Long-time press the button of “SET” to enter setting mode:

PO： cooling and heating mode
High temperature starting is cooling mode, please set it to “C”;
Low temperature starting is heating mode, please set it to “H”.

P1: Return Difference setting
In heating mode (H): When the measured value is ≤ Set value – Return Difference, will start output heating until to reach the set value to stop.
In cooling mode mode (C): When the measured value ≥ Set value + Return Difference,will start the output cooling until to reach the set value to stop;

P2: Limit the maximum setting value (It is not temperature- controlling set);

P3: Llimit the minimum setting value (It is not temperature- controlling set);

P4: Temperature correction
When there is a deviation between the measured temperature and the standard temperature, this function can be used for correction. The corrected temperature = the temperature before the correction + the corrected value;

P5 Delayed start-up time (unit: minutes)
When controlling the refrigeration of the compressor equipment, the delay time can be set as needed. When the controller outputs, the equipment will not start immediately, and it needs to start after the set delay time has been run.

P6: High temperature alarm
When the measured value is greater than this value, the temperature value on screen flashes and an alarm is sounded. The output is forcibly disconnected in the heating mode, but the output will not be disconnected in the cooling mode.

P7: Data lock function
Turn on the data lock to keep the current setting unchanged. Under this function, you couldn`t set temperature and all other operations are invalid. If you need to modify it, need to turn off the data lock function.

P8: Restore inital factory settings
Long-time press the button of “SET” to switch to P8, press SET one time to set “on”, then press “ENT” to restore the inital factory settings. You can also press and hold one key to start the machine self-checking and restore inital factory settings.

1),Please connect the power supply according to the circuit diagram, and connect the cooling or heating equipment to the output terminal;

2), Enter the settings to select the heating (enter P0 to select H) or cooling (enter P0 to select C) mode;

3), How to set the temperature: Press SET one time, the screen flashes, press ▲(up) and ▼ (down) to set the required temperature, press ENTER to confirm and return;

4),The OUT indicator light on the panel: flashes to indicate the delay in cooling or heating start-up, and the light is on to indicate the normal output.

5), Digital number zone: Showing “LLL” means the disconnection of sensor; Showing “HHH” means out of the measurement range, when the thermostat will be forced to be power-off; It is in the set state or high temperature alarm state when the temperature number flashes.

1. The input terminal is connected to the power supply. +V is the positive electrode, GND is the negative electrode. Supply power according to the type of power supply, do not exceed the range.;

2. The output type is “relay output”, and the load needs to be connected in series at the output terminal, the maximum capacity is 10A.;

3. After connecting the wire and load, you must first set the cooling or heating. After that, press SET one time when the temperature is displayed normally, the screen flashes, and press ▲(up) and ▼ (down) to set the desired stop temperature;

4. Long-time press the▲(up) and ▼ (down) to restore the factory settings;
