 Instructions for use:
 Connect the power supply and equipment, the measuring temperature is displayed, 
press the "SET" button, press " + or - " to set the desired temperature (long press " + or - " to quickly increase or decrease), 
 press "SET" to confirm the setting and return, controller automatically performs the relay ON/OFF. 
 the thermostat output is 10A relay, meet a variety of high-power loads. LED Indicator: LED off indicates the relay off; Lighting, indicates the relay is closed. 
 Digital LED Tubes: "LL" indicates sensor open, "HH" indicates overrange, the relay will be forcibly disconnected; "---" indicates high temperature alarm 
 Long press the "SET" button to enter the main menu settings, 
 press " + or - " to switching between P0-P6,
 then long press "SET" or 10 seconds without keystrokes to confirm the setting and return.

 Package Included:
 2*W1209 12V DC Digital Temperature Controller Board
100% complete machine patch, wave soldering, stable performance, good consistency.
Embedded CPU chip (MCU), more intelligent, lower power consumption.
Automatic power set memory (MCU built-in EEPROM memory unit).
Control accuracy of 0.1 degrees Celsius. Have been tested for stability, consistency and reliability.
Tips: - long press set to get menu, starts at P0 - press +/- to get next P-parameter - press set to choose that parameter - press +/- to select the value you want for that parameter - press set to accept it - long press +/- = reset to default - power-out does reset to default - default temp set is 34.5C
