    in reply to: Temperature Controller #3673

    Hello Adair,
    Thank you for writing in.
    This problem is related to the working mode you set.
    You can try to set the working mode again.
    Long press the SET button for about 5 seconds, when the screen display “PO” then press SET button again, when the screen displays “C”, you can use “+” or “-” button to chose the working mode. “H” is for heating mode and “C” is for cooling mode.
    In cooling mode, when the measured value ≥ set value, the cooling relay will be connected and the cooler will be activated. When the measured value ≤ set value, the cooling relay will be disconnected and the cooler will be turned off.
    In heating mode, when the measured value ≤ set value, the heating relay will be connected and the heater will be activated. When the measured value ≥ set value, the heating relay will be disconnected and the heater will be turned off.
    Hope this can help you.
    Best regards
