3.13 Limit values for fan levels in CO2 and humidity lead calculation
The 3 fan levels are switched over 4 limit values.Fan level 1 is only activated when the limit value 2 is
reached, but the limit value 1 has to be fallen below again.The same applies accordingly to the higher
fan levels.If this or a higher fan level is already active, exceeding a limit has no effect.
3.14 Priorities of the used objects
The objects that influence the fan control have a order in which they are weighted. If in HVAC mode:
1. ) System lock ( Object-25 )
2. ) Supply air/exhaust air request ( Object-21 ) if supply/exhaust air request is active
3. ) Slave operation ( Object-26 ) wenn im Slave-Betrieb
4. ) HVAC mode manual operation ( Object-7 ) *
5. ) HVAC mode calculated from leads and set HVAC modes
6. ) HVAC mode 1 ( Object-3 ) *
7. ) HVAC mode 2 ( Object-4 ) *
