggered. This time isusually used to prevent unnecessary flushes from taking place.

•

Delta Pressure Reiteration: Number of consecutive filter flushing cycles triggeredby the Delta Pressure that can take place without any breaks, before the Green
Field ECO will generate an alarm indicating that the Delta pressure sensor isdefective. The Green Field ECO will than ignore the Delta Pressure and willcontinue flushing according to the set Time Between Flushing only, until the alarmis reset.

•

Dwell Time Main Filter Valve (mm:ss): Define for how much time the main filter
valve must be on before the filter flushing cycle is started. This output is typicallyused to control a pressure-sustaining valve or to start a booster pump.

9.9 Cooling
The Cooling/Humidification program is used to keep the temperature below a set value
and/or the humidity above a set value. Each program can be set to maintain temperature or
humidity as its first priority.
Five Cooling programs are available with two periods in each program. The periods can be
defined to overlap, thus creating “dynamic” cooling or humidification.
Different temperature and humidity sensors can be connected to each program.
The Status can be defined as Cooling or Humidification, the aim of the status field is tohelp the user to understand the process that should take place by placing the related set
point first (i.e. above t° when the status is cooling OR bellow RH when the status is
Humidification)

to confirm.

Example:••Settings:
o Period 1 is set between 08:00 to 16:00. The cooling process should work
above temp. of 30oC and Below RH of 80%.
o Period 2 is set between 08:00 to 16:00. The cooling process should work
above temp. of 40oC and Below RH of 80%
o On time is fixed to 30 sec in both periods.
o

Off time is 3:00 minutes which relates to the lowest temperature setting(30°C)o

Off time is 1:00 minute which relates to the highest temperature setting(40°C)

Scenarios:o Time is 10:00, the measured temperature is 35oC and the measured relative
humidity is 65%, the cooling valve will be open for 30 seconds and close for
2:00 minutes in a continuous cycle.
o Time is 12:00, the measured temperature is 30oC and the measured relative
humidity is 65%, the cooling valve will be open for 30 seconds and close for
3:00 minutes in a continuous cycle.
o Time is 14:00, the measured temperature is 40oC and the measured relative
humidity is 50%, the cooling valve will be open for 30 seconds and close for
1:00 minutes in a continuous cycle.
o Time is 15:00, the measured temperature is 35oC and the measured relative
humidity is 85%, the cooling valve will not be open since the measured
relative humidity is above the maximum allowed (80%).

NOTE If more than one cooling valve is defined, the off time will take place after the lastvalve in the sequence (Cooling valve #2, in the above screen). Between the coolingvalves there is no delay and they are working in sequence, from the first valve on theleft side to the last one.

© Munters AB, 202071

NOTE If the time is relevant only for a certain period, only its settings will define
operation. If humidity is above the lowest value of the two periods, cooling will not takeplace.
•

From (hh:mm): Set the start time of the Cooling / Humidification program.

•To (hh:mm): Set the end time of the Cooling / Humidification program

NOTE The program will only be operational in the defined time window (between start“From” to end “To” times). Each program can be operational at different hours.
•

Above to / Below RH
o Above to (when status is cooling): Start cooling above this temperature.
Cooling will stop if the temperature drops below the internal dead-band of
0.5oC. For example if set to 30oC cooling will start when the temperature is
above 30oC and will stop when it drops below 29.5oC. °o Below RH (when status is humidification): Start humidification below thishumidity. Humidification will stop if the humidity goes above the internal
dead-band of 1%. For example, if set to 80% humidification will start when
the humidity is below 80% and will stop when it is above 81%.

•

Below RH / Above too Below RH (when status is cooling): Stop cooling above this humidity. Coolingwill be resumed when the humidity drops below the internal dead-band of
2%. For example, if set to 80% cooling will stop when the humidity is above
82% and will be resumed when the humidity drops below 80%.
o Above to (when status is humidification): Stop humidification when thetemperature is below this temperature. Humidification will be resumed when
the temperature goes above the internal dead-band of 0.5oC. For example, if
set to 25oC humidification will stop when the temperature drops below
24.5oC and will be resumed when it goes above 25oC.

•

On (hh:mm:ss): Define the On time of the Cooling valve. If On time is set to zero,
the Cooling valve will not be opened.

•

Off (hh:mm:ss): Define the Off time of the Cooling valve. If Off time is set to zero,
the Cooling valve will be constantly On.

•

Cool #: Assign cooling valves to this program. The assigned cooling valves will be
operated sequentially in groups. The number of groups (different cooling© Munters AB, 202072

programs) which can be operated simultaneously (maximum cooling parallel) is
defined in screen 6.2 SYSTEM SETUP.
•

Temp. Sens.: Assign Up to two temperature sensors for this program.

•

Hum. Sens.: Assign up to two humidity sensors to this program.

If there is a malfunction in one of the temperature sensors, a message will be displayed,
and that sensor will be taken out of the average temperature calculation. If all thetemperature sensors are out of order, the controller will operate according to the firstactive line. If you would like to operate the program by time only, set as follows:
Set Status to cooling or humidification (not important). Set the Above t°. and Below RH to'0'. Define the required On and Off times and the program will work accordingly within theset time frame.

9.10 Misting
The misting program is a time scheduler used to open/close a misting valve or any otherdevice that is operated sequentially. Up to 40 misting programs can be preset.
Note that there are a few steps that should be defined prior to this screen, see the Misting
Configuration Table on page 45.

•

Mist No.: Assign a mist valve to the program. It is possible to associate the same
misting valve with several programs.

•

Start (hh:mm): Set the start time of the Misting program. If start time is set to
00:00, it will automatically be changed to --:--, meaning the program is notoperational.

•

End (hh:mm): Set the end time of the Misting program. The Misting program will
only be operational in the defined time window (between Start to End times). Each
Misting program can be operational at different hours.

•

On: Define the On time of the misting valve. If On time is set to zero the MISTING
valve will not be opened.

•

Off: Define the Off time of the MISTING valve. If Off time is set to zero the
MISTING valve will be constantly On.

The table is sorted according to mist number as the first priority and start time as thesecond priority. The Mist No. will always appear in groups in an increasing order so that theorientation is quick and easy.
Each mist group has an inside start time sorting, so that a later start is moved to the end of
the group. If you delete a row (by zeroing the Mist .No.) it will be moved to the end of the© Munters AB, 202073

table and the rest of the rows will move one step up. Pressing the menu key does thissorting.
NOTE When misting is on all related devices (e.g. misting valve, main valve, and pump)
are operational. When misting is off, only the pump continues to operate

9.11 Water Heating

Water Heating operates according to temperature within a set time frame (between start“From Time” to end “To Time”) and can be used to increase irrigation water temperature or
prevent frost.
•

From Time (hh:mm): Set the start time of the water-heating program.

•

To Time (hh:mm): Set the end time of the water-heating program.

•

Water Temperature: Water heating will be activated when the temperature drops
below this value.

•

Difference: Dead-band for stopping water heating. When the water temperaturereaches the set Water Temperature + Difference, water heating will be stopped.

For Example: Water temperature is 25ºC and the difference is 2ºC. Water heating will
start when the temperature drops below 25ºc and will stop when it is 27o or above.
The Minimum difference is 0.3ºC and the default is 0.5ºC.
•

Temp. Sensor 1/2: Assign up to 2 temperature sensors. If you assign 2 sensors, theGreen Field ECO will operate according to their average.

station directly or through the network.
o Local: A weather station is connected to this controller; its data is used
locally only and should not be passed or received through the network.
o Slave: This controller receives weather station data through the network; thedata is collected by another Green Field ECO (or Greenhouse Climate), whichis connected directly to a weather station defined as Master. Sensors
connected directly to a slave controller will be used by it and will have ahigher priority than those transmitted by the master.
OPERATION MODE•

Automatic return to RO mode: Define if the controller will return automaticallyback to the Read Only mode after a certain period of time.

•

Return Period to Read Only mode: Set the amount of time for the controller toreturn automatically to the Read Only mode (mm:ss).

COMMUNICATION•

Controller Number: Select the controller number for communication. The
controller number in the controller and in the PC should match in order for the© Munters AB, 202080

communication to work. Each controller in the network must have a unique
number.
WATER SOURCE•

Flow Rate – Start From: Select whether the flow rate calculation in an irrigation
will begin either with the value Zero (which means that the flow rate will increase
according to pulses received), or a Nominal value calculated using all the active
valves in the irrigation. The calculation method is important primarily for dosing
and EC/pH control. When using a controller which operates with relatively slow
pulses, it is recommended to choose the Nominal flow rate option due toinaccurate flow calculation in the first stage of the irrigation. When operating withslow pulses and starting with a Zero value, it will take a long time for the controller
to reach its' actual flow rate value. When operating by fast pulses, choose either
Zero or Nominal.

•

Calculated Flow Delay: This parameter is relevant only when Nominal is being
selected in the previous parameter. This parameter defines the time the controller
uses its' nominal flow rate value before switching to the calculated one. In thisperiod LOW FLOW and HIGH FLOW alarms will not be detected.

NOTE To enable this parameter, set the Water Meter to Water Source. Refer to Water
Meter, page 40.

Warranty and technical assistance
Munters products are designed and built to provide reliable and satisfactory performancebut cannot be guaranteed free of faults; although they are reliable products they candevelop unforeseenable defects and the user must take this into account and arrange
adequate emergency or alarm systems if failure to operate could cause damage to thearticles for which the Munters plant was required: if this is not done, the user is fully
