Dehumidification Control
If the dehumidification control has been enabled, the communicating Comfort Control attempts to
control to this dehumidification setpoint by turning on the air conditioner. In extremely high humidity
conditions, Comfort Control keeps the air conditioner running for up to 3°F below your temperature
setpoint. It does this when trying to achieve your desired humidity setpoint and balance that with
your temperature setpoint.
NOTE: If auto changeover is selected, the deadband can be no closer than 5 degrees with
dehumidification enabled.
Trane Proprietary Humidity Control
When enabled, this feature will disable any blower off delays and disable continuous fan mode when
the indoor humidity is above the dehumidification setpoint. This will help prevent coil condensation
from being evaporated back into the air stream.

or frost can occur.
The degree of frost control is determined by the setting you choose between 0 and 10. Press More
key until you come to the frost setting screen. The display shows FROST and a number from 0 to 10.
When the factory setting (5) results in too much condensation or frost on the windows, lower the
setting. When the air seems too dry, raise the setting.

Temperature Recovery
Your Comfort Control comes with a feature called Adaptive Intelligent Recovery (AIR), which
eliminates all guesswork when setting your schedule. How long does it take the furnace to warm
your house in the morning before you get out of bed or how long does it take the air conditioner to
cool your house in the afternoon before you return from work? No problem. The Comfort Control
determines that for you.
Simply set your program schedule to the time you want the house to be at your comfort temperature.
The Comfort Control then turns on the heating or cooling at just the right time to have your home
reach your scheduled temperature at your scheduled time.
For example: you get out of bed at 6:00 AM and want the temperature to be 70°F (21.1°C). Set the
Wake period for 6:00 AM and 70
6:00 AM to raise the temperature to 70
0
F (21.1°C). The Comfort Control then turns on the heat before
0
F (21.1°C) by 6:00 AM.
The Comfort Control alerts you that the heating or cooling system is coming on before a scheduled
time by showing “Recovery” on the screen.

IMPORTANT
It takes about a week for the Comfort Control to adjust to local weather, your schedule, the
