W8703A

 Damper Interface Module

APPLICATION

The W8703A Damper Interface Module (DIM) controls 

up to three conventional zone dampers when used with 
T8635L Microelectronic Communicating Programmable 

Thermostats and the W8635 Equipment Interface 
Module, Table 1. The W8703A uses Enviracom, a low-

cost wired communications protocol.

Using the W8703A Damper Interface Module with up to 
three T8635L Microelectronic Communicating Program-

mable Thermostats and a W8635A,B Equipment 
Interface Module enables the following 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 (when used with the 

W8635B Equipment Interface Module for heat 
pumps).

• System switch setting automatically changes in all 

zones.

• Individual fan control in each zone.

NOTES:

Up to three T8635 Thermostats can be con-

trolled with the W8703A Damper Interface 
Module. 

Up to six zones can be controlled using two 
W8703A and up to nine zones can be con-

trolled using three W8703A.
