USER INSTRUCTIONS
3022 PROGRAMMER OPERATING INSTRUCTIONS
1) Setting the programmer (Example 1)
i) Decide when you want the
'ON' periods. While griping
the Dial Knob slide the dial
tappets rmly as shown. The
tappets may be quite stiff
to move. If you want the
switch 'ON' between 7am
and 10am and between 5pm
(1700 hours) and 11pm (2300
hours), set the tappets as
shown (A to 7, B to 10, C to
17 and D to 23).
Remember:-
Red tappets switch ON
Blue tappets switch OFF
ii) Using the Dial Knob rotate the dial completely at least twice,
clockwise only, to clear the mechanism.
'A' at the rst ON time in the day (7)
'B' at the rst OFF time in the day (10)
'C' at the second ON time in the day (17)
'D' at the second OFF time in the day (23)
2) Setting the Time (Example 2)
Suppose it is 2pm (1400 hours)
when you are making this
adjustment. Using the dial knob
rotate the dial clockwise only
until '14' on the dial is next to
the 'Time' mark, as shown.
Remember that you will have
to reset the time after a power
cut and also when the clocks
change by one hour in spring
and autumn.
Important: Any adjustment to the time setting must be made by
rotating the dial clockwise only.
3) Selecting the Programme Required
The two selector switches operate entirely independently of each other
as follows:
The 3-way selector switch with positions marked TIMED, OFF and ON
is used to operate and override the tappet settings on the clock as
follows:

TIMED (Selector switch in the up position). The clock will switch your
system ON and OFF according to times at which you have set the four
tappet arms. See example 1.
OFF (Selector switch in the middle position). This position will
completely override the tappet setting and the ON-OFF function of
the timeclock enabling you to switch your system o .
ON (Selector switch in the down position). This position operates in
the opposite way to the OFF position. It will completely override the
tappet settings and ON-OFF function of the timeclock enabling you
to switch your system ON (e.g. during the winter when the timeclock
is in an o position).
The 2-way priority switch is set to give the emphasis or priority on
the service which you require. On a cold morning for example you
may want the heating to come on rst. In this case the switch is set to
'HEATING PRIORITY' .
Or you may require two baths in succession, so 'WATER PRIORITY' would
be selected. Whichever priority is chosen, it will remain in that state
until the switch is moved to the other priority position.
To obtain water only, select 'WATER PRIORITY' and turn the room
thermostat down to the lowest setting.
