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
vica 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.

The TP75H may be converted to control at a constant, user selected,
temperature by pressing and holding down the

of 8°C (or 46°F), which may be changed as required using the
button. The unit will stay in thermostat mode until the

FROST THERMOSTAT MODE
Whilst in thermostat mode the TP75H may be set to guard against
possible frost damage in areas where the unit (or its remote sensor) is
fitted. The control temperature may be set to a suitable level using the
or
buttons. The unit will stay in frost thermostat mode until the
and
are pressed 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.

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.

BATTERY MAINTENANCE
New batteries will provide the power for switching the outputs on and
off for approximately 2 years. When the batteries volts fall to the
minimum level needed to maintain operation a battery symbol will blink
in the display. When this symbol appears both batteries should be
replaced with high quality alkaline cells. Operation will continue
normally until the 15th midnight after the symbol started blinking and
then the unit will switch off all outputs, and shut down with just the time
and the blinking battery displayed. Whilst the battery symbol is still
blinking, the old batteries may be removed and new batteries placed
in the sleeve provided and inserted within one minute. Internal
circuitry will maintain the user set programme memory during this
period.
