I need to know if this is a new installation or an existing one, and if this problem just began or not.
Its possible the wrong valves were selected if its a new system, or were wired incorrectly at the zone controller.
I need the brand and model number of the zone valves.
We can go from there without a time limit.
Thanks, ***** ***** valves come in several types, some are spring closed and power open, some are power open and power closed.
If you can tell me the model number of the zone valves I can look them up.
meantime tell me how many wires go to the zone valves, and if one of them is a ground wire or not.
Hello again, Honeywell makes a range of 4 wire zone control valves, I can probably search their manuals and from the many available, make a fairly accurate guess on what you have, but it would take a long time and could still be the wrong one, and all that time would be wasted.
Some 4 wire valves are power open, power closed, with a neutral, and a ground. Others spring closed, power open with an end switch that closes to all allow a boiler to start etc..
I need the model number on the valve... tomorrow will be OK if you cannot get to it tonight.
We can go from there
Good, type the model number here for me please.
Well, thats good work on your end, on this end, it is rare that one of my requests for information needed to help with a diagnosis solves the problem.
