About this deal

The receiver unit has 2 led lights on it. The top one should always be green. The lower one will turn amber when the thermostat talks to the receiver to turn the boiler on. When the amber light is on the boiler should be working. The receiver unit which is hardwired/connected to the boiler itself and this will be mounted close to the boiler (normally just under or to one side). If this does not work and you don't have a steady red light on the receiver unit then it has a fault, at the boiler you can disconnect the receiver unit wires and insulate with electrical tape, then put a direct link in between the two switch connections with one piece of wire, this will allow the timer control to be used until you can replace the faulty receiver If the top light is red there is a problem, normally for some reason the thermostat has lost its connection to the receiver.

Press & HOLD the ‘learn’ button for 2 seconds (a pen maybe required once more). The 2 units should now be synchronizing; this will take 10-30 seconds. Give it time and do not press anything. Using the small screwdriver Press and keep Pressed the LEARN button until the GREEN light starts to flash on the BR1. With the LEARN still pressed, press the SET button (Not the Reset) on the BR1 and the light should go solid GREEN. Here you go, NB: I've had bad units loose connection after 12 hrs again and again, its the unit if my reset procedure does not work, sorry but I made this fool proof, cheers DaveTurn the boiler off at the BOILER switch located on the BOILER and NOT the main power switch or you will turn the power off to the receiver also and you will fail. The Receiver (BR1) has lost communication with the Sender Unit (Thermostat). To re-establish communications carry out the following. Take the unit to the boiler and make sure the front switches on the thermostat unit are set to AUTO & RUN Dave’s idiot Guide to re-programming the Boss BPS242RF Room Thermostat and other make ones of the same type:

Fit new batteries to the thermostat 2 x AA (located at the bottom of the thermostat unit). Does it now work and is the TOP light on the receiver unit green? If yes ok, job done, if not continue down the list.Press and HOLD the top ‘override’ button and at the SAME time press and HOLD the bottom ‘Learn’ button. You may need a pen to push the small ‘Learn’ button in. KEEP BOTH HELD IN FOR 4 SECONDS and you will see the top led light flash, release both buttons.
