Room temperature controller with changeover contact R.1/R.3 black, glossy 20262045

Intelligent thermal comfort control

This room temperature controller is a discreet yet functional element of the climate management system in any home or office. The device is designed to control electric heating, ensuring optimal temperature and user comfort. Its elegant, black, glossy design makes it blend perfectly into modern interiors. Flush-mounted installation provides an aesthetic appearance and minimizes cable visibility.

Precision and reliability in operation

The controller uses a bimetallic temperature sensor, which guarantees precise measurements in the range of 5 to 30°C. The characteristics of the switching contacts (NO/NC) provide a delayed reaction to short-term voltage surges, which is particularly important when connecting devices with motors or other loads with high inrush current. A hysteresis of 0.5 K allows maintaining a stable temperature without unnecessary fluctuations. Thanks to this, the device will not turn the heating on and off too often, which translates into energy savings and extends the life of connected devices.

Installation and compatibility

The controller is designed for flush-mounted installation and has a two-wire connection, which simplifies its installation even in existing electrical installations. It meets the requirements of protection class I and has a protection degree of IP20, which means it is protected against touching with fingers and against the ingress of solid objects larger than 12.5 mm. The maximum voltage on the contacts is 400V, which ensures compatibility with most standard electrical installations. The housing color (RAL 9005) is classic black, which fits many interior designs.
