7 day or 24 hour plug-in digital programmer for ecoTEC boilers. The programmer has 3 independent on/off periods per day, central heating, advance and holiday set-back. Central heating and hot water can be programmed independently.
When used with ecoTEC combination boilers, the hot water program can be used to provide time control of the Aqua Comfort system.
When used with a system or open vent boiler an additional VR 65 Control Centre is required. The hot water channel can then be used to time the hot water cylinder charging. An additional room thermostat (e.g. VRT 30) should be used for central heating temperature control.
The VRT 50 room thermostat cannot be used with this programmer.
