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

 

Long press "SET" switch to P8, press once "SET" Set to ON. According to the "Rst" Restore factory settings.

Can hold on the power-on self-test + - keys and restore factory settings.

 

Instructions for use:

 

Please connect the power supply according to the parameters and the circuit diagram, and connect the cooling or heating equipment to the output terminal.

Enter the internal settings to select heating according to the need P0 Choice H Or refrigeration (entry) P0 Choice C Model)

Set temperature method: press once Set Screen flicker, press up and down to set the required temperature, press Rst Confirm return

Panel OUT Indicator: flashing indicates cooling or heating start delay, often bright display output

Digital tube: display "LLL" Open circuit for the sensor; display "HHH" To force the power off; display "---" High-temperature alarm
