5.4 Operating mode settings
The settings for the operating modes define the specific settings for the
supply and
exhaust fans
for all operating modes and for the speed, flow and pressure control
strategies. These settings are configured by the installer. The end user has no
option to change the values for the operating modes.
For Comfort, Economy and Unoccupied modes, dedicated settings for
relative
humidity (r.H.), air quality (AQ) and temperature
can be defined.
The temporaty operating modes Fan boost, Fire place and Kitchen hood have no
dedicated r.H., AQ and temperature settings. For these modes, the settings for
Economy mode apply.
