Three position switch (Fig. 4)




Constant (Top position): The heating will be on constantlyirrespective of the position of the tappets. The heating will be



controlled by the main thermostat on the appliance and/or anyexternal controls.Timed (Central position): The heating will operate according tothe position of the tappets and be controlled as above.Off (Bottom position): No central heating. Domestic hot water willoperate on demand.

To set the time of day

Turn the timer outer bezel clockwise, to align the pointer with the correct time to the nearest 15 minutes ensuring that A.M./P.M. isconsidered.

Do not at any time attempt to turn the bezel anticlockwise.

To set the timed heating program

The heating will operate when the white tappets are set to the outer edge of the bezel.

To ensure the heating stays OFF set the required tappets inwards towards the centre of the bezel.

Each tappet represents 15 minutes.

For example: If the heating is not required between 10 A.M. and 11 A.M. the four tappets anticlockwise from the 10 A.M. will be setinwards (Fig. 5).
