6.3 Auto/Manual mode

The ventilation unit can be set to Auto mode, such that it determines the preset autonomously, or to Manual mode,
such that KNX gains more control over the ventilation units behaviour. 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 ComfoConnect KNX C will override any change.

Parameter
Type of Ventilation Preset objects
Limit of sending to Group Addresses (default:
600 telegrams per minute)
Unit of Temperature sensor/setpoint data
Unit of Airflow sensor data
Unit of Humidity sensor data
Number of bedrooms
Number of (habitable) rooms
Number of bathrooms
Auto mode disabled (KNX has full control)
When set, the Ventilation Preset of the ventilation unit
is changed.
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 ComfoConnect KNX C keeps enforcing the Away
function as set by KNX.
The ComfoConnect KNX C keeps enforcing the
ComfoCool setting as set 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, limit all updates to group addresses using
an average transmission rate. When 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 decreased, bus traffic by the unit is
kept low, at the expense of possibly higher latencies.
Enables all temperature-related objects that use °C, °F, K or a raw value
format.
Enables the Airflow object that uses either l/h, m3/h or a raw value format.
Enables all humidity-related objects that use a specific humidity format.
Enables the given number of CO 2 level bedroom sensor objects.
Enables the given number of CO 2 level room sensor objects.
Enables the given number of humidity level bathroom sensor objects.
Auto mode enabled
Setting the Ventilation Preset has no effect.
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.
