Fill level alarm
Channel – Controller 1 bit
DPT 1.005
C, W
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.
Note
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.

Outside temperature for sum-
mer compensation
Channel – Controller 2 bytes
DPT 9.001
C, W
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.

This group object is enabled if the parameter
Summer compensation
in the

window is parametrized with
Yes
.
This group object is hidden in actuator mode.
This group object indicates whether summer compensation is active.
