   Do you know if it is possible to calibrate the Y87RF. It is reading about 2 or 3 degrees too high?
   I can do this with the radiator valves.

   Thanks

   Do you know what is the correct order to bind 11 x BD91’s and 11 x T87RF’s in 11 zones to an ATC928G3000? I think each BDR91 was linked to a T87RF which was linked to the ATC until some child who shall remain nameless managed to factory reset the ATC. Do I bind each 91 to it’s 87 and then link the 87 to the ATC or do I link the 87 to the ATC first and then link the 87 to the 91? The Honeywell instructions do not appear to be that clear.
