DIGISTAT+, DIGISTAT+RF

ROOM UNIT

Power Supply: 2 x AA Size, 1.5V alkaline batteries

Switch Type & Rating:

Relay version: SPDT 2(1)A 12-240V AC(DC) Volt free

Radio frequency:

RF version: 433 MHz

Radio Signal Range: 30m typically. The range may be affected by

(RF Version) the composition / density and number of

walls between the Digistat RF and SCR.

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.

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.

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.

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 instructions 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.

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 temperature.

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 the 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’ temperature 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 the green one come on.

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

13. Decrease the ‘SET’ temperature on the Digistat RF by rotating the dial anticlockwise until the flame 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.
