* The calculated value for standard exchange efficiency is displayed, so the indicated
temperature may differ from the actual SA temperature. If you want to display a value
that is closer to the actual temperature, perform exchange efficiency correction.
•
During By-pass operation, the temperature is not displayed for the RA and SA
(calculated value).
Note:
If a temperature display setting is set to OFF (not displayed) in the switch display settings of
the remote controller function selector, the temperature for that location is not displayed.
•
If the temperature sensor detection temperature becomes 40°C or more or -10°C
or less, the indications for both RA and OA become "- -", and the indication for SA
also becomes "- -".
•
If an error occurs, the correct temperature may not be displayed.
