    Controlling a BDR91 from two CM28

    I'd like to have thermostats (T87?) in two different rooms control the same BDR91 - is this possible?

    Also, I have 2 controllers bound to 1 BDR91 but I don't know how it was done - can anyone enlighten me?

          I've got towel rails in 2 bathrooms connected to a zone valve and timer. I was thinking of using two wall-mounted thermostats, combined into a single zone, to drive a single BDR91 controlling the ZV. Alternatively, each thermostat in its own zone but driving the same BDR91. It's possible to connect 2 controllers to the same BDR91 (although I don't know how to do it .. ?) so I thought it should be possible. I guess I could put HR92s on each towel rail but I didn't want more whirring.

            A single BDR91 can be bound to 4 devices. So it is possible.

              Thanks for the info, I'd be interested to know where you found it. Also, does binding to multiple devices require any "special" actions?

                Just keeping binding as normal but just dont put the BDR91 into a clear previous bindings mode. See the instructions for the BDR91.
