Operation instructions When the controller is working normally, press and hold the power button for more than 3 seconds to turn off the controller. When the controller is off, press and hold the power button for more than 3 seconds to turn on the controller. When the controller is normal, the digital tube displays the current temperature measurement value, and automatically recognizes and switches the cooling and heating working mode. When the measured temperature is greater than or equal to the set value of the temperature + the set value of the temperature difference, it enters the cooling state, the Cool indicator light is on, and the normally open contact of the refrigeration relay is closed: the Cool indicator flashes, indicating that the refrigeration equipment is in the compressor delay protection state; when the measured temperature ≤ For the temperature setting value, the Cool indicator light is off, and the normally open contact of the refrigeration relay is disconnected. When the measured temperature is less than or equal to the temperature setting value-the temperature difference setting value, it enters the heating state, the Heat indicator light is on, and the heating relay normally open contact is closed; when the measured temperature ≥ the temperature setting value, the Heat indicator and the heating relay normally open contact are broken Open.
