I have a Boss Therm BR1 receiver and a BPS242RF stat. The batteries fell out of the stat and now they will not communicate to each other. I have tried to reset them but this doesn't seem to make any difference. I cannot find the manual to how to rest them to speak to each other. The green light has gone off on the receiver and it flashes red for a few seconds when I press the set button, but that is it.
Remove the thermostat cover.
Then at receiver, press 'reset' for 4 secs. Then press 'set'
On thermostat press 'learn'.
The green light will flash, then go off, after 20 secs, it will illuminate. If it goes red, you have a fault. Hope this helps.
