BATTERY REPLACEMENT
30 days before the batteries need
replacing, a battery symbol will flash in
the right hand side of the display,
(Diagram C). This signifies that two
1.5V type AA
alkaline batteries
will be needed to replace the existing
ones. If battery replacement is carried out in this condition
the programmed settings will only be held in the memory for
a maximum of one minute, after which re-programming may
be necessary.
IMPORTANT
To avoid the possibility of having to
re-programme the switching times
and temperatures, it is advisable to
wait until the display with a flashing
battery symbol changes to a
continuous battery only display
(after 30 days – Diagram D). In this condition the unit will
remain OFF but your programmed settings will be held in
memory for a number of weeks. The battery compartment
can now be left open, to replace the batteries, for
approximately one hour. If the compartment is left open for
longer, the unit will revert to the factory preset times and
temperatures. It may be necessary to reset the correct time
of day after changing the batteries.
The battery compartment is situated at the bottom of the
unit (press to unlatch and slide down). Ensure new batteries
are installed correctly.
HELPFUL HINTS
1) First/last set times
The Day 1 setting cannot be programmed before
12.00am. The night setting can be programmed at
whatever time you require, even after 12.00 am (midnight) so
long as it is not programmed more than 23 hours 50 minutes
after the Day 1 setting.
2) Part or full day omission
If during programming the Digistat, one of the symbols on the
left hand side of the screen starts to flash, this indicates that
two or more of the switching times have been set to the
same time. This facility enables you to omit one or more of the
switched periods. When one or more switching times are
programmed together the later setting takes precedent. For
example, if all four switching times were set together the
Digistat would control continuously at the fourth (night)
temperature setting .
3) Programme sequence
The Digistat will not allow you to program the switched
periods out of sequence but will hold the times together as
stated above.
4) Reset
If at any time during the programming you get confused and
would like to start the procedure from the beginning press the
SELECT and – buttons at the same time and hold for two
seconds. This resets the Digistat to the factory pre-set times
and temperatures shown in the table (overleaf).
5) Self revert
If during programming no button is pressed for between one
and two minutes the Digistat will revert automatically to its
normal operating mode.
