Differential temperature switch RJ402 ELEKTROBOCK

Product detailed description

RJ402 differential temperature switch

It serves as a differential temperature switch (e.g. for switching on the circulation pump at a set
the temperature difference and then switching off the pump when the temperature difference drops by the specified
hysteresis)
The controller can be used for:
- automatic recharging of DHW tank
- automatic control of the circulation pump in a solar system
- Power supply: 230 V AC
- Power consumption: up to 0.5 W
- Range set. temperature range: +20 °C to +80 °C
- Hysteresis setting: +2°C to +35°C
- Outputs (potential-free contacts): relay, 5A/250V AC
- Degree of protection: IP20
- Max. number of temperature sensors: 2
- Operating temperature: 0 °C to +50 °C
