Warning
If you do not have the knowledge to install the Digistat+2
safely, arrange for a competent electrician to install it for you.
Wiring should conform to the current IEE wiring regulations.
Isolate mains supply before removing an existing room
thermostat and fitting Digistat+2.
Digistat+2 programmable room thermostats are double
insulated therefore Neutral and Earth connections are not
required. Unused existing cables should be safely insulated.
Location
Care should be taken to mount the
Digistat+2 on a wall, in a postion
which is not subject to direct
sunlight or draughts. Preferably it
should be mounted on an inside
wall about 1.5M (5ft) above the
floor in a position where it can
respond to room temperature but
away from the direct influence of radiators or other appliances
giving off heat.
Installation
1. Remove the front cover using a flat screwdriver and separate
from back plate (Fig 1).
2. Fix the back plate directly onto the wall using suitable wall
plugs and screws or mount over existing wall box (Fig 2).
3. Complete the wiring according to the connection suggestions
shown in (Fig 3). For Basic boiler, Combi boiler and Basic
boiler with zone valve applications Digistat+2 with battery or
mains supply are suitable.
For Electric Heat application use Digistat+2 with mains supply only
.
4. Replace the front cover by locating in position and pushing
fully onto the back cover (Fig 4).
5. Remove the battery cover using a coin (Fig 5). Battery model only.
6. Install the 2 AA batteries provided (Fig 6). Battery model only.
7. Replace battery cover (fig 7). Battery model only.
8. The Digistat+2 is now installed and will automatically start to
control the room temperature according to the pre-set
program 1 as shown in the User Guide.
The display shows the correct time and date which is
automatically set together with the actual room temperature.
Your Digistat+2 programmable room
thermostat. 24 Hour
Digistat+2 programmable room thermostat allows you to set
time and temperature periods (up to 6 per day) to suit your own
lifestyle. Once fully installed and powered the Digistat+2 will
automatically set the correct time and in auto mode will control
your heating system according to pre-set program 1 (9 till 5).
The temperature is controlled by sensing air temperature,
switching on the heating when the air temperature falls below
the thermostat setting and switching it off once this set
temperature has been reached.
(Fig 1)
(Fig 2)
How to change the temperature for a short time (Override).
When in Auto mode you can override the existing temperature
setting by pressing + or -. During adjustment the temperature will
flash then stop. The Digistat+2 will now control at this
temperature until the next programmed time/temperature event is
reached, when the Digistat+2 will revert back to Auto mode.
Whilst in temperature override the pointer indicates both Man and
Auto. To exit override press > to return to Auto. (Fig 1) shows
Digistat+2 in override.
How to set a constant room temperature (Manual mode).
Manual mode will allow you to set a temperature, over-riding all
programs, until you exit manual mode. In this mode all pre-set
time temperature events will be disabled.
To enter manual mode press < until the pointer indicates MAN
(Fig 2). The screen will only show the temperature, which can be
adjusted by pressing + or -.

How to set my room temperature for my holiday period.
(Holiday Mode)
When going on holiday you can lower the temperature of your
home for the duration of your holiday, but set Digistat+2 to
return to your normal programming ready for your return.
Holiday mode works by counting down the days or hour until
your return.
Time periods of between 1 to 24hr then 1 day to 199 days can
be set.
Example
I am ready to leave for my 2 week (14 day) holiday and would like
the house temperature held at a constant 10.0 ºC during this time
and on my return the house temperature will be already running
at my normal pre-set temperature.
To enter Holiday mode press the < button until the pointer is
indicating HOL (fig 3). The temperature will flash and by pressing
the + or - buttons you can change to the temperature required
(in this example to 10.0 ºC) (Fig 3a).
Then press < again to set the time period.(in this example 14
days) using the + or - buttons. (it would be advisable in this
example to set the time period 1 day less (13 days) to ensure the
house temperature is back to normal on your return). (Fig 3b)
Once you have set your time period the time will flash for 10
seconds and then start the holiday period. To exit the Holiday
mode press either < or > to return to auto mode.
When changing time the display will scroll through Hr (Hours)
1-24 then d (Days) 1-99.
The display will show holiday time period and set temperature.

What is a programmable room
thermostat?
...an explanation for householders
A programmable room thermostat is both a programmer
and a room thermostat. A programmer allows you to set
‘On’ and ‘Offtime periods to suit your own lifestyle. A room
thermostat works by sensing the air temperature, switching
on the heating when the air temperature falls below the
thermostat setting, and switching it off once this set
temperature has been reached.
So, a programmable room thermostat lets you choose what
times you want the heating to be on, and what temperature
it should reach while it is on. It will allow you to select
different temperatures in your home at different times of the
day (and days of the week) to meet your particular needs.
Turning a programmable room thermostat to a higher
setting will not make the room heat up any faster. How
quickly the room heats up depends on the design of the
heating system, for example, the size of boiler and radiators.
Neither does the setting affect how quickly the room cools
down. Turning a programmable room thermostat to a lower
setting will result in the room being controlled at a lower
temperature, and saves energy.
The way to set and use your programmable room
thermostat is to find the lowest temperature settings that
you are comfortable with at the different times you have
chosen, and then leave it alone to do its job. The best way to
do this is to set low temperatures first, say 18C, and then
turn them up by one degree each day until you are
comfortable with the temperatures. You won’t have to adjust
the thermostat further. Any adjustments above these settings
will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will
usually be only one programmable room thermostat to
control the whole house. But you can have different
temperatures in individual rooms by installing thermostatic
radiator valves (TRVs) on individual radiators. If you don’t
have TRVs, you should choose a temperature that is
reasonable for the whole house. If you do have TRVs, you can
choose a slightly higher setting to make sure that even the
coldest room is comfortable, then prevent any overheating in
other rooms by adjusting the TRVs.
The time on the programmer must be correct. Some types
have to be adjusted in spring and autumn at the changes
between Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating
programme, for example, ‘Override’, ‘Advanceor ‘Boost’.
These are explained in the manufacturer’s instructions.
Programmable room thermostats need a free flow of air to
sense the temperature, so they must not be covered by
curtains or blocked by furniture. Nearby electric fires,
televisions, wall or table lamps may prevent the thermostat
from working properly.
