Q: I have a boiler heat system that use transformer and relays. always having trouble with the relays. is this something I can replace this old system with. currently I have five zones it would control.

Verified Reply- SupplyHouse StaffThis would be an option for a system using zone valves for zoning. If there are circulator pumps and switching relays in place, this would not be compatible.
