Summer compensation active
Output
Switching
This 1-bit communication object is used to indicate via the bus whether the summer
compensation is active (1) or inactive (0). If it is active, the setpoint value configured for the
cooling mode is increased by the summer compensation function. A decrease of the cooling
mode setpoint temperature below the value calculated by the parameterized summer
compensation function is not possible. An increase of the setpoint temperature for the cooling
mode is always possible.

Setpoint reached
Output
Switching
When the setpoint set on the device in comfort mode has been reached it is sent by means of
value (1) as information to the KNX bus via the 1-bit communication object. The function is
started by activating the comfort or presence mode. If the reaching of the setpoint temperature
is interfered with by the preselection of a different operating mode or by adjustment to a new
setpoint, value (0) is sent.

3. Fahrenheit (slave)
Input / output
Switching
The temperature indication on the display can be changed from Celsius (°C) to Fahrenheit (°F).
The conversion from Celsius to Fahrenheit always takes place in the display unit, since only
Celsius values are sent over the KNX bus. The value (0) results in a temperature indication in
Celsius, while the value (1) results in Fahrenheit.
Note
Item 2:
If the Fahrenheit object is active in the master/slave mode, the Fahrenheit (slave)
object must be connected to this object.
Item 3:
If the Fahrenheit object is active in the master/slave mode, the Fahrenheit
(master) object must be connected to this object.
