The operation of the boiler can be automatic if a
programmer is fitted. This may also be used in
conjunction with a room thermostat or other devices to
control temperature.
The boiler thermostat control knob controls the
temperature of the hot water.
The boiler thermostat control knob is situated behind the
control door on the left hand side of the controls facia
panel (See Fig. 2).
Turning the control knob clockwise will increase the
temperature of the boiler which will provide hot water to
the radiators and to the hot water cylinder.
For safety shutdown purposes an overheat thermostat is
included (as shown in Fig. 2).
This will operate only if the water temperature in the
system is in excess of 95°C. This indicates a system fault
and it should be determined by your local service
engineer and rectified before re-lighting the boiler.
