Found this message that Peter (see below) posted back in 2001 and wanted to say a big thank you.
Not sure if you will see this Peter, but just like to say thanks very much for your post.
The batteries died on my wireless thermostat and there were no instructions or manuals from the previous owner of the property.
My system is labelled "British Gas WR1 Wireless System" which is the sensor by the boiler and the thermostat is labelled "British Gas RC1 Wireless System"
I came home last night at 00:30 and found the display had died and after spending 15mins working out how to replace the batteries l then spent till 2am browsing the web to find out how you get the two units to talk to one another. Random button pressing was not working!!!
My search proved in vain as l could not come up with any posts to do with RC1 or WR1. I went to bed with an extra duvet at that point.
At 7am this morning l just searched for "wireless system" AND "british gas" and your post came up.
Once again thanks it has been a life saver. Now l don't need to sit in a telephone queue to BG.

Receiver is the wall mounting Wireless Display is the remote thermostat
1. Make sure both battery compartments are out on the 'Wireless Display' and the screen has gone blank, takes about 2 mins to fade 2. Check that the receiver red LED is on 3. Push 'overide' button on the receiver once green LED should come on also 4. Push button 1 followed by 2 and hold them both depressed together Red LED will flash for 2 secs then go out (learn mode) 5. Release both buttons Red and Green LED should now both be on 6. Take the wireless display and hold it within sight of the receiver but more than one metre away 7. Push in the right hand drawer, then the left (it must be done in this order) The red LED on the receiver will flash for 7 secs and then go out. The green LED will remain on or off depending on the room temperature
If the red LED reamins on you need to repeat all of the above If it is still on something is wired incorrectly or broken
