Group objects
No.

This group object is enabled if the parameter Fill level sensor input is set to Via group object in the Application parameters
parameter window.
The device must be parametrized for cooling or heating mode for this parameter to be visible.
This group object is hidden in actuator mode.
This group object can receive the fill level status via KNX.
Telegram value:
•
0: Fill level alarm inactive
•
1: Fill level alarm active
When the fill level alarm information is received, this group object changes the device's operating mode to heat protection
to protect the building.
The fill level alarm message means that the fill level in the condensate tray has exceeded a predefined limit.
More condensate formation would cause the condensate tray to overflow and thereby damage the building.
The alarm is valid as long as the device is in the cooling type of operation or until the alarm is canceled by reception of the
value 0.
The operating mode is recalculated when changing to heating type of operation. Heating can take place as normal, because
the dew point is not a problem during heating.
A higher-priority group object can override the operating mode.
The group objects and states Override mode, Fill level alarm, Dew point alarm, Window contact, Request On/Off (Master),
Presence detector and Operating mode (listed in decreasing priority) determine the controller's setpoint temperature
in addition to manual setpoint adjustment and basic setpoint adaptation.
If a slave is used:
To indicate the operating mode on a slave, the group address associated with this group object must also be connected
to the slave's group object Dew point alarm (slave).
