ROOM TEMPERATURE OFFSET
This option allows calibration (or deliberate miscalibration) of room
temperature sensor. There are various reasons why the home owners
want to adjust the displayed temperature. The selected number is the
number of degrees, plus or minus, which will be added to the actual
temperature. The number can range between -5 and +5. Factory default is
0. This adjusted value will be used as actual temperature for both display
and control action. For example, if 2 is selected, 72F actual will read 74F.
If setpoint is 72, the room will control to an actual value of 70 which will be
displayed and acted upon as if it were 72. The effect is that a positive
number selection will make the room temperature lower and vice versa.
This thermostat is factory calibrated within an accuracy of plus or minus
1F, so this adjustment will provide the best accuracy when set to 0.
