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 incre-
ments. Factory default is 0. This adjusted value will be used and displayed as actual tempera-
ture. 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 re-
quired.
