XK-W3012 Electronic Thermostat Digital Display Temperature Control Switch Wide Temperature -30~300 Degrees

1. How to set the temperature?

The real-time temperature is displayed when the thermostat is powered on. Press the SET button once and the screen flashes. Press the up and down buttons to set the temperature

2. How to enter the internal settings?

Press and hold SET for about 5 seconds to enter the internal setting. Press ENT during the setting process to confirm the return.

In normal operation, long press ENT to switch on and off.

3. P0: working mode

This setting is the main one. This value should be set when the thermostat is used for the first time. If it is used for heating and heating, it should be set to H. If it is used for cooling and cooling, it should be set to C.

4. P1: Hysteresis setting

The return difference is the difference required when the thermostat reaches the set temperature and stops working again. For example, if we set the heating mode and the temperature is 37-40 degrees, then the return difference is 3

5. P2-P3: Set the limit level

This function is to set the temperature limit range, not to participate in the actual set temperature. We know that the setting range of the thermostat under normal conditions is -5 ~ 120. If you do n?™t want such a large range, you can use this function to shorten the setting range. If P2 is set to 50 and P3 is set to 20, then the temperature The setting range of the controller can only be set between 20-50, do n?™t set it if you do n?™t understand it or do n?™t need to limit it.

6. P4: Temperature correction

This function is used for temperature calibration. If there is a deviation between the measured temperature and the actual temperature, this function can be used to calibrate. The corrected value = measured value + corrected value. For example, if the measured temperature is 25.6 degrees and the actual is 25.8 degrees, P4 can be set Is 0.2, then the final temperature is 25.6 + 0.2 = 25.8

7. P5: Delay start

This function is generally used for compressor refrigeration. If you purchase this thermostat for refrigerator freezer, this value must be set. The general setting value is 3-6 minutes according to the back pressure of the compressor. If you are not controlling the compressor Or do not need the delay function, please do not set

8. High temperature alarm

Set a heat preservation alarm value, when the real-time temperature exceeds this value, the screen and the buzzer will simultaneously prompt the alarm, and also cut off the output, to protect the safety of the circuit, the screen HHH prompts when the alarm occurs, the buzzer beep beep-

9. Data lock

If your setting value needs to be protected to prevent others from modifying it arbitrarily, you can enter P7 after setting your parameters and set it to 0N. After setting, the temperature and internal parameters will not be modified unless P7 is set to Off

10. P8: Restore factory settings

When the setting value is confusing or there is a fault, you can enter P8 and set it to 0N to restore the factory settings, or you can hold down the up and down keys to restore the factory settings
