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.

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

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.

BATTERY REPLACEMENT (All Models)

• When the batteries are getting low (approx 30 days battery
life remaining) the battery symbol will flash in the display, it is
recommended to change the batteries during this period.

• After approx 30 days, a continuous battery symbol only

will be

shown in the display and the unit will remain OFF.

How to replace the batteries

Remove the battery compartment by pinching the tabs and
withdrawing downwards. Replace the spent batteries with 2 x AA 1.5V
alkaline batteries ensuring correct orientation. Replace the battery
compartment pressing fully home.

RF PRODUCT ONLY

SCR RECEIVER (RF Model only)

SCR (Receiver) Normal Operating Mode

• Once the ‘Wireless System’ has been commissioned, there should
be little need for any user interaction with the SCR.

• During normal operation the red and green LEDs will occasionally
be on, these signify the following;
Green LED
The green LED will be on when there is a demand for heating, and
off when there is no demand.
Red LED
The red LED will flash for 7 seconds, approximately every 5
minutes. This denotes that a radio signal is being received from
the Digistat+RF unit .

Situations Requiring Attention

Red LED continually flashing

• This denotes that the batteries in the Digistat+RF unit are
approaching the end of their life (see ‘battery replacement’).

Red LED continually on

• This denotes that the SCR has been unable to receive a radio
signal from the Digistat+RF unit. This may be caused by the
batteries being dead (see ‘battery replacement’) or some
temporary interference with the radio signal.

• To resend and test the signal, go to the Digistat+RF unit and open
the battery drawer, after a few seconds (the display will go blank)
close the battery drawer and then reset to your desired
temperature. If the radio signal has been successfully transmitted
and received, the red LED will flash for 7 seconds then go off.

• If the red LED stays on, there may be some other fault that will
require the attention of a heating engineer/electrician.

Manual Overide

• The heating can be manually switched on and off by using the
‘OVERRIDE’ button on the SCR in a fault situation, even though
the red LED will stay on until a satisfactory signal is reinstated.

• Once the SCR receives a satisfactory signal again, it will
automatically reset itself for normal operation.

COMMISSIONING THE ‘WIRELESS SYSTEM’ (RF Models only)
Standard for all models

IMPORTANT: MULTIZONE INSTALLATIONS ONLY
If more than one ‘wireless system’ is fitted within the same property.
ie. for controlling 2 or more zones (multi-zone) it is essential that the
Digistat RF units are matched correctly to the relevant SCR. This is
easily achieved by commissioning each Digistat and SCR in turn.

1. Install (see installation instructions) and turn power on to the
SCR (receiver). If a separate programmer is fitted, ensure that it is
switched on. The red LED should come on.

2. Push the ‘override’ button on the SCR once. The green LED should
also come on. Check to see if the boiler and/or motorised valve
are working.

3. To enter ‘learn’ mode push the button marked 1 followed by 2
(OVERRIDE) and hold both depressed together. The red LED
should flash for 2 seconds and then go out signifying the SCR is in
learn mode. Release both buttons.

4. The

red and green LED’s should both now be on.

5. Take the Digistat RF and hold it within sight of the SCR (no closer
than one metre).

6. Insert the batteries into the holder and slide them into the Digistat
RF until the drawer clicks into place.

7. The Digistat RF should now display the actual room temperat

ure.

If the unit has been stored in a cold place

, it may take time to

warm up.

8. As soon as the battery compartment is slid back into place, the
red LED on the SCR should flash for 7 seconds and then go out.
The green LED may be on or off depending on th

e room

temperature at the time of commissioning.

9. If the red LED remains on, slide down the battery drawer on the
Digistat RF, check the battery positions are correct, and once

the

display

has faded, repeat steps 6 to 8.

10. Increase the ‘SET’ temperat

ure on the Digistat RF by rotating the
dial clockwise until a flame symbol appears, in the left hand
segment of the display.

11. The red LED on the SCR should flash for 7 seconds. This confirms
that the radio signal is being sent and received. After 7 seconds
the red LED should go out and t

he green one come on.

12. Check to confirm that the boiler and/or motorised valves are
working.

13. De

crease the ‘SET’ temperature on the Digistat RF by rotating the

dial anticlockwise until the fla

me symbol disappears.

14. The red LED on the SCR should flash for 7 seconds. After 7
seconds both the red and green LEDs should go out. Check that
the boiler and/or motorised valve have powered

down.

15. Place the Digistat RF in the chosen operating position, (see Digistat
RF location section) and repeat steps 10 to 14. Once you have
confirmed the system operates correctly, fit and secure the
Digistat

RF to the wall (see installation instructions).

During normal operation the red LED on the SCR will flash for 7
seconds each time a radio signal is received from the Digistat RF. This
will occur approximately every 5 minutes.

The green LED on the SCR denotes a call for heat (ON).

Once the system has been successfully commissioned, buttons 1
and 2 on the SCR should not be pressed simultaneously, unless a
replacement Digistat RF or SCR is fitted.

OVERRIDE

LEARN
MODE

If you do not have the knowledge to install the SCR 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.

Installation Instructions

Read all installation and commissioning ins

tructions before
proceeding.
Do not switch on until ready to commission.

The system wiring must be able to be fully disconnected from the
mains supply by a switch incorporated in the fixed wiring having a
contact separation of at least 3mm on both poles. Fused at 3A.

Location

The Digistat SCR (receiver) should be mounted in a convenient
position, close to the combi boiler or central heating system wiring
centre. (Care should be taken not to mount the SCR in a position
where it is surrounded by metal objects or mains voltage cable, as this
may interfere with the radio signal).

For the best performance install in an open space, at least 30cm
distance from any metal objects including wall boxes and boiler
housing.

It is recommended that the SCR is mounted on the wall nearest the
final location of the Digistat +RF room thermostat and not less than
30cm from the boiler side panel.

Warning: Installing the SCR too close to the metal side panel or
mains cables may interfere with the radio signal.

Fixing (minimum wall plate clearances shown)

1. Loosen the securing screws, remove the wallplate, and if surface
wiring is to be used, snap out the cable entry strip on the bottom
edge of the wallplate with a pair of pli

ers.

2. Fix the wallplate, terminals at the top, either direct onto the flat
wall using wall plugs and no 6 x1” wood screws or on a flush
mounting single conduit box using M3.5 x 14 screws. Minimum
wallplate clearances are shown.

3. Complete the wiring to the SCR wallplate in accordance with the
relevant diagram, to com

ply with current IEE regulations.

4. Place th

e SCR onto the wallplate and tighten the securing screws.
