OPERATION OF

CONTROLS

OPERATING SWITCH

In the position there is no mains electricity to the

appliance.

In the ‘I’ position mains electricity is connected to the

appliance.

CENTRAL HEATING TEMPERATURE CONTROL

The position of this knob will determine the temperature of the water delivered to the radiators between the ‘I’ and ‘MAX’ position. 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 radia- tors.

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 the and the ‘MAX’ position.

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. 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 elec- tronic programmer into the facia of your appliance. Operating instruc- tions 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 red needle has been set to show the sealed system pressure which is required for the appliance to operate effectively. The grey needle will show the actual pressure in the system. This does not apply to any open vent system.
