How To Use

Connect the power supply and equipment to power the controller. At this time, the display shows the measured temperature. Press the SET button once, the temperature on the display flashes, and press +-to set the desired temperature (press +-to quickly rise and fall). After completion, press SET to confirm and return. At this time, the controller will automatically switch on and off the relay according to the setting! The thermostat output is a 20A relay, which can meet various high-power loads. Connect the control circuit to power the thermostat. At this time, the display shows the ambient temperature.

Fourth, indicator light, digital tube and buzzer status

Indicator light: flashing means the cooling or heating start delay, constant light means the relay is closed.

Digital tube: display LL is the sensor is open, please connect the sensor according to the instructions; display HH is out of the measuring range, the thermostat will forcibly disconnect the relay; Display---high temperature alarm
