RS-232
MODEL 8081 AND 8082 SUPPORT MODULES (OPTIONAL)
Support modules can be added if you require additional temperature or humidity values. Support modules can also be used for sensor averaging
in large areas.
Model 8081 Support Module
Provides two temperature values.
• One onboard or remote temperature sensor.
• One remote temperature sensor.
Use only the correct support module with each thermostat. Damage will occur if they are mixed.
8800s use only 8081 & 8082 support modules. 8870s use only 8061 & 8062 support modules.
WIRE NEEDED
• Multi-conductor thermostat cable (18–20 gauge).
• Category 5 communication wire (4 pair twisted cable).
WARNING
Model 8819 Distribution Panel
The distribution panel is a switch controlled
communication bus that can be wired to
eight Model 8800 thermostats. This allows
thermostat communication to be turned on
and off at one convenient location which
simplifies installation and troubleshooting.
Automation System Controller
RS-232 or RS-485 based automation system
controller such as the Aprilaire System
Controller.
Model 8082 Support Module
Provides one temperature and one humidity
value.
• One onboard humidity sensor.
• One onboard or remote temperature sensor.
