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.

THERMOSTAT MODE

The TP75M may be converted to control at a constant, user selected,

temperature by pressing and holding down the

the display changes to that shown in Fig. 6 with the default temperature

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

TP75M 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

buttons. The unit will stay in frost

thermostat mode until the

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:

TEMPERATURE SETTING OVERRIDE

Press

to increase or

to decrease the current set temperature.

Each press will change the temperature setting by 0.5°C (or 1°F). To

make larger changes press the button and hold it down.

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.
