i have recently installed a new boiler the zone control is a taco though the name on it is opus this control will zone either zone valves or circulators.i have three zones plus the water tank all plumbed with circulators.i have the end switch on the relay attached to tt on a honeywell 7224u set to cold start . everything seems fine except the water heater zone keeps calling for heat . all my other zones work fine nd correctly according to amtrols directions my thermostat wire is hooked to tt on the zone control which it is am i missing something or is it wired incorrectly the tank is model ch-41zct has a built in thermostat on top of the tank with a apillary tube thanks in advance the opus control looks exactly like a regular taco switching relay except it can be wired for circ or zone valves
