SETTING THE CLOCK
Press PROG to display the time of day (the display blinks). Press DAY
(the display stops blinking) to select today (1 = Monday, 6 = Saturday
etc.). Press and hold down the + or - button to change the time quickly
in ten minute steps, or press and release to change the time by one
minute.
When the day and time are correct, press and release PROG once to
start the clock and further press and release as necessary until the
colon starts blinking, (RUN mode.) The intermediate stages are
explained in the Setting Instructions.

WINTER TIME / SUMMER TIME CLOCK
When the clocks are changed from Summer Time to Winter Time (or
vice versa) there is no need to alter the clock by entering programming
mode (i.e. pressing the PROG button). Instead just press and hold
down the - button to change from Summer Time to Winter Time or the
+ button to change from Winter Time to Summer Time. The first time
this is done (after a RESET) the clock is set and can only be changed
by one hour as appropriate.
If a mistake is made, e.g. pressing the + button in the autumn when the
- button should have been pressed, rectify the problem by pressing the
correct button and then re-setting the clock by one hour as appropriate.
(Refer to SETTING THE CLOCK above).
TIME OR TEMPERATURE DISPLAY
The default display in RUN mode shows the time of day. This may be
changed to display the actual temperature being sensed by pressing
both COPY and NEXT buttons together. Return to time display by
pressing them together again.

HOLIDAY MODE
Whilst in thermostat mode pressing the DAY button will activate the
holiday mode. The display will change to that shown in Fig. 7 with a
number indicating the default holiday period of 00 days. Use the
buttons to adjust the control temperature as required, and use the
+ or - buttons to set the number of days required, in the range 1-99
days. If the number of days is left at 00 then the unit will return to normal
at event 1 the following day. When the selected number of days have
elapsed the unit will automatically return to normal, controlling
temperatures to the set programme.
Control may also be restored to normal by pressing the
together.
USER OVERRIDES
Whilst the unit is operating normally in RUN mode the following
overrides are available:

Pressing this button once causes the current control temperature to
last for an extra hour. Press it twice for an extra 2 hours, and three times
for 3 hours. Pressing a fourth time will remove the override.
For example, a comfort temperature of 21°C programmed to end at
22:30 could be extended passed midnight. Alternatively, a morning
set-back temperature of 15°C could be extended to effectively cancel
a midday comfort setting.
