This working mode is only enabled if the clock is present and enabled.
Set CF01=0, select air/air unit.
Set ES01-06, ES18-24 to enable the function automatic shutdown by RTC.
If a digital input is configured as Digital input working with supply fan only (DI type=92) and is active,
when current time is inside the automatic shutdown time band, the unit will work in "Ventilation only" mode.
In "Ventilation only" mode, only relay configured as supply fan is enabled.
After current time goes out of the automatic shutdown time band, the unit will back to normal working mode.
WARNING: In ventilation only mode, the supply fan will forced to active if unit is on. When the unit is placed
in remote off or stand-by, supply fan will switch off after the delay time set in par PA03.
