Third, the parameter function description

Press and hold Set for 5 seconds to enter the internal parameter setting, press up and down to switch P0...P8 and press Rst to confirm the return.

• P0 cooling and heating mode

• High temperature start for cooling mode, please set to C

• Low temperature start for heating mode, please set to H

• P1 hysteresis setting

• In heating mode ( H ): measured value ≤ set value - when the difference is returned, the output is heated to the set value to stop.

• In cooling mode ( C ): When the measured value ≥ set value + hysteresis, start output cooling to set value stop

• P2 maximum setting range: the highest value when setting the temperature does not exceed this value

• P3 minimum setting range: the lowest value when setting the temperature is not lower than this value

• P4 temperature correction

• When the measured temperature deviates from the standard temperature, this function can be used to correct the corrected temperature = temperature before correction + correction value

• P5 delay start time unit: minute

• When controlling the cooling of the compressor equipment, the delay time can be set as needed. When the controller outputs, the equipment will not start immediately. It needs to start after the set delay time.

• P6 high-temperature alarm

• When the measured value is greater than this value, the screen displays --- and the drip sound alarm, while forcibly disconnecting the output.

• P7 data lock function

• Turn on the data lock, you can keep the current settings from being changed. At this time, the setting temperature and function are invalid. If you need to modify, you need to turn off the data lock function.

• P8 factory reset

• Long press SET to switch to P8, press SET once to set to on, press Rst to restore factory settings

• You can also press and hold the +- button to disable the power-on self-test and restore the factory settings.

• Fourth, the instructions for use

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

• Enter the internal settings as needed to select heating (enter P0 to select H ) or cool (enter P0 to select C ) mode

• Set the temperature method: press the Set screen once, press the upper and lower to set the desired temperature, press Rst to confirm the return.

• The OUT indicator of the panel: flashing indicates the cooling or heating start delay, and the steady light indicates the output.

• Digital tube: Display LLL for sensor open circuit; display HHH is out of measurement range, the thermostat will force power off; display --- for high-temperature alarm
