Fan coil setting – Fan speed level – Fan coil step status - Object no
Object name
Data type
Flags
Fan coil step status
1 byte DPT 5.001
C, W, T, U
Using the "Fan coil step status" object, the room temperature controller receives the
current fan speed level of the fan coil actuator.

Summer compensation – Outside temperature for summer compensation -

Outside temperature for
summer compensation
2 byte DPT 9.001
C, W, T, U
In order to save energy, and to ensure that the temperature difference occurring during
entry and exit of a climate-controlled building stays within comfortable limits, the reduction
of room temperature by cooling devices should be limited as a function of the outside
temperature (summer compensation). This, for example, prevents the air-conditioning
system from further reducing the room temperature to 24°C with an outside temperature
of 35°C. This function can only be used with an outside temperature sensor. This 2-byte
communication object must then be used to provide the controller with the current outside
temperature.

Summer compensation –Summer compensation active - Object no
Object name
Data type
Flags
Summer compensation
active
1 bit DPT 1.001
C, T
This 1-bit communication object is use 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 increase 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.

Slave – General – on/off request - Object no
Object name
Data type
Flags
On/Off request – (master)
1 bit DPT 1.001
C, W, U
On/Off request – (slave)
1 bit DPT 1.001
C, T
This 1-bit communication object must be connected to the respective slave
communication object in order to synchronize the devices in the master/slave
configuration.
