BATTERY REPLACEMENT
When the batteries approach the end of
their life, a battery symbol blinks in the
display (Fig.10.). When this symbol appears
both batteries should be replaced with high
quality alkaline cells. 15 days after the
battery symbol starts to blink, the thermostat
will switch off. While the battery symbol is
blinking the batteries may be changed
without loss of time or programme.
Have the new batteries unwrapped and ready, slide the battery
cover fully off to the left, remove the old batteries and insert the
new ones WITHIN ONE MINUTE. Replace and slide close the the
battery cover. The thermostat will continue to function according to
the automatic programme. Should the display ever go blank during
normal operation the batteries will need to be renewed, the unit
reset, and the time (and day) and programmes reset if required.
FACTORY PRE-SET PROGRAMMES

TYPICAL USER SET PROGRAMME
for models TP4 & TP5
This programme provides two
heating periods, morning and
evening and effectively
switches the heating off
during the day and overnight.
LIMITS OF ADJUSTMENT FOR TIME SETTINGS
Time setting 1 can be at any time of the day or night, but would
normally be in the morning.
Each of the time settings 2 to 6 can be at any time between the
proceding setting and 1.59am.
Time settings 2 to 5 can be set later than the next setting, but doing
this changes the next setting as well....
....E.g. changing setting 2 in any of the above to 3.00pm would also
change setting 3 and 4 to 3.00pm.
This feature prevents times being set out of sequence. If you wish to
return to the pre-set programme reset the unit as described above.
EVERYDAY OPERATION
When all six or twelve time/temperature settings have been checked
and/or altered, ensure the Programmable Room Thermostat is in
the RUN mode with the colon blinking (see Fig.1.) before sliding
the cover shut.
MANUAL OVERRIDE
If you wish to temporarily change the control
temperature from the automatic setting, there
is no need to re-programme the thermostat;
just press the up or down button until the
temperature you want is displayed. An up or
down arrow will appear in the display (Fig.9.)
to remind you that you have over-ridden the
programmed temperature. The unit will revert
to programmed temperature at the start of the next programmed
event.
CONSTANT LOW TEMPERATURE CONTROL
To set the thermosat to control at its low setting (5°C to 16°C
depending on model) for 24 hours a day press both
s
and
t
buttons
at the same time. The display will show the blinking colon, the low
setting and the snowflake symbol (fig 10). To return to the automatic
programme press the
s
and
t
buttons together again.
