FEATURES
The 8081 TT/ 8082 TrH Support Modules are designed to work with the Model 8800 Universal Communicating Thermostat.
Up to four support modules per thermostat can be used to monitor temperature and/or humidity in various rooms or throughout
a larger area. The temperatures or humidity readings can also be averaged to create a controlling value for the thermostat.
MODEl 8081 TT OpTIONS
• 1 on board temperature sensor
• 1 on board and one remote temperature sensor*
• 1 remote temperature sensor*
• 2 remote temperature sensors*
* For remote temperature sensors use the Aprilaire Model 8051 Flush Mount Temperature Sensor, Model 8052 Duct/Outdoor
Temperature Sensor, or the Model 8053 Surface Mount Temperature Sensor.
