User Instructions - (F24e & F28e ONLY) Optional Programmer
To set the programmer ON and OFF times
Note: The programmer can be set to give a minimum of one and
a maximum of three "ON" and "OFF" times.
Place the slide switch to "SET".
Press the "enter" button. The display will show the first "ON"
time, see diagram 5.
Using the + and - buttons, change the first "ON" time to the time
you require then press the "enter" button twice. This stores the
new time and displays it to confirm it has been stored in the
programmer memory.
Press the "enter" button again. The display will show the first
"OFF" time, see diagram 6.
Using the + and - buttons, change the first "OFF" time to the time
you require. Press the "enter" button twice. The display will
show the first "ON" time.
Press the "enter" button again. The display will now show the
first "OFF" time you have just entered.
Repeat the above for the remaining "ON" and "OFF" times.
When the "ON" and "OFF" times have been set, place the slide
switch to "RUN".
Note: If all three "ON" and "OFF" times are not required, follow
the above instructions but after setting the desired times, set the
other times to show a series of dashes, using the + and -
buttons, see diagram 7. The series of dashes are between
times 23.59 and 0.00.
Helpful Hint If you get confused and wish to start again, press
the "Reset" (res) button and the programmer will revert to the
internal factory set programme. You can now reset the current
time and start again.
To check the programme "ON" and "OFF"
times
The programmed "ON" and "OFF" times can be checked at any
time by moving the slide switch from "RUN" to "SET".
Successive presses of the "enter" button will show the "ON"
and "OFF" times.
Always return the slide switch to "RUN" to return to normal timed
working.
To set the 'Holiday' feature
The programmer has a holiday feature which can be set, if
required, to keep the central heating "OFF" for a period between
one hour and twenty seven days. This can be used, for example,
to keep the central heating "OFF" during a holiday. After the
programmed time has elapsed, the boiler will return to its normal
programmes and switch on the boiler in time for a return from
holiday.
Place the slide switch to " HOL " , the letter "h" will appear on the
display, see diagram 8.
Using the + and - buttons, set the "Holiday" time required.
After the display has shown "twenty three hours", the "h" symbol
on the display will change to a "d". The Holiday time will now be
displayed in days, instead of hours, see diagram 9.
Use the "ON/OFF" button to set the boiler to the required
operation during the "Holiday" period.
Place the slide switch to "RUN".
After the programmed "Holiday" time, the boiler will return to
normal timed operation.
