Zone Control

Two air conditioners on one roof, one thermostat on the wall. Coleman-Mach zone control runs each unit as its own zone from a single digital wall thermostat, with a zone control box in each ceiling assembly. The 9330A3341 single-zone digital stat and 9420A330 multi-zone stat are here with their matching control boxes; the pairings are specific, so use the upgrade kits or the compatibility chart.
