Press and hold SET for 5 seconds to enter the main menu settings, press +- to switch P0...P8 long press SET or 10 seconds without button action controller automatically confirm return

P0: cooling and heating mode

Press and hold SET for 5 seconds to display P0, press SET once to set the working mode, press +- to switch [H is heating mode] [C is cooling mode] Press SET once to return, long press SET or 10 seconds without button action controller automatically confirm carry out

In the cooling mode: when the temperature measurement value ≥ temperature set point, the refrigeration relay is closed, the refrigerator starts; when the temperature measurement value ≤ temperature set point - the return difference, the refrigeration relay is disconnected, the refrigerator is closed

In the heating mode: when the temperature measurement value ≤ temperature set point, the heating relay pulls in and the heater starts; when the temperature measurement value ≥ temperature set point + hysteresis, the heating relay is turned off and the heater is turned off.

P1: Difference setting

Press and hold SET for 5 seconds to display P0, press +- to switch to P1, press SET once to return the difference, press +- to set the difference to 0.5-15, press SET once when finished, long press SET or 10 seconds without button Motion controller automatically confirms completion

In the cooling mode: when the temperature measurement value ≥ the set value, the relay is closed, the refrigerator starts; when the temperature measurement value ≤ the set value - the difference value, the relay is turned off and the refrigerator is turned off.

For example, the environment is 30 °C, the set value is 25 °C, and the hysteresis is set to 2 °C. After the power is turned on, the relay closes the refrigerator to start. When the cooling reaches 23 °C, the relay turns off the refrigerator and the refrigerator is turned off. The opening temperature starts to rise. When it rises to the set value of 25 °C, the relay closes the refrigerator to start again, so the repeated cycle control temperature is not higher than 25 °C.

In the heating mode: when the temperature measurement value ≤ the set value, the relay is closed, the heater is started; when the temperature measurement value ≥ the set value + the return value, the relay is turned off and the heater is turned off.

For example, if the environment is 10 °C, the set value is 25 °C, and the hysteresis is set to 2 °C. After the power is turned on, the relay closes the heater to start. When it is heated to 27 °C, the relay turns off the heater, and the heater is turned off. The opening temperature begins to decrease. When it drops to the set value of 25 °C, the relay closes the heater again, so the repeated cycle control temperature is not lower than 25 °C.

P2 maximum temperature setting upper limit:

In order to avoid the danger of setting the temperature too high due to the misoperation of others, the temperature controller has the highest setting upper limit function, which limits the setting range of the highest temperature setting 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 settable temperature, the maximum value is 110, press SET once after completion, press SET or 10 Second no button action controller automatically confirms completion

For example: set to 60 temperature set point can only be set to 60 ° C. If the temperature set point is to be expanded, the upper limit set value needs to be adjusted first.

P3 lowest temperature setting lower limit:

In order to avoid the ice blockage caused by the misoperation of others, the temperature controller has the lowest setting upper and lower limit functions, which limits the setting range of the lowest 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 settable temperature, the lowest value is -50, press SET once after completion, press SET or 10 seconds without button action controller automatically confirms completion

For example: set to 2 temperature set point can only be set to 2 °C minimum. If the temperature set point is to be expanded at a lower temperature range, you need to adjust the lower limit set value first.

P4 temperature correction

When the measured temperature is deviated from the standard temperature or due to special needs of the user's hardware, this function can be used for correction. The corrected temperature = temperature before correction + correction value The 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 correct, press +- to set the correction value, press SET once after completion, long press SET or 10 seconds without button action controller automatically confirms completion

For example, the normal display is 25 degrees; when the temperature is corrected to 0, it displays 25 degrees; when the temperature is corrected to 1.5, it shows 26.5 degrees; when the temperature is corrected to -1.5, it shows 23.5;

P5 Delay start time Unit: minute

When the refrigerator or heater is working with a delay, the delay function can be turned on to protect the life of the device.

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 minute, press +- to set 0-10 minutes, press SET once after completion, press SET for 10 seconds No button action controller automatically confirms completion

In the cooling mode: the first time the power is turned on, if the current temperature ≥ the set value, the refrigerator will not start the cooling immediately, and it needs to run after the set delay time.

In the heating mode: the first time the power is turned on, if the current temperature ≤ the set value, the heater will not start the heating immediately, and it needs to run after the set delay time.

The chiller starts immediately when the downtime between the two starts of the chiller or heater is greater than the set value of the delay start time;

When the stop interval between the two starts of the refrigerator or heater is less than the set value of the delay start time, the device can start after restarting the set delay time of the set after the run. The delay time is calculated from the moment of shutdown.

For example, the setting delay is 5 minutes in the cooling state, the cooling device starts to delay after the power is turned on, and the refrigerator is turned on after 5 minutes. When the required temperature is reached, the refrigerator stops, and the timing starts, when the next cooling start timing is completed. Work, unfinished time to wait for the end of the time to work, the LED indicator flashes during the delay

When the delay start is set to 0, it is equal to the off delay function.

P6 button tone switch

Press and hold SET for 5 seconds to display P0, press +- to switch to P6, press SET once to set whether to enable button sound, press +- to set on/off, press SET once after completion, long press SET or 10 seconds without button action control Automatic confirmation is completed

When the buzzer switch is set to on/off, the button will sound when the button is activated, and the buzzer will be turned off when the button is set to off.

P7 high temperature alarm

Press and hold SET for 5 seconds to display P0, press +- to switch to P7, press SET once to display on/off (set to off to turn off secondary function). Set to on and press SET once to set high temperature alarm temperature point, press +- to set 0 ~110, press SET once after completion, long press SET or 10 seconds without button action controller automatically confirms completion

The high temperature alarm setting range is 0-110 or off for the secondary function. After reaching the high temperature alarm, the buzzer will make a rapid drip sound and force the relay to be disconnected.

For example, we need to warm a liquid or space to 40 degrees, set 80 degrees as a dangerous temperature, and start the high temperature alarm relay to disconnect the buzzer when the temperature is higher than 80 degrees due to external irresistible factors. Alarm, promptly remind the staff to take corresponding measures to recover the loss! The alarm temperature can be set according to actual needs. If you do not want this function, you can set the temperature to off. Note that when the normal temperature is restored, the high temperature alarm thermostat is automatically released.

P8 Factory reset

Due to some human reasons, the internal setting of the thermostat is confusing. It takes a lot of time to set the item. In this case, you can use this function to restore the factory settings. The specific method is

Press and hold SET for 5 seconds to display P0, press +- to switch to P8, press SET once to set to on or off, on to restore factory settings, off to not perform any action, press SET to return after completion, long press SET or 10 seconds The clock no button action controller automatically restores the factory settings parameters as shown in the table below.
