RC01=3, if the probe for disable heat recovery (configured as condensation
temperature or pressure) measures a value >= rC07 set, alarm occur.

The condensation pressure or temperature probe measures a value <=
rc07 set – rC08 differential

Heat recovery disabling function is intervened due to Par. rC09 time
expired.
