The timeSWITCH 140 has independent time control for central 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 65 Control Centre the timeSWITCH 140 hot water channel can be used to time the hot water cylinder charging. An additional room thermostat (eg VRT 30) should be for central heating temperature control.
The programmer has 3 independent on/off periods per day, central heating advance function and holiday set-back function. Calendar function for automatic summer/winter changeover.
The timeSWITCH 140 cannot be used with the VRT 50 room thermostat.
