Sensor Offset Adjustment (So) Sensor offset allows you to compensate for any difference between the displayed
temperature value and the temperature sensed at the A99 sensor. Select a temperature value to offset the
temperature displayed on the LCD from the temperature sensed at the sensor. The sensor offset adjustment range is
from -5°F to 5°F (-3°C to 3°C) in 1° increments.
•
Backlight Brightness Level (bLL) The backlight brightness level feature allows you to adjust the LCD backlight intensity.
At level 0 the backlight is off. Level 10 is the brightest backlight setting and the system default. The selected backlight
brightness level is applied to the LCD during normal operation. When you enter the programming menus to set up the
control or press any key, the LCD automatically goes to the brightest level. If you do not press a key for 30 seconds, the
main screen displays and the backlight setting reverts to the selected brightness level.
