Group objects

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.

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 cooling mode or until the alarm is canceled by reception
of the value 0.
The operating mode is recalculated when changing to Heating mode. Heating can take place as nor-
mal, 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) deter-
mine the controller's setpoint 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).

This group object is enabled if the parameter Summer compensation in the Setpoint management parameter
window is parametrized with Yes.
This group object is hidden in actuator mode.
This group object receives the outside temperature so that the device can check whether or not summer
compensation must be active.
For this purpose, a starting temperature from which summer compensation must become active is set using
a parameter.
For a more detailed description of summer compensation:

This group object is enabled if the parameter Summer compensation in the Setpoint management parameter
window is parametrized with Yes.
This group object is hidden in actuator mode.
This group object indicates whether summer compensation is active.
