Product Introduction
This product is a digital temperature control switch with multiple parameter settings and memory. The product is divided into DC12V, DC24V, and AC220V power supplies. The product comes with three buttons (set, add, subtract) to set appropriate parameters and achieve heating or cooling temperature control effects. In terms of display, a 3-digit digital display is used for users to directly read temperature values and view set parameters. At the same time, the product casing comes with double ear fixing holes for easy installation and fixation.

Introduction to Key Settings
1. Set the startup temperature for Po
Press the settings button to enter the internal menu, which defaults to P0. Press the settings button again to set the desired startup temperature using the up and down buttons. Press to change the value, and hold it down continuously to change the value.
2. Set the stop temperature for P1
Press the settings button to enter the internal menu, which defaults to P0. Use the up and down keys to switch to P1, then press the settings button again to set the desired stop temperature
3. P2 sets temperature calibration
Enter the internal menu in the same way, switch to P2 by pressing the up and down buttons, press the settings button again, and set the desired calibration temperature by pressing the up and down buttons. (Note: In the setting, if the detected temperature value is 0.5 ℃ higher than the actual temperature value, the calibration temperature that needs to be set is -0.5 ℃. If the detected value is 1 ℃ lower than the actual temperature, the calibration temperature that needs to be set is 1 ℃. The detected temperature+calibration temperature=actual temperature.)
4. P3 Set Delay Start
Enter the internal menu in the same way, switch to P3 by pressing the up and down buttons, press the settings button again, and set the required delay time in minutes by pressing the up and down buttons. (Note: Delay start is generally used for compressor cooling, and if used for refrigerators and freezers, this value needs to be set. Depending on the compressor back pressure, the general setting value is 3-6 minutes. If you are not using it for control or do not need the delay function, skip it directly.)

设置方式: 按设置键进入内部菜单,通过 P0 值设置启动温度,通过 P1 值设置停止温度。 Setting method: Press the settings button to enter the internal menu, set the start temperature through P0 value, and set the stop temperature through P1 value. | 设置方式: 按设置键进入内部菜单,通过 P0 值设置启动温度,通过 P1 值设置停止温度。 Setting method: Press the settings button to enter the internal menu, set the start temperature through P0 value, and set the stop temperature through P1 value. | |
使用案例: 控制热水器,加热到 50℃停止,温度回到40℃再次加热,如何设置? 1、确定工作模式为加热模式,启动温度<停止温度。 2、按设置键进入内部菜单,选择 P0启动温度,设置 P0 值为 40℃。 3、按设置键进入内部菜单,选择 P1停止温度,设置 P1 值为 50℃。 Use case: How to set the water heater to stop heating when it reaches 50 ℃ and then reheat when the temperature returns to 40 ℃? 1. Set the working mode to heating mode, with the starting temperature being lower than the stopping temperature. 2. Press the settings button to enter the internal menu, select P0 startup temperature, and set the P0 value to 40 ℃. 3. Press the settings button to enter the internal menu, select P1 to stop temperature, and set the P1 value to 50 ℃. | 使用案例: 控制机柜散热器,加热到26℃停止,温度回到 30℃再次启动散热器,如何设置? 1、确定工作模式为制冷模式,启动温度>停止温度。 2、按设置键进入内部菜单,选择 P0启动温度,设置 P0 值为 30℃。 3、按设置键进入内部菜单,选择 P1停止温度,设置 P1 值为 26℃。 Use case: How to set the control cabinet radiator to stop heating up to 26 ℃ and restart when the temperature returns to 30 ℃? 1. Set the working mode to cooling mode, with the starting temperature greater than the stopping temperature. 2. Press the settings button to enter the internal menu, select P0 startup temperature, and set the P0 value to 30 ℃. 3. Press the settings button to enter the internal menu, select P1 to stop temperature, and set the P1 value to 26 ℃. |
Using examples
How do I set the temperature for hatching chicks to 37.5 ℃~38 ℃?
1. Short press the settings button to display P0 on the screen, then short press the settings button to display the current startup temperature. Press the up/down button to adjust the startup temperature to 37.5 ℃ (automatically exits and saves after 5 seconds of inactivity).
2. Short press the settings button to display P0 on the screen, press the up button to switch to P1, then short press the settings button to display the current stop temperature, and press the up/down button to adjust the stop temperature to 38C
3. After the setting is completed, the thermostat will control the heating equipment to heat at 37.5 ℃. When the temperature rises to 38 ℃, the temperature will stop and drop to 37.5 ℃ to start heating again and continue the cycle.
I actually measured a temperature of 35 ℃, but the thermostat shows 35.6 ℃. How can I calibrate it?
1. Short press the settings button to display P0 on the screen, press the up button to switch to P2, and then press the settings button to display the current temperature calibration value. Press the up/down button to adjust the calibration to -0.6 ℃ (the temperature displayed on the thermostat is 0.6 ℃ higher than the actual measured temperature)
