Trane TCON401AN21MA Comfort Control Features

Calibrate Outdoor Temperature

This option allows calibration (or deliberate miscalibration) of the outdoor temperature sensor. The selected number is number of degrees, plus or minus, which will be added to actual temperature. The number can range between + 5 and - 5 degrees in 1/2 degree increments. Factory default is 0. This adjusted value will be used and displayed as actual temperature. For example, if 2 is selected, 72 degrees actual will read 74 degrees.

Comfort Information Drawer

The drawer attached to the mounting base of the control is designed to provide a convenient location for the user to locate their local servicer. A standard business card can be folded and inserted into the slot on the drawer to remind the User whom to call when service is required.
