New advanced zoning control system using the EnviraCom communications protocol. 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 T8635L Microelectronic Communicating Programmable Thermostats.
• Expandable to nine zones with additional W8703 Damper Interface Modules and Thermostats.
• Compatible with conventional gas, oil, electric or heat pump systems up to 3H/2C.
• Unsurpassed ease-of-wiring with only three wires to connect between devices.
• True communicating system using standard thermostat wire.
• Networked zoning enables these features:
  • Time synchronization.
  • Shared-filter indication.
  • Outdoor temperature display in all zones with only one C7089B Outdoor Temperature Sensor connected.
  • Vacation 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.
  • 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.
  • Allows use of EnviraCom furnace board or traditional furnace boards.
  • Optional use of two transformers for power when many dampers are needed.
