Product description
Differential temperature switch RJ402
It serves as a differential temperature switch (e.g. to switch on the circulation pump at the specified
of the temperature difference and the subsequent switch-off of the pump when the temperature difference drops by the specified amount
hysteresis)
The regulator can be used for:
- automatic charging of the DHW tank
- automatic control of the circulation pump in the solar system
- Power supply: 230 V AC
- Consumption: up to 0.5 W
- Range set. temperature: +20°C to +80°C
- Set hysteresis: +2°C to +35°C
- Outputs (potential-free contacts): relay, 5A/ 250V AC
- Degree of protection: IP20
- Max. number of temperature sensors: 2
- Working temperature: 0°C to +50°C
