Using the Temperature Display
In some circumstances, the temperature displayed on the
Home screen may not match the temperature near the
thermostat.
If your system is set up to use remote indoor sensors, it may be
reading a sensor in another location.
Temperature reading depends on location of sensor
Using the Humidity Display
In some circumstances, the humidity displayed on the Home
screen may not match humidity near the thermostat.
Some systems are set up to use two sensors, one to control
humidification, the other for dehumidification. These sensors
are often installed in different locations.

Depending on how your thermostat was installed, the
thermostat Home screen will display humidity readings from
only one sensor.
Humidity reading depends on location of sensor.
