Model 800 responds:
“Degrees Fahrenheit”
indicating Fahrenheit
scale is in effect.
NOTE
When switching from Fahrenheit to Celsius, or vice
versa, the change applies to all zones configured to
read temperature. When switching temperature scales
it is important to reset high and low temperature lim-
its on all temperature zones. Refer to Section 5.4.1 to
reset temperature limits.
5.6 Temperature Calibration
To compensate for minor variances in sensor accuracy, an offset
may be programmed for each temperature zone. The amount
of offset is measured in degrees Fahrenheit or degrees Celsius.
Adjustments are possible within a range from -10 degrees to +10
degrees. For example, if zone 3 is sensing temperature and is
reading 1 degree too high, then the calibration for zone 3 is set at
-1 to obtain an accurate reading.
