I have a tenant with a good sized training room with three zones.
A 5 ton cooling only DX split system and three zone dampers. The system was controlled by an old Carrier Monitor master stat and two slave stats.(Master stat is belly up)
I am looking at replacing everything and installing three Distech EC-STAT-FC-AC and three Belimo modulating (0-10vdc) actuators. Do you see any problem with having the Fan / cooling output of all three stats controlling the same unit? basically a call for cooling on any one stat will bring on the unit or do I need to have a master stat?
