Fig. 38. Calibration Page
The following is a description for each of the fields.
MEASURED VALUE:
This is the actual value of space temperature read by the controller.
This is inclusive of any calibration offsets that a particular controller
applies to the actual value read.
EXPECTED VALUE:
Takes the user input value as the true value the sensor should be
detecting.
CALCULATED OFFSET:
Displays the difference between the actual and edit value.
CALIBRATE:
Enter the user input value for the temperature and click and Calibrate
button. The Space Temperature is calibrated to the value entered by
the user. The space temperature can be calibrated to a minimum of –
4 deg F( -2.2 deg C) and to a maximum of 3 deg F(1.7 deg C). If the
user enters out-of-range values, TStatSpec
™ warns about the above
limits and calibrates to the nearest valid offset value.
REFRESH:
Click on this button to refresh the temperature values.
CLOSE:
Closes the calibration screen.
HELP:
Click on this button to display help.
NOTE: When the space temperature is calibrated, it causes
a change in the configuration and the configuration
ID. It is a good idea to get the configuration ID again
from TStatSpec™ configuration screens and input
the it into the thermostat.
T7350 Diagnostics
Description:

diagnostic mode and checked for proper operation. This
operation forces the outputs to manual mode and checks their
operation. In this mode, the controller outputs are not driven
