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.
