Programmer/Receiver

The boiler fascia mounted unit is a twin channel Programmer/Receiver and is connected to an RF Room thermostat transmitter.
The Programmer/Receiver is for central heating and hot water control with modulating/enhanced load compensating boiler
regulation. 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 save the customer money by burning less fuel, and to minimise room
temperature "overshoot" the boilers burner may stop firing just prior to the desired room temperature being reached. This
behaviour including reduced radiator temperature is perfectly normal. The customer should simply set a temperature on the
thermostat that they are comfortable with and allow the room thermostat and boiler to do their work.
The Programmer/receiver has up to three sets of ON and OFF times that can be set to control central heating and hot water.
The unit has user and installer menus to allow the setting of the time programs, monitoring of system information, setting current
time/date, daylight savings, and pairing the device with the Room thermostat.
