VEMER - VE481800 - Thalos RF Nero wall-mounted RF thermostat with touch screen
The VEMER Thalos RF Nero (VE481800) is a wall-mounted radio frequency thermostat with a touch-screen keypad, designed for wireless control of heating and cooling systems through Vemer RF remote actuators. The black finish and large blue backlit LCD give the device an elegant, modern appearance suitable for any room.
Wireless RF control
Operating at 433.92 MHz, the Thalos RF Nero sends radio frequency signals to remote actuators (RX.16A, RX1-8A, RX4-8A, RX7-5A, RX1-8A P), eliminating the need for wiring between the thermostat and the load. This makes it ideal for retrofitting existing installations.
Touch-screen interface and keypad lock
The capacitive touch keypad with two icons provides intuitive operation. A password-protected keypad lock prevents unauthorised changes, useful in public or shared environments.
