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.

Stored programmes
MiStat P contains 3 pre-set programmes, as shown
below. These programs can be modifi ed according to
personal needs and can be stored by using a name. Via
this name they can also be re-loaded.
Once a programme has been modifi ed, the original
factory pre-set will no longer be available. On a System
Reset, only the current loaded programme will be
replaced with the factory setting – see Installation

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 fi nd 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 fi rst,
say 18°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.
You may be able to temporarily adjust the heating
programme, for example, ‘Override’, ‘Advance’ or
‘Boost’. These are explained in the manufacturer’s
instructions.
