The wall mounted unit is a twin channel RF Programmable room thermostat. The Programmable room thermostat is for central heating and hot water control with modulating/enhanced load compensating boiler regulation.Up to six time and temperature periods can be set to control central heating as well as up to three ON and Off times to control hot water. This enhance load compensating function enables an intelligent conversation with the boiler to achieve the desired room temperature in the most efficient way possible.

To help you save money by burning less fuel, and to minimise room temperature “overshoot” the boiler may stop firing just prior to the desired room temperature being reached. This behaviour including reduced radiator temperature is perfectly normal. You simply set a temperature on the thermostat that you are comfortable with and allow the Comfort II RF Programmer and boiler to do their work.

All programming and adjustment is conveniently done from the Programmable room thermostat making the Greenstar Comfort II RF an excellent solution if your boiler is not easily accessible. The unit has user and installer menus to allow the setting of the temperatures, time programs, monitoring of system information, setting current time/date, daylight savings, maintenance schedules, and pairing the device with the Receiver.

If you are using a Worcester System or Regular boiler, you may require an extra part in order to use the Comfort series of controls. Please contact Worcester for further information. Please note that the Worcester Greenstar Comfort Range will only be compatible with Worcester Greenstar Boilers that feature EMS-BUS capabilities. Please ensure your boiler has this feature by checking your boiler pcb for the connection shown right: worcester comfort compatibility

*Wall mounting is only available when using optional Wall Mounting Accessory kit - Not Included
**5 Year warranty applies when purchased and installed with a brand new Worcester Boiler, otherwise, 1 Year Warranty.
