Operating Instructions and Parameter Functions
How to set temperature:
Press the SET key once, and the temperature on the display screen will flash. Use the + △ /- ▽ key to set the required temperature (long press the key to quickly increase or decrease the value). After the setting is completed, press the SET key to confirm and return. At this time, the controller presses Set automatic relay on and off. Generally set around 35°.
Parameter function description:
Press and hold the SET button for 5 seconds to enter the main menu, switch P0-P6 by pressing the button +/-, and press and hold the SET button for 10 seconds, or the controller will automatically confirm and return without any button action.

• P0 cooling/heating mode: long press SET for 5 seconds to display P0, press SET once to set the working mode, and press +- to switch [H is heating
Mode]【C is cooling mode】Press SET once to return, press and hold SET for 10 seconds or if there is no button action, the controller will automatically confirm and complete. The ink inside the ink cartridge needs to be heated, so set the working mode to heating mode H.
Heating mode: When the temperature measurement value ≤ temperature set point, the heating relay is closed, and the heater starts; when the temperature measurement value ≥ temperature set point + hysteresis, the heating relay is disconnected, and the heater is turned off
•P1 hysteresis setting: long press SET for 5 seconds to display P0, press +- to switch to P1, press SET once to set the hysteresis value, and press +- to set
The hysteresis is 0.1-15, press SET once to return after completion, press and hold SET for 10 seconds or if there is no button action for 10 seconds, the controller will automatically confirm the completion. Generally, the hysteresis is set at a value of 1-2.
When the measured temperature value ≤ set value, the relay is closed and the heater starts; when the measured temperature value ≥ set value + hysteresis value, the relay is disconnected and the heater is turned off. For example, the environment is 10°C, the set value is 35°C, and the hysteresis is set to 2°C. After the power is on, the relay closes and the heater starts. When the temperature reaches 37°C, the relay turns off and the heater turns off. When it is turned on, the temperature begins to drop. When it drops to the set value of 35°C, the relay closes and the heater starts again so that the cycle is repeated so that the temperature is not lower than 35°C.
•P2 Maximum temperature setting upper limit: In order to avoid the danger of setting the temperature too high due to misoperation by others, this thermostat has a maximum setting upper limit
Function, which limits the setting range of the maximum temperature set point controlled by the thermostat.
Press and hold SET for 5 seconds to display P0, press + – to switch to P2, press SET once to set the upper limit, press + – to set the highest temperature that can be set, the maximum value is 110, press SET once to return after completion, long press SET or 10 The controller automatically confirms the completion of the second without any button action.
For example: if the temperature is set to 45°C, the set point can only be set up to 45°C. If the temperature set point is higher and the temperature range is to be expanded, it is necessary to adjust the set value of the upper limit first.
• P3 Minimum temperature setting lower limit: In order to avoid ice blockage due to low temperature caused by misuse by others, this thermostat has a minimum setting upper and lower limit function
Can, limit the setting range of the minimum temperature set point controlled by the thermostat.
Press and hold SET for 5 seconds to display P0, press + – to switch to P3, press SET once to set the minimum lower limit, press + – to set the lowest temperature that can be set, the minimum value is -50, press SET once to return after completion, long press SET or 10 seconds without any button action, the controller automatically confirms the completion.
For example: if the temperature set point is set to 20, the minimum temperature set point can only be set to 20°C. If you want to expand the temperature range with a lower temperature set point, you need to adjust the set value of the lower limit first.
•P4 temperature correction: This function can be used when the measured temperature deviates from the standard temperature or due to the special needs of the user’s hardware
Calibration, temperature after correction = temperature before correction + correction value valid range is -7.0~7.0.
Press and hold SET for 5 seconds to display P0, press + – to switch to P4, press SET once to calibrate, press + – to set the correction value, press SET once to return after completion, long press SET or no button action for 10 seconds, the controller will automatically confirm the completion.
For example, the normal display is 35 degrees; when the temperature correction is 0, it will display 35 degrees; when the temperature correction is 1.5, it will display 36.5 degrees; when the temperature correction is -1.5, it will display 33.5. Temperature after = temperature before calibration + calibration value, please ignore if you are not sure.
•P5 Delayed start time: When there is a need to delay the operation of the refrigerator or heater, the delay function can be turned on to protect the life of the equipment. time
The unit is minutes.
Press and hold SET for 5 seconds to display P0, press +- to switch to P5, press SET once to set the delay start time unit is minutes, and press +- to set 0-10
After completion, press SET once to return, long press SET or no button action for 10 seconds, and the controller will automatically confirm the completion.
In heating mode: when the power is turned on for the first time, if the current temperature ≤ the set value, the heater will not start heating immediately, it needs to start after the set delay time, and when the delay start is set to 0, it means that the delay function is turned off.
•P6 alarm temperature setting: when the measured value is greater than this value, the screen will display —— and beep alarm, and at the same time, the output will be forcibly disconnected. for safety reasons,
It is recommended to set the value to≥ 45°C. When it is set to OFF, the high-temperature alarm is invalid; when it is set to ON, the high-temperature alarm is valid, and the default value is 110°. To modify this value, press the SET key again after setting it to ON, and the screen will display the high-temperature value. Adjust the set value by pressing the up and down keys. value, and finally press the ENT key to save.
•P7 data lock function: When the parameter is set to ON, the data function lock will be enabled, which can keep the current set value unchanged.
The set temperature and function are invalid; if modification is required, the data lock function must be turned off, that is, the parameter is set to OFF.
•P8 restore factory settings: Long press SET to switch to P8, press SET once to set it to on, and press Rst to restore factory settings, also can
Press and hold the +/- key for POST and Factory Reset. When the parameter setting is confusing, you can use this parameter to restore the factory value and reset it according to your needs.
How to save settings:
If you want to save the set data, set P7 to ON when the temperature is set and the power is not turned on.
Keep the last setting.
Due to some artificial reasons, the internal settings of the thermostat are confused, and it takes a lot of time to set them one by one. At this time, you can use this function to restore the factory settings.
The specific method is: in the off state, press and hold the + and – buttons at the same time, and then turn on the power, all the above parameters will return to the factory settings.
Indicator light, digital tube status description
•Indicator light: flashing means cooling or heating start delay, always on means the relay is closed
• Nixie tube: display LL means the sensor is open, please check whether the sensor is connected well; display HH means the temperature controller is out of the measuring range Forcibly disconnect the relay; display — is the high-temperature alarm.
