6.3 Auto/Manual mode

In the most common scenario in which the KNX system determines the ventilation speed, the Manual Mode must be
selected (Auto Mode: off). It is also possible to use the KNX system to monitor the ventilation unit. In this case the
Auto Mode must be activated. Enabling or disabling Auto mode influences other group objects as specified in the
table below. Group objects that are not mentioned in the table below, behave identically regardless whether Auto
mode is set or not. Whether Auto mode is enabled or not, cannot be configured on the ventilation unit; the setting
in KNX determines the operation of the device.

The Ventilation Preset of the ventilation unit is
determined by KNX.
When Boost is turned on by the ventilation unit, but it
was not requested by KNX, the ComfoConnect KNX
C will force it off again. However, when KNX triggered
Boost, the ventilation unit decides when to turn off
Boost again (usually when the Boost time expires).
When the Boost time is changed by the ventilation unit,
the ComfoConnect KNX C resets it to the value given
by KNX.
The Away function is determined by KNX.
The ComfoCool setting is determined by KNX.
When Away mode is disabled, Boost is triggered when
the ComfoHood is on. The Boost time is taken into
account when the ComfoHood is turned off.
Description
This parameter enables either the switch or trigger Ventilation Preset
group objects. Choose either type that matches your KNX application.
To prevent bus overload, this parameter sets the number of updates per
minute to group addresses using an average transmission rate. If the value
is increased, the ComfoConnect KNX C (and therefore the ventilation unit)
may have a lower latency in updating group objects, but may overload
the bus when there is already high traffic. When the value is lowered, bus
traffic by the unit is kept low, at the expense of possibly higher latencies.
This parameter sets the unit used for the temperature: °C, °F, K or a raw
value format.
This parameter sets the unit used for the air flow: l/h, m3/h or a raw value
format.
This parameter sets the unit used for the humidity.

Setting the Ventilation Preset has no effect.
KNX is only monitoring, while the airflow follows the
programmed ventilation schedule.
Boost can be turned on and off by the ventilation unit.
The Boost time can be set on/by the ventilation unit.
When it is set, it communicates to KNX.
The ventilation unit may switch on or off the Away
function by itself, depending on its schedule, for
example.
The ventilation unit may switch on or off the
ComfoCool by itself, depending on its schedule, for
example.
Let the ventilation unit decide how to handle the
ComfoHood with respect to Boost.
