it all depends on what kind of zones these are. if it is a boiler with 3 zones OK, but you need to be careful what kind of thermostat you use as some of those zone valves use close to an amp and some tstats cannot take that much. if it is a vav type zoning system it could be pretty bad to try and change them as a lot of those use a special tsat.
