PROGRAMMER TIMER
The programmer has 3 time zones per day for each day of the
week. Each day can be programmed for the requirements of
that day, giving 7 programmed days or, using the copy facility,
any number of days can be the same. If a particular time zone
is not required then the ON and OFF periods should be
programmed for the same time.
Each button has an auto repeat function.

STATUS
Enables the selection of programme hours, all day usage or 24
hour.
If the "Programme Hours" option is selected the boiler will go
on and off, subject to the times programmed.
If ALL DAY usage is selected the boiler will come on at the first
"ON" period selected and off on the last "OFF" period selected,
ignoring all other time settings. Based on the above backup
programme this means the boiler would run, subject to any
other external controls, from 07:30 to 22:00 hours.
If 24 HOUR is selected the programme times will be ignored
and the boiler will run subject to the external controls until one
of the other options is again selected.

The correct day can be selected by use of the [UP] or [Down]
button and, when correct, the [ENTER] button should be
pressed. The time and date will now be displayed as follows:-
with first two digits, the hours, flashing.
By use of the [UP] or [DOWN] button the correct hour is
selected and the [ENTER] button pressed. The minutes will
now be flashing and, by use of the [UP] or [DOWN] button, the
correct minutes selected and the [ENTER] button pressed.
This method is repeated until the correct day, month and year
are selected. On selecting the correct year and pressing
[ENTER] the hours will flash. Then, if all the data is correct, the
[EXIT] button should be pressed for the control to accept this
information.
ADVANCE
Enables the programme to be advanced by one hour.
The following display will be available:-
If the [YES] button is pressed and the programmer is in an
OFF period the boiler will be brought on for one hour, subject
to external controls. If the boiler is on with less than one hour
to a programmed off period then the difference between this
time and one hour is the time of the extended on period. If the
boiler is in the 24 hour mode then this option will have no
effect.
