P0: Refrigeration and heating mode
High temperature start for the cooling mode, please set to C
Low temperature starting for the heating mode, please set toH
P1: Return difference setting
Heating mode H): measured value is less than or equal to the set value of hysteresis when heated to the preset value stop-start output
Refrigeration mode C): measured value is more than the set value and starts output to the set value of refrigeration stop back difference
P2: Maximum setting range
The maximum value does not exceed this value when setting the temperature
P3: Minimum set range
The minimum value is not lower than the value of the set temperature
P4: Temperature correction
This function can be used to correct the temperature and the standard deviation of the standard temperature=Temperature before correction+Correction value
P5: Delay start time (Unit: Min)
When the refrigeration of the compressor equipment is controlled, the delay time can be set according to the need, and the device can not be started immediately when the controller output is output.
P6: High temperature alarm
When the measured value is greater than the value of the screen display-And sound alarm, at the same time forced to disconnect the output
P7: Data lock function
Open data lock, you can maintain the current settings are not changed, the temperature and function are not set at this time, such as the need to modify, you need to close the data lock function
P8: Restore factory settings
