As you can see, at 06:30 , the heating will come on to raise the

temperature to 20ºC. At 08:30, the temperature set point is

dropped from 20ºC down to16ºC, it stays at 16ºC throughout the

day, until 16:30 when the temperature increases to 21ºC. The

temperature then drops down to a night-setback temperature of

7ºC until 06:30 when the cycle repeats for the next day

.

To adjust these times and temperatures

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 ‘Off

’ time

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 18

o

C,

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.

Y

ou may be able to temporarily adjust the heating programme, for

example, ‘Override’, ‘Advance’ or ‘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.

ow to replace the batteries see fig 3.

R

emove the battery cover using a coin. Replace the spent

batteries with 2 x 1.5V IEC LR6 (AA) Alkaline batteries ensuring

c

orrect orientation. Replace the battery cover pressing fully home.

(Fig 1) (Fig 2)

How do I know when to change the batteries.

When the batteries start to run low a battery icon will flash in the

display, to indicate “low battery” during this time the

Digistat +2RF

will function normally (see fig 1).

Please replace batteries with 2 x 1.5V IEC LR6 (AA) Alkaline batteries.

When the battery icon alone is shown in the display, the batteries

are completely exhausted and the

Digistat +2RF will cease to

function (see fig 2). Re-activate by replacing the batteries.
