FITTING AND USER’S OPERATING
INSTRUCTIONS
Integral 24 Hour Electro-Mechanical &
7 Day Electronic Timer Kits
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. 3)
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. 4).
