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.

ºc

• 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

ºc

temperature. If the radio signal has been successfully transmitted

and received, the red LED will ﬂash for 7 seconds then go off.

ºc

• If the red LED stays on, there may be some other fault that will

require the attention of a heating engineer/electrician.

ºc

Manual Overide

• The heating can be manually switched on and off by using the

3 0

ºc

ºc

'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.

TAMPER PROOFING (All Models)

ºc

To tamper proof the product i.e. prevent unauthorised adjustment of

the product set the Min and Max temperatures to the same desired

value.

FAULT DIAGNOSIS

If the display shows E1, the following faults could have occurred

p I

1. Internal temperature sensor has failed.

2. Ambient temperature is outside product operating temperature range.

E I

p I

If the display shows E2, the following faults could have occurred

1. External temperature sensor has failed.

E I

2. Ambient temperature is outside product operating temperature range.

3. External sensor has been wired incorrectly.

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.

p I

• After approx 30 days, a continuous battery symbol only will be

shown in the display and the unit will remain OFF.

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.

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).

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 pliers.

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 comply with current IEE regulations.

4. Place the SCR onto the wallplate and tighten the securing screws.

This product is double insulated and does not require an earth

connection. The SCR should be wired to the combi boiler or central

heating wiring using the correct type of cable or ﬂex. The SCR should

be wired in to replace hard wired room or programmable thermostats

shown on the system or boiler wiring diagrams. Always check other

manufacturers instructions for compatibility.

easily achieved by commissioning each Digistat and SCR in turn.

1. Install (see installation instructions) and turn power on to the

Digistat + RF

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

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

ºc

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

ºc

working.

13. Decrease the 'SET' temperature on the Digistat RF by rotating the

ºc

dial anticlockwise until the ﬂame symbol disappears.

14. The red LED on the SCR should ﬂash for 7 seconds. After 7

ºc

seconds both the red and green LEDs should go out. Check that

ºc

the boiler and/or motorised valve have powered down.

15. Place the Digistat RF in the chosen operating position, (see Digistat

ºc

i 0

ºc

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).

ºc

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

ºc

will occur approximately every 5 minutes.

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

ºc

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.
