Wiring Taco zone valves and circs
I have 5 zones of HW. 2 zones have zone valves the other 3 zones are circs. The ZVC control board will only connect zone valves and the one circ used in connection to the ZV's. The other 3 zones looks like I need a separate SR-4 for the circs.
I was wondering how I could wire this using one board. Does the Taco make a board that incorporates Zone valves and circs together without having to buy 2 control boards?
