The LightwaveRF Room Thermostat is a user-friendly
device for programming and remotely controlling a
single or several LightwaveRF Radiator Valves. The
Room Thermostat allows you to conveniently set a
weekly heating schedule for individual radiators. This
schedule is then automatically adopted by any Valves
that are linked to the Thermostat. The Room
Thermostat also monitors the room temperature and
provides accurate information on which basis the
LightwaveRF Radiator Valves make their energy
saving temperature adjustments.
