Zone valve wiring diagram - We consist of wiring diagrams and set up instructions for maximum region valve model and multi-area controllers, and we describe special wiring problems that could occur if you blend different sorts, manufacturers, or models of heating quarter valves on the identical hydronic heating (warm water heating) machine. My unpleasant difficult caricature above on thi spage desires to be re-drawn neatly, however there i display how we efficaciously stressed-up a blended logo sector valve installation. I had honeywell zone valves and one white rogers region valve. [Click to enlarge any image]. A few years back i converted about 1/4-1/three or my residence into hydronic radiant ground warmness running off equal region as the baseboard. The man who sweated the tubes and zoned it out has never come lower back to hook up the zone controller. On most u.S. Systems the circulator runs sending water via the open area loops and a number one manage at the boiler, monitoring water temperature, sincerely turns the boiler on or off as needed to re-warmness the water. In addition on your manage, the honeywell l6006c 1010, honeywell's l8124a,c and 8151a are triple aquastats similar in function, regularly used to manipulate region valves. In which you could run into hassle is with an set up that has a mixture of various manufacturers of sector valves. In that case, the wiring commands for one employer can be unique from the opposite. Once i got into that trouble years ago i was wiring up a honeywell area valve to a system already the use of aptitude quarter valves. I called my heating supplier who had dave ferris (now retired) on deck to answer wiring questions.
To control up to eight heating zones you would possibly cord a couple of preferred switching relays together as shown in this taco wiring diagram. This example is from the taco sr503-4 switching relay practise sheet whose link is given above. [Click to enlarge any image]. Properly wired, the individual thermostat calls for warmth, the quarter valve opens, while the valve is absolutely open an give up switch inside the valve connects a second pair of wires that switch on the circulator pump lower back on the boiler.
