DuroZone 3 Zone Control Panel SMZ-3SW with Open/Close Switch for Each Zone 35227

Specifications

The SMZ-3SW is a simple zoning system incorporating individual thermostats and zone dampers to provide comfort and economy. The Zone 1 Thermostat has a Sub-Base which acts as the master control to determine if heating or cooling is desired and if the fan should be on constantly or just when the equipment calls. When all zones are satisfied, each zone damper will be in the position set by the Damper Switch. If any zone calls, that damper will open, or remain open and all others will close. Should another zone call, its corresponding damper will open. Upon satisfaction of the zone(s) all dampers will return to the position set with the Damper Switch.
