P0Refrigeration and heating mode

High temperature start for refrigeration mode, please set asC

Low temperature start is heating mode, please set asH

P1Backlash setting

Heating modeH): measured value is less than or equal to the set value of hysteresis when heated to the preset value stop start output

Refrigeration modeC): measured value is more than the set value and start output to the set value of refrigeration stop back difference

P2Maximum setting range: the maximum value does not exceed this value when setting temperature

P3Minimum setting range: when setting temperature, the minimum value is not less than this value

P4Temperature correction

This function can be used to correct the corrected temperature when there is a deviation between the measured temperature and the standard temperature=Temperature before correction+Correction value

P5Delay start timeUnit: min.

When controlling the refrigeration of compressor equipment, the delay time can be set according to the requirement. When the controller outputs, the device will not start immediately and start after the set delay time is set

P6High temperature alarm

When the measurement value is greater than this value, the screen displays---The alarm is broken and the output is forced to disconnect

P7Data lock function

Open the data lock, you can keep the current settings are not changed, the setting temperature and function are invalid, if you need to modify, you need to close the data lock function
