6.1 Group Objects
The group objects that are indicated with ‘(set)’ are write-only objects to control the ComfoConnect KNX C and/or
the ventilation unit. All other objects (without ‘(set)’) are read-only objects to retrieve the current value. The default
flags of the write-only objects are C-WTUI and the default flags for read-only objects are CR-T--.
When the I (Read On Init) flag is set, also set the T (Transmit) flag.

Description
Type2
Ventilation Preset1
�
0: Lowest ventilation preset; implies that Away function is enabled;
�
1, 2, 3: Ventilation preset; implies that Away function is disabled.

Ventilation Preset1 (set)
Ventilation Preset Away
Enabled/triggered when Ventilation Preset is (set to) 0.
1.001
1.017

Enabled/triggered when Ventilation Preset is (set to) 1.
Ventilation Preset 2
Enabled/triggered when Ventilation Preset is (set to) 2.
Ventilation Preset 3
Enabled/triggered when Ventilation Preset is (set to) 3.
Ventilation Preset Away (set)
Sets Ventilation Preset to 0.
1.001
1.017
Ventilation Preset 1 (set)
Sets Ventilation Preset to 1.
Ventilation Preset 2 (set)
Sets Ventilation Preset to 2.

Auto mode
�
Disable: Manual mode;
�
Enable: Auto mode.

Auto mode (set)
Temperature profile mode1
�
0: adaptive1;
�
1: fixed1;
�
2: use the External setpoint object to control the temperature setpoint of the ventilation unit,
instead of using the Temperature profile.
5.010
Temperature profile mode1
(set)
Temperature profile1
�
0: normal profile;
�
1: cool profile;
�
2: warm profile.
Setting the Temperature profile only has effect when Temperature profile mode is set to 0 or 1.
5.010
Temperature profile1 (set)
External setpoint
Temperature setpoint of the air within the building (=the temperature of the extract air or the value
measured by a room temperature sensor if available). The ventilation unit may preheat or temper
the air in order to reach the specified setpoint.
Setting the External setpoint only has effect when Temperature profile mode is set to 2.

Boost1
�
Off: normal;
�
On: boost enabled (implies that Ventilation Preset is 3).
1.001
Boost1 (set)
When triggered, Boost is enabled for the time specified by Boost time.
1.017
Boost time
Boost time in seconds.
The value 65535 s (about 18.2 hours) is interpreted as 24 hours. This object is only used to
configure the Boost upon triggering; it does not indicate the remaining time Boost is on.

Boost time (set)
Away function1
�
Off: implies a Ventilation preset of 1 or higher;
�
On: implies a Ventilation preset of 0, and ComfoCool is off.
1.001
Away function1 (set)
ComfoCool1
Off: the ComfoCool is always off, regardless of the required temperature setpoint;
On: let the ventilation unit decide whether the ComfoCool has to be enabled.
1.001
ComfoCool1 (set)
Standby
Off: normal operation;
On: the ventilation unit is in service mode; ventilation may be suspended.
1.001
ComfoHood1
Current state of the ComfoHood.
1.001
Airflow1
Reflects the supply air fan of the ventilation unit. (FAN_SUP)
