7.5 CLIMATIC CURVE SETTING
Select the 'CURVE' screen to enable/disable (disabled by default) climatic offsetting with external temperature and
to set up the relevant operation parameters.
The offset curve establishes how the system flow temperature TM is corrected according to the external temperature TE.
NOTE:
The external temperature value TE is detected by the external units probe.
