Description

The electronic relay is used to control electrothermal valve drives. It is possible to implement individual room control in connection with the 4-fold
universal interface. The device is intended for insertion in a 60 mm, flush-mounted, combined wall and joint box.

The control of the electronic relay is carried out by an output of the universal interface and is dependent on the telegrams of a room temperature controller.

The thermal valve drive of the heating valve is switched by the semi-conductor output both noise-free and with a low rate of wear.

The connection with the universal interface is carried out via a twin-core cable and a connecting terminal (white/yellow). The maximum cable length is 10 m. The operating voltage for the thermal valve drive of the heating valve is carried out via the device as two-pole with a plug-in, screw terminal.
