TROVIS 5724-3 Electric Actuator with Process Controller (without fail-safe action)
TROVIS 5725-3 Electric Actuator with Process Controller (with fail-safe action)
for domestic hot water heating

Application
Electric actuators with process controller for heating, ventilation and air-conditioning systems

The electric actuators with process controller can be used for
DHW heating in instantaneous heating systems for small to
medium-sized buildings and for fixed set point control circuits
in mechanical engineering applications.
Special features
The TROVIS 5724-3 and TROVIS 5725-3 Electric Actuatorswith Process Controller are a combination of an electric actuator and an integrated digital controller with two PID controlmodules. They are especially suitable for attachment toSAMSON Types 3213, 3214, 3260, 3222 and 3226 Valves.
A special version of Type 3222 (DN 15) and Type 3222 N(DN 15) with a special plug design is available for small
installations (apartment or house). As a result, even small
tapping amounts can be controlled.
The TROVIS 5724-3 Actuator is without fail-safe action andTROVIS 5725-3 has fail-safe action. The TROVIS 5724-3 hasa manual override to manually move the valve in de-energized state.
• TROVIS 5724-3 with manual override (handwheel)• Control using two different set points, e.g. DHW temperature and DHW temperature for thermal disinfection.

Fig. 1: TROVIS 5725-3 Electric Actuator with Process Controller• Manual setting possible at the set point potentiometer orusing the TROVIS-VIEW software• Function to maintain water temperature constant, preventing the heat exchanger from cooling down between tapping• Pump output to control a circulation pump can alternatively be used as a fault alarm output or to register tapping.
• Reversible direction of action– Globe valve opens when the actuator stem retracts(increasing/increasing)– Three-way mixing valve mixes/diverts the flow(s) when
the actuator stem extends (increasing/decreasing)• Limit value monitoring:– The valve is closed by the actuator when the maximum
adjustable limit is exceeded– The frost protection function is started when the temperature falls below the minimum adjustable limit• Configuration, parameterization, diagnostic function andonline connection for monitoring using the TROVIS-VIEW
software– Direct data transmission using a connecting cable(direct connection to computer)– Data transmission over a memory pen

–• Testing according to DIN EN 14597–The TROVIS 5725-3 Electric Actuator with Process
Controller with fail-safe action "actuator stem extends"
is tested by the German technical surveillance association TÜV according to DIN EN 14597 in combination
with different SAMSON valves. Such actuators have atest mark on their nameplate.

The electric actuator without fail-safe action has a
handwheel (2) used to manually position the valve (onlywhen the actuator is disconnected from the power supply).
Travel and direction of action can be read off the travelindication scale (9).

The registration number is available on request.

The electric actuator with process controller with fail-safe
action largely corresponds to the TROVIS 5724-3.
However, it contains a spring assembly (8) and anelectromagnet which in de-energized state move theconnected valve to the appropriate fail-safe position. Only
the version with fail-safe action "actuator stem extends" isavailable.

–Options• Faster motor–TROVIS 5724-3

Version with double speed

Design and principle of operation
The electric actuator with process controller consists of a digital controller that is integrated into the electric actuator housing. The digital controller is connected to a temperature sensor
on the input side which can be optionally upgraded by a flowrate sensor or a flow switch.
The set point of the digital controller can be set manually orusing the TROVIS-VIEW software.
The electric actuator with process controller contains a reversible synchronous motor and a maintenance-free gear. The
synchronous motor is switched off by torque-dependent
switches in the end positions or in case of overload.
The output signal of the integrated digital controller acts overthe positioner on the synchronous motor of the actuator. The
force of the motor is transmitted to the actuator stem (3) via
gear and crank disk. When the actuator stem extends, it
presses on the plug stem (10) of the valve. When the actuator
stem retracts (force-locking attachment), the plug stem follows
the movement of the actuator stem as a result of the return
spring in the valve. Actuator and valve are connected by thecoupling nut (4).

A handwheel (2) is not fitted. After the actuator isswitched off and the cover (1.1) removed, manual
override with an Allen key is possible. As soon as theAllen key is released, the actuator immediately moves
back to its original position.
–Version with faster motor
The Types 5724-313/-323/-333 and Types 5825313/-323/-333 are equipped with a faster motor in a
housing attached to the back of the actuator.

Electrical equipment–

Alternatively, a current signal can be used for mechanical engineering applications.
A binary input is used to switch between two internal
set points or, alternatively, can be used to deactivate
the function to maintain the heat exchanger at aconstant temperature.

Inputs
The integrated digital controller must be connected toa temperature sensor on the input side, which can be
optionally upgraded by a water flow sensor or a flowswitch.

When the actuator stem retracts (form-fit attachment), the plug
stem is connected to the actuator stem and follows its movement.

OutputA circulation pump can be control with the 230 V
switching output (see Table 1). The switching output
can be configured as either a pump output (circulation
pump for the DHW circuit or heating circuit), a fault
alarm output or an output to indicate when hot wateris tapped.

1Setting
The set point of the digital controller is set to 60 °C and asecond set point is set to 70 °C. They can be changed inTROVIS-VIEW using a connecting cable connected to theRS-232 interface (serial interface) on the actuator or using amemory pen.
The set point can also be adjusted at the set point potentiometer on the device.
The controlled variable, control behavior and other parameters can be changed in this way.

Option to improve control accuracy in small installations

0...90°The use of the Type 5207-0060 Pt 1000 Sensor isrecommended in conjunction with a sensor pocket to provide
optimal positioning of the temperature sensor at the heatexchanger.
In addition, a water flow sensor or a flow switch can beconnected to quickly recognize when hot water is being
tapped or to improve the control accuracy even further.
A hot water circulation pipe improves the control accuracy
considerably.

Mounting

Mounting position
The control valve can be installed in the pipeline in any desired position. However, a suspended mounting position of theactuator is not permissible (see Fig. 3).

6To retract the actuator stem of TROVIS 5725-3, remove thefront housing cover and retract and retain the actuator stemby turning the actuating shaft counterclockwise using a 4 mm
Allen key. Hold the actuator stem in this position, while tightening the coupling nut.

Before mounting the actuator on the valve, retract the actuator
stem.
