OPTION 13 -- ROOM TEMPERATURE OFFSET
This option allows calibration (or deliberate miscalibration) of
room temperature sensor. There are various reasons why the home
owner may want to have displayed temperature adjusted to a
higher or lower value. 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,
72_F/22_C actual will read 74_F/23_C. If setpoint is 72_F/22_C,
the room will control to an actual value of 70_F/21_C which will
be displayed and acted upon as if it were 72_F/22_C. The effect is
that a positive number selection will make the room temperature
lower and vice versa.
