One of my zones has 2 rads with HR92s but we've recently added some humongously thick curtains near the valves so I've put a Y87RF on the wall. I reset the Y87 binding, removed the "remote sensor" setting for the zone on the controller and bound the Y87 as a remote sensor. It seems to work but when the HR92 setting is adjusted (by turning the control on the top of it) the controller calls for heat. I'd expected the HR92 control to be redundant so I'm a bit confused. Is this "working as intended" or should I delete the zone and start again, binding the sensor before the valves?
