button until you return to
normal operating mode with
a display similar to the one
shown here.
OPERATING MODES
The Digistat can be operated in one of three modes.
1) Timed, all preset times and temperatures
2) Continuous night temperature (useful for low
limit temperature protection when on holiday)
3) Continuous ‘DAY 1’ temperature
Use the SELECT button to change the operating mode to
suit your requirements, the symbols are positioned on the
right hand side of the display.
TEMPERATURE OVERRIDE
If at anytime during normal operation, you wish to
temporarily increase or decrease the set temperature use
the + or buttons to change to your desired setting. This
can be done without entering the SET mode. Five seconds
after releasing the + or button the display will revert to
showing the actual room temperature. The Digistat will
now control the temperature to the override setting until
the next programmed switching time, when it will revert to
the times and temperatures you have already programmed.
BATTERY REPLACEMENT
30 days before the batteries need re-
placing, 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 12.00
midnight. The night setting can be programmed at whatever
time you require, even after 12.00 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 preset 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.

Digistat 3i
user instructions
The Digistat 3i features unique self learning optimum start
software. They can help achieve savings in excess of 10% on
heating costs and reduce CO2emissions, by delaying the start
time on milder days without affecting your comfort level.
USER INSTRUCTIONS FOR OPTIMUM
START
There is no extra programming involved. The self learning
software is factory preset and will start to monitor and adjust
the heating start times for setting , as soon as the unit is
installed.
The optimum start feature only operates on the first
switching time of each day ( ). Switching times
, and switch at the programmed times without any
delay.
The delay period can vary between 0 - 60 minutes
depending on:
a) The actual room temperature at the first switching time
( ).
b) The set temperature of the Digistat 3i.
c) The stored data on how fast the heating system
responded the previous day.
During normal operation the flame symbol on the
display indicates the current operating status.
Flame on = heating on
No flame = heating off
FIashing flame = saving energy (optimum start cycle

When the flame is flashing, the optimum start cycle can be
overriden by pressing the button once. This returns the
unit to normal operation.
