Wireless single-channel switch as part of the EasyLink 868 system. Communication between the room controller and the actuator takes place wirelessly at a carrier frequency of 868 MHz – a tried-and-tested standard in the market and reliable for applications in both domestic and industrial environments. No chiselling of walls is required for installation, making the EasyLink 868 system ideal for renovation, refurbishment or retrofitting. The EV 1K-EasyLink surface-mounted wireless relay enables the control of electric heating systems (16 A switching current). Floor temperature limit can be set via a remote sensor – ideal for electric underfloor heating. Up to eight single-channel switches can be connected to a single thermostat and combined to form one room. Complies with the EU Ecodesign Regulation.
