sensor, the thermostat internal sensor is not used.

ONE REMOTE INDOOR SENSOR INSTALLED
If one remote indoor temperature sensor is used, the screen 

showing the Inside temperature reading displays the 

temperature at the indoor remote sensor location.

MULTIPLE REMOTE INDOOR SENSORS INSTALLED
If more than one remote indoor sensor is used, the screen 

showing the Inside temperature reading displays the average 

of all the remote indoor sensors.

Portions of the touch screen interface can be fully or partially 

locked. See the Advanced Settings section for information to 

use these features. When the thermostat displays LOCKED,
