Instructions for use:

Indicator light and digital tube status indication

1. Indicator light: If the relay is disconnected, the indicator light goes out. If the relay is on, the indicator light will be on.

2. Digital tube: If the digital tube displays "- - -", please check as follows: 1. Whether the temperature sensor is lost or damaged. 2. Whether to enable high temperature protection in heating mode 3. Whether to enable low temperature protection in cooling mode. If it is in both protection modes, the relay will open

 

Buttons: There are three buttons on the thermostat: button +, button -, and SET button.

1. Button+: used for rapid accumulation of numbers.

2. Button-: Used for rapid decrement of numbers.

3. SET key: The SET key has three functions: 1. Setting the temperature 2. Viewing the temperature and working mode 3. Setting the parameters.

4. SET (short press): The digital tube will flash according to the number of short presses, and the temperature can be set when flashing. Once done, the temperature will be automatically saved within 5 seconds. You can also triple-tap to save.

5. Setting (long press): You can enter the actual temperature and working mode interface, the digital tube (upper) is the actual temperature, and the digital tube (lower) is the working mode. C means cooling, H means heating mode, OFF means stop.

Mode settings:

1. High temperature start refrigeration mode: set start temperature > stop temperature.

If the detected temperature ≥ start temperature, the relay will turn on and start cooling mode; if detected temperature ≤ stop temperature, the relay will turn off and stop cooling mode. For example: we set the starting temperature to be 30°C and the end temperature to be 25°C. When the detection temperature is ≥30°C, the relay is turned on and the indicator light (red) is on; when the detection temperature is ≤25°C, the relay is turned off and the indication is The light goes out.

2. Low temperature start heating mode: set start temperature < stop temperature.

If the detected temperature is less than or equal to the start temperature, the relay will be turned on and the heating mode will be started; if the detected temperature is greater than or equal to the stop temperature, the relay will be turned off and the heating mode will be stopped. For example: we set the starting temperature to be 25°C and the end temperature to be 30°C. When the detection temperature is ≤25°C, the relay is turned on and the indicator light (red) is on; when the detection temperature is ≥30°C, the relay is turned off and the indication is The light goes out.

3. Start temperature = stop temperature The temperature control will be turned off and the relay will be disconnected.
