Continuous flashing for ten seconds – awaiting signal during commissioning procedure
Two Channel
One flash every six seconds – standby
One flash every second – communication lost (check batteries)
Two flashes every six seconds – CH demand
One long flash and one short flash every six seconds – DHW demand
Three flashes every six seconds – DHW and CH demand
Continuous flashing for ten seconds – awaiting signal during commissioning procedure

6. Button Functions
Battery Warning Symbol Fig 5
When the batteries in the transmitter are running low a battery symbol ( ) will appear on the display. If the batteries go completely flat then
the signal between the transmitter and the receiver will be lost and the receiver light will flash every second, this will cause the boiler to operate in
its last command state. e.g. if the heating is on when the signal is lost then the heating will remain on until the batteries are replaced.
