Description

RJ402 serves as a temperature differential switch for switching, for example, a circuit pump when the temperature difference is entered and for the subsequent stop of the pump when the temperature difference is reduced by the specified hysteresis. Example of use፦ Automatic reheating of the DHW cylinder - Automatic connection of the pump to the solar system Parameters፦ Power supply 230 V AC - Consumption do 0.5 W - Control range +20°C to +80°C - Hysteresis +2°C to +35°C - Output (potential-free contacts) relay, 5A/ 250V AC - Temp sensor 2 pcs supplied in the delivery - Operating temperature 0°C to +50°C

Key Features

The differential switch RJ402 is used to switch a circulation pump at a set difference of temperature between CT1 and CT2. The value of the temperature difference for switching is adjustable in the range of 2°C to 50°C.

With the Hys adjustment wheel, the switching time can be changed from 2 °C to 35 °C.

Application: automatic recharging of the hot water tank or automatic switching on of the circulation pump in a solar system
