"This device is used as a differential temperature switch, for example to switch on a circulation pump when a specified temperature difference is reached and to stop the pump when the temperature difference falls by the specified hysteresis.
Example application:Automatic reheating of the hot water storage tankAutomatic activation of the pump in the case of a solar-powered systemTECHNICAL PARAMETERSPower supply: 230 V ACConsumption: up to 0.5 WControl range: +20°C to +80°CHysteresis: +2°C to +35°COutput (potential-free contacts): relay, 5 A/250 V ACProtection class: IP20Temp.
sensor: 2 (included)Operating temperature: 0°C to +50°C"
