As a wireless room thermostat, the radio receiver works together with the VTX-SP remote control unit. The room thermostat consists of a remote control unit that serves as a radio room temperature sensor for measuring the temperature in the room and as a transmitter, and at least one radio receiver as a controller that is directly wired to a heating element. One or more radio receivers from the VTX series can be assigned to the remote control unit. If the installed power exceeds the specified switching capacity of the respective radio receiver, the heating elements must be switched via additional load relays type LS-E or radio receivers. The installation takes place on the wall near the heating element or in the sub-distribution board. Display: status LED. Protection class II. Protection type: IP44. Operating temperature: 0-40°C.
