DUCT SENSOR (P/N G100-71308305) - The 
thermostat is programmed from the factory to 
automatically recognize when a Duct Sensor is 
connected (step #10, page 13).
The Duct Sensor measures indoor air temperature 
and sends this information to the thermostat; it 
measures temperature with a range of 32˚ to 99˚  F. 
IMPORTANT:  Do not use shielded wire. Do not  
run sensor wiring in the same conduit as the 
24VAC thermostat wiring. Electrical interference   
may cause the sensor to give incorrect temperature readings.
See the Duct Sensor instructions for further details.
Note: If a Duct sensor is connected to this thermostat, then the fan should be 
programmed for continuous operation (step #5, page 11). This will provide 
airow over the Duct sensor and provide more accurate  
temperature readings.
