gramme.

RESET
Should the unit be disconnected from the mains a small
battery symbol will blink on the left hand side of the display.
After the second midnight, i.e. between 24 and 48 hours, the
display will go blank and the will lose its setting. When mains
power is restored it is recommended that the unit be reset by
lowering the front flap and using a small non-metallic object,
e.g. matchstick, press and release the recessed reset button
(marked R/S). This installs the factory pre-set programme and
sets the time to 12.00pm and Monday (MO). The outputs will
be OFF, (see Fig. 1). Note that the colon between the hours
and minutes is blinking. This means the unit is in RUN mode
and will switch the Central Heating and Hot Water on and off
is accordance with the programme. The colon only blinks in
RUN mode.
CHOICE OF 12-HR OR 24-HR CLOCK
At any time during RUN mode the time displayed can be tog-
gled between a 12 hour clock with am/pm indication or a 24
hour clock by pressing and holding both DAY and NEXT ON/
OFF button for 1.5 seconds.
G.M.T./B.S.T.
While in RUN mode the change from Greenwich Mean Time
to British Summer Time and back is achieved by pressing
and holding the + button to add one hour in the Spring or
the – button to put the clock back in the Autumn. After the
first time this change has been made this feature will only
allow the clock to be changed in the correct direction. Take
care when making this change for the first time. If it is made
in the wrong direction the unit will have to be reset and any
user-settings re-entered.

the Central Heating and Hot Water on and off at the times
set. However, useful over-rides are provided which enable the
user to make temporary changes to the ON/OFF times with-
out having to re-programme the unit. The facilities offered by
the over-rides are detailed on the back cover.
REVIEWING PROGRAMMES FROM THE RUN MODE: Press PROG
twice, follow step 2,3,5 & 6 above (Note: step 5 applies only to
FP75 and FP15).
MANUAL OVER-RIDES
While in OFF, AUTO or ALLDAY modes the plus one hour
(+1HR) button can be used to switch from off to on for just
one hour, or to extend and existing on period by one hour.
The extra hour is cancelled by pressing the button again,
pressing the MAN button, or when an on event is reached.
While in AURO of ALLDAY modes pressing the manual (MAN)
button will switch an output which is on to off, and vice
versa. This over-ride will last only until the next programmed
switching event is reached, when the automatic programme
will resume control, or until the button is presses again.
When the above over-ride are selected a bar appears in the
display against the appropriate legend.
ERROR FREE PRORAMMING
ON/OFF times cannot be set out of sequence. The limits of
adjustment are: Setting 1 (first ON) 12.00am to 11.59pm (nor-
mally in the morning).
Settings 2 to 6 (first OFF to last OFF) anywhere between the
previous setting and 23 hours 59, minutes after Setting 1.
The – button stops responding when the pervious Setting is
reached, but the + button continues to its limit, also chang-
ing any later Setting that would have been overlapped.
While becoming familiar with Setting Sequence the ON/OFF
times may become grouped together. If this should happen
use NEXT ON/OFF to select Setting 1, then check/alter each
Setting in turn, using + or – until the desired programme is
entered .
When programming 7 day models, FP75 & CP75, the day be-
ing set appears in the display (see typical displays). With 24
hour models, FP15 & CP15, the day only appears in SET TIME
mode. When models are being programmed in 5 day/2day
mode then the days will show as MOTUWETHFR of SASU.
Should the unit be disconnected from the mains a small bat-
tery symbol will blink on the left hand side of the display.

The following ON/OFF times are programmed at the fac-
tory and are re-instated by pressing the recessed R/S button
