Digistat SCR

Wireless System

,OCATION

The Digistat SCR (receiver) should be mounted in a convenient
position, close to the 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.

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 wiring regulations.

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

%LECTRICAL

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.

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.
