What is a room thermostat?

... An explanation for householders

A room thermostat simply switches the heating system on

and off as necessary. It 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.

Turning a 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 room thermostat to a lower setting will result

in the room being controlled at a lower temperature, and saves

energy.

The heating system will not work if a time switch or programmer

has switched it off.

The way to set and use your room thermostat is to find the

lowest temperature setting that you are comfortable with,

and then leave it alone to do its job. The best way to do this

is to set the room thermostat to a low temperature – say 18ºC

– and then turn it up by one degree each day until you are

comfortable with the temperature. You won’t have to adjust the

thermostat further. Any adjustment above this setting will waste

energy and cost you more money.

If your heating system is a boiler with radiators, there will

usually be only one 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.

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.

A demand for heat is

shown by a flame

symbol on the display,

i.e. the thermostat is

calling for heat to bring

the room up to or

maintain it at the

desired temperature.

During normal

operation the display

shows the actual room

temperature.

When the desired

temperature is being

adjusted the word 'SET'

is shown on the

FEATURES

This product has the following user adjustable settings

• Required room temperature (temperature setpoint)

• Preset temperature setting - Advanced feature

• Minimum & Maximum temperature settings -

Advanced feature

Simple Setting or Operating

To set the required room temperature

• The display normally shows the current room

temperature to within 0.5ºC

• To adjust the required temperature, turn the

dial clockwise to increase or anti-clockwise to

decrease, (1 click = 1ºC), the LCD will display

the temperature setpoint as it is being adjusted

and ‘SET’ will be displayed. After a few seconds

the display will return

to normal operation and

will display the actual room temperature.

While adjusting the temperature during normal

operation, when you reach the maximum or

minimum possible setting the display will flash to

indicate you cannot adjust the product further.

ADVANCED FEATURES

Adjusting the Setpoint using the Preset Temperature Mode

Change the temperature at the press of a button, for example, if

you are going out to the shops for an hour you can reduce the

temperature to save energy and then when you press the button

again on your return the setpoint will return to the previous level.

• To adjust the setpoint to the preset (or Setback) temperature,

press the ‘Set’ button during normal operation and the product

will go into Preset mode.

NB. This feature can be used to quickly adjust the temperature

setpoint to a setback temperature for economy operation if for

example, ‘Preset Temperature = 15

ºC’. Or alternatively to a comfort

setpoint if ‘Preset Temperature = 21

ºC’.

•

Once the setpoint has been changed to the preset (or setback)

temperature by pressing ‘Set’ the display will show the ‘Preset

Temperature’ and ‘SET’ will be flashing in the display as shown,

Location

Room Thermostat

1.

5m

Care should be taken to mount the thermostat in a position 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.

Signal Strength

Before fixing the Digistat+RF to the wall it is recommended to first

check the signal strength from that location.

To do this, remove the batteries, press and hold the ‘set’ button whilst

refitting the batteries, keep the ‘set’ button held and after a few

seconds the display will show ‘rF’ which indicates that the Digistat+RF

is continuously sending an OFF signal to the SCR (receiver). Leave the

Digistat+RF in position and return to view the SCR. If the red LED is

continuously flashing, this indicates a good signal. If the red LED is not

flashing, this indicates a poor signal and you need to reposition the

Digistat+RF until the red LED is flashing.

When the signal strength has been confirmed remove the batteries to

cancel the test and follow the installation instructions.

Before Installation

If you do not have the knowledge to install the thermostat safely then

you must arrange for a competent electrician to install it for you.

Wiring must conform to the current IEE regulations.

Prior to commencing the installation you must ensure the mains

supply is switched off.

Standard cable entry is from the rear, but if surface wiring, from the

top or bottom, is to be used, or extra space for cabling is required, use

the optional Pattress box (sold separately).
