Description
The RJ401 is used to switch on a circulation pump when a specified temperature is reached and to stop the pump when the temperature falls by the specified hysteresis.
Example application:
- Automatic activation of the pump when the set temperature is reached
- Automatic switching on of the boiler when the temperature of the water in the hot water storage tank falls
