Product Function

After power failure, press and hold the+- keys simultaneously to power on and display 888, which will restore the factory settings.

Example of Heating Mode

Example: Control the heating of the radiator to stop at 60 degrees, and start again at 50 degrees after stopping.

It needs to be set to heating mode with a temperature difference of 10 degrees, and should be set as follows:

1. When the temperature is displayed normally, press SET once to flash the temperature, and set the stop temperature value to 60

2. Press and hold SET to display P0 and set the working mode to H

3. Set the P1 hysteresis value to 10

Example of cooling mode

Example: Control the refrigerator to cool down to -5 ℃ and stop, then start cooling again when the temperature rises to 0 ℃

It needs to be set to cooling mode with a temperature difference of 5 degrees, and should be set as follows:

1. When the temperature is displayed normally, press SET to flash the temperature and set the stop temperature value to -5 ℃

2. Press and hold SET to display P0 and set the working mode to C

3. Set the P1 hysteresis value to 5

Product Attention

How to set the stop temperature?

The temperature controller displays real-time temperature when powered on. Press the SET button once and the screen will flash. Press the up and down buttons to set the stop temperature

How to enter the internal settings?

Press and hold the SET button for 5 seconds

PO: Working mode

When using the thermostat for the first time, the mode must be set. If it is used for heating (low temperature start, high temperature stop), it should be set to H; if it is used for cooling (high temperature start, low temperature stop), it should be set to C

P1: Return difference setting

Long press the SET button to enter the internal settings, select P1, and then press the SET button again to set the hysteresis value. (The hysteresis is the difference required for the thermostat to resume operation after reaching the set temperature and stopping. For example, if we set it to heating mode, heating to 40 degrees, stopping at 35 degrees, and starting again, the hysteresis is 5.)

P2/P3: Limit setting value (non temperature control)

P2 limits the maximum set value (non temperature control), P3 limits the minimum temperature control value (non temperature control). For example, if P2 is set to 50, the maximum stop temperature can only be set to 50

P4: Temperature correction

If there is a deviation between the detected temperature and the actual temperature, this function can be used for calibration. The actual temperature value=the measured value of the temperature controller+the calibration value. For example, if the temperature controller measures 25.6 degrees but the actual temperature is 25.8 degrees, P4 can be set to 0.2, and the final displayed temperature of the temperature controller is 25.8=25.6+0.2

P5: Delay start

This function is generally used for compressor refrigeration. If you purchase this thermostat for use in a refrigerator or freezer, this value must be set. Depending on the back pressure of the compressor, the general setting value is 3-6 minutes. If you are not controlling the compressor or do not need the delay function, simply skip this option

P6: High temperature alarm

Set the high temperature alarm value. When the real-time temperature exceeds this value, the screen displays an alarm prompt. The high temperature alarm value must be greater than the stop temperature value to be effective
