Rf Room Thermostat - Worcester Greenstar Comfort I RF Installation And Operating Instructions Manual

RF Room thermostat

The Room thermostat can only be used in conjunction with the
Programmer/Receiver. The Room thermostat displays the
current room temperature and is also used to set a new
temperature set point. This information is transmitted back to
the Programmer/Receiver to control the boiler output to
maintain the desired room temperature.
Setting a new temperature will not have any effect when the
Programmer/Receiver is in an OFF time period, but will be
stored and take effect during the next ON period.
The display is not backlit, this will reduce the drain on battery
power which will maximise the life of the batteries.
