TO THE BASE rFiu01
The leD on the base flashes in different ways depending on its operating / fault status:
1)
One short flash every 2 seconds means that the two units are communicating (section 17) and operating correctly
(normal operating status);
2) Two consecutive short flashes every 2 seconds means that the base is communicating with the climate controller in
radiofrequency (rF) but that Open Therm (OT) communication between the base and the boiler card is not working
properly (make sure the wires are correctly connected or replace the base or the boiler card);
3)
Three consecutive short flashes every 2 seconds means that the base is not connected (rF) with the climate con-
troller (see section 17.5);
4) One long flash means that one or more commands are being sent from the climate controller to the base;
5) Long repeated flashes every second means that the two units are trying to communicate (it may be necessary to
reset communication between the units by following the procedure described in section 17.4).
