Can anyone confirm the correct wiring needed to fit 2x BDR91 receivers?
I have a Y plan system with a Gloworm 12HXI boiler, a Grasslin Towerchron QE2 programmer in the kitchen and a thermostat in the hall.
From what I can gather, 1 is HW off, 3 is HW on and 4 is CH On on the current programmer.
Thanks for the quick reply. I think I'll go for the Hot Water Kit too then, I just didn't see much of a use for it (aside from seeing the tank temp on the controller).
I've been considering a Honeywell Evohome controller but I have a Y plan system.
This means I would I need to add the "Hot Water Kit" (which uses a battery operated cylinder thermostat). I don't really want this and I'm happy to run my existing programmer on a regular timed program if...
