: Not to remove any zone valves or thermostats, I'd "slave" several zones to a master zone. Pick the two zones you want to control the circulator(s) and fire the boiler (pick the rooms that need the most heat). On all the others I would disconnect the contact relay that triggers the aquastat of the boiler.
: The "slave" zones can still open their zone valve, but have to wait for the "master" zone to trigger the circulator and boiler.
: With 7 zones, you probably have more then 1 circulator, so you have to figure out how the zones are related to a common supply header.
: But the nice thing about this set up, if a room is warm, it can't over heat. I also find that having the zone valve open without the circulator running still allows a small amount of heat to gravity flow into the zone. This prevents a zone from going through wide temp swings.
Thanks a lot, Joe! Is this something only a technician can do? Could you direct me to a web site (if any) to search the how-to?
