    When you do the RF test it always makes the light on all BDR91's flash together no matter whether you "test" the heating or hot water relays. It's just a quirk - our systems all do that too. So you...

    Yeah I've tried it on a stand closer to the boiler closet. It's not a signal strength or interference issue. No other devices on the system are affected including those in the same closet.
