Features 1、Simple Operation: Very easy to operate, displaying PV and SV values upon power on. Press the SET button once to start modifying the SV value. You can start using the thermostat in one step. 2、Two Control Methods: Supports both on off control and PID control, and the latter doesn't have self tuning function. 3、For Heating and Cooling: When the temperature is lower than the set value, turn on the output to start heating. When the temperature is above the set value, turn on the output to start cooling. 4、Alarm Function: Over temperature and low temperature alarms, under voltage alarms, and NTC disconnection alarms. With one alarm signal output. 5、Other Functions: The temperature controller also has timing mode function and power saving mode function, which will largely simplify the operation.
