The VRT 350f wireless programmable room thermostat makes installation easy. The easy to wire receiver unit is installed in close proximity to the boiler. The battery operated wireless thermostat unit has flexible siting potential. The VRT 350f has a flexible 7 day or 24 hour time control with independent time control for heating and hot water. When used with ecoTEC combination boilers, the hot water program can be used to provide time control of the 'AquaComfort' system. When used with a system or open vent boiler and additional VR 66 Control centre the VRT 350f hot water channel can be used to time the hot water cylinder charging.
The programmer has 3 independent on/off periods per day, central heating advance function, holiday set-back function, adjustable set-back temperature and 3 room temperature profiles. There is also a calendar function for automatic summer/winter changeover. The thermostat can be set to modulate the boiler maximising fuel savings further.
