ADVANCE CONTROL
The advance control allows you to start an ON or OFF period early without altering the tappet, time
or programme selection settings. Moving the advance control to the extreme right brings forward
the operation of the next tappet. The switch state indicator then changes to the appropriate number.
When the next tappet passes the time line, normal operation returns.
When the programme selector is in the All Day position, tappets 2 and 3 do not operate. If you
require switching the system OFF for the day, after the morning switch ON, you will need to step
forward with the advance switch until the number 4 is shown in the switch state indicator.
If you wish to switch ON and OFF by hand or vice versa, before the next automatic switching
operation, the advance control must be operated until the switch state indicator is returned to the
correct automatic sequence.
EXAMPLE: If you turn the system ON
again after the preset night shut down
time, when you turn it OFF before retiring
make sure to operate the advance switch
again until the number 4 is displayed in
the switch state indicator so that the red
tappet number 1 will switch the system
ON in the morning.
DO NOT OPERATE THE ADVANCE
SWITCH WHEN A TAPPET IS AGAINST
THE TIME LINE.
SWITCH STATE INDICATOR
Located above the ADVANCE switch, the switch state indicator shows you the number of the tappet
which operated last.
Eg. If the system was switched ON by tappet 1 at 7:00am and it is now 9:00am, providing that no
further tappets operations have past, a number 1 should show in the aperture.
If the switch state indicator does not agree with the programme set on the dial, rotate the dial one
whole turn and reset to the correct time of day. This will ensure that the switch state corresponds to
the last tappet operation.
