Advanced zoning control system using the Enviracom™ communications proto- col. The most advanced and easiest to install zoning system in the industry. New control algorithm reduces and regulates plant cycles, decreases damper cycles and increases efficiency. Creates a networked zoning system when combined with three T8535L microelectronic communicating programmable thermostats. Expandable to nine zones with additional W8703 damper interface modules and thermostats. Compatible with conventional gas, oil, electric orh eat pump systems up to 3H/2C. Unsurpassed ease-of-wiring with only three wires to connect between devices. True comminicating system using standard thermostat wire.
• Time synchronization • Shared-filter indication
• Outdoor temperature display in all zones with only one (C7089) outdoor temperature sensor connected
• Vacaton Hold in all zones • Check LED in all zones • Auto-changeover by zone • Individual fan control in each zone
• Selectable high and low equipment protection settings • Adjustable stage timing • Adjustable purge timing and damper positions
• Expandable up to nine zones with W8703 Damper Interface Module
• Single network can use up to nine T8635L thermostats and two W8703 damper interface modules to control nine zones
• Telephone access when used with optional W8735B Telephone Access Modules
• Uses Zone of Greatest Demand intelligence
• Optional use of two transformers for power when many dampers are needed • Optional W8735A Serial Adapter provides home automation system interface
