7.1 Setting the Timer
The Electro-Mechanical Timer allows the central heating
system to be set every 15 minutes.
Using the three position switch the timer will allow either
constant operation, timed operation or central heating off.
Move the switch button by sliding to the desired position.
Three position switch (Fig. 7)
Constant (Top position): The heating will
be on constantly irrespective of the position
of the tappets.The heating will be controlled
by the main thermostat on the appliance
and/or any external controls.
Timed (Central position): The heating will
operate according to the position of the
tappets and be controlled as above.
0 Off (Bottom position): No central heating.
Domestic hot water will operate 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. is considered. Do not at any time attempt to
turn the bezel anti-clockwise.
To set the timed heating program
Decide which times of the day the central heating is
required.
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 set inwards (Fig. 8).
