Product Features

Instructions

1. Connect the power supply and load according to the wiring method shown in the diagram, connect them correctly, and the display screen will light up;

2. Press either the "+" or "-" buttons on the left to start the temperature display. The starting temperature on the screen will start flashing. At this time, you can adjust the starting temperature by pressing the "+" or "-" buttons. After setting it, wait for 5 seconds, and the system will automatically save the data;

3. Press either the "+" or "-" buttons on the right to stop the temperature. The stop temperature on the display screen will start flashing. At this time, you can adjust the stop temperature by pressing the "+" or "-" buttons. After setting it, wait for 5 seconds, and the system will automatically save the data;

4. After the setting is completed, the system will automatically determine whether it is heating mode or cooling mode:

Heating mode: Start temperature<Stop temperature

Cooling mode: Start temperature>Stop temperature

Give examples to illustrate

1. High temperature start-up - cooling mode

When the set starting temperature value is greater than the stopping temperature value; When the detected temperature is ≥ the starting temperature, the relay closes and the refrigeration equipment works; When the detected temperature is ≤ the stop temperature, the relay will disconnect and the refrigeration equipment will stop working. Example: Set the start temperature to 30 ℃ and the stop temperature to 25 ℃. When the detected temperature value is ≥ 30 ℃, the relay will close and the start indicator light (red) will light up; When the detected temperature value is less than 25 ℃, the relay will disconnect and the stop temperature light (green) will turn on.

2. Low temperature start heating mode

When the set starting temperature value is less than the stopping temperature value; When the detected temperature is ≤ the stop temperature, the relay closes and the heating equipment works; When the detected temperature is ≥ the stop temperature, the relay will disconnect and the refrigeration equipment will stop working. Example: Set the start temperature to 25 ℃ and the stop temperature to 30 ℃. When the detected temperature value is ≤ 25 ℃, the relay will close and the start indicator light (red) will light up; When the detected temperature value is ≥ 30 ℃, the relay will disconnect and the stop temperature light (green) will turn on.
