Hi folks, I was thinking about using a zone control module to run the 6 zone valves on our new gasifier system. Seems like a control module would make the wiring easy and trouble free on most of my zones, but I have 2 zones with special circumstances that I could use some help with. So here goes... 1) One zone requires a mixing valve... and thus requires an additional circulator after the valve that will need turned on and off with the opening and closing of the zone valve. What is the best way to achieve this? 2) Another zone is circulating water through an air handler, and is basically the same situation as the first zone... I need to be able to turn the blower on in the air handler when the zone valve opens... again... what is the best way to achieve this? I had thought I could just use switching relays connected to the "end switches" of the zone valves, as long as the end switches are dry contacts... and I think they are? They are Honeywell zone valves... Since I am using the zone control module, I shouldn't need the end switches on the zone valves to run the load circ right? That means I could use them to run the switching relays, right? thanks in advance for you help.
