DetailsSMZ-4SW 4 Zone Control Panel provides the contractor with a simple, low-cost zoning system for 4 zones. SMZ-4SW Panels allow for the use of a switchable sub-base (must have B & O terminals) in zone 1 to act as the system's master switch for heat, cool and fan. Moving the fan switch on the zone 1 thermostat sub-base to "ON" will activate the fan to enhance air circulation.
All SMZ Zone Systems are equipped with individual zone damper control switches. These switches will allow a zone damper to remain in either open or closed position when the system board is at rest. By setting the switches, the installer or home owner can choose the position of his system's dampers, to inhibit migration of air into spaces not desired, for seasonal purposes, or when a zone is not in use.
