OPERATION OF
CONTROLS
The appliance is fitted with the following controls:
OPERATING SWITCH
In the ‘0’position there is no mains electricity to the control
board. In the ‘I’ position mains electricity is connected to the control
board.
CENTRAL HEATING TEMPERATURE
CONTROL
The position of this knob will determine the temperature of the
water delivered to the radiators between fully clockwise and anti-
clockwise to the mark. When the knob is turned anti-clockwise
past the ‘I’ position towards the ‘’(Summer Position), then the
appliance will operate in the HOT WATER mode only and no heat will
be delivered to the radiators.
DOMESTIC HOT WATER TEMPERATURE
CONTROL
The position of this knob will determine the temperature of the
water delivered at the domestic hot water taps between fully
clockwise and anti- clockwise positions.
By slightly reducing the flow of domestic water from the tap, the
delivery temperature of the water will be further increased. This is of
particular advantage in the winter, for example to increase bath water
temperature and to remove heavy grease deposits on plates, etc. Also
this will provide an added advantage of reducing the delay before hot
water is obtained.
FACIA MOUNTED PROGRAMMER (if fitted)
Your installer may have mounted either a mechanical or an
electronic programmer into the facia of your appliance. Operating
instructions are supplied with the programmer.
RESET BUTTON
Press this button in for five seconds if any of the indicator lights
are flashing slowly.
SYSTEM PRESSURE GAUGE
The grey needle will show the actual pressure in the system.
When operating the pressure indicated must not be greater than
2.5bar. If it is then contact your installer.
