This thermostat is wired up to a 3 zone gas heated furnace hot water baseboard.The thermostat works the way it schould on one zone,but I am having problems on the other 2 zones because the way I have it wired up if the thermostat is set on a.c. you can go over to the 2 other thermostats and still turn on the heat.The folling terminals are wired as followed R-power from 24volt transformer,w-to zone valve,RC-second transormer power,Y-cool relay,G-fan relay.(The A.C. is a total independent system).When looking at the schematic it says the B terminal schould be an aux. contact,but I have no voltage on it.Any help would be appreciated,Thankyou
