Deactivating the basic load for a floor heating system is always useful in the summer,
since it saves heating energy.
12.35.19 Setting of basic load – Combined heating and cooling mode - Object no
Object name Data type Flags
Switchover heating / cooling
1 bit DPT 1.001
C, T
1. Automatic: If the switchover between heating and cooling is performed automatically
by the room temperature controller, then this object is used to provide information on the
current heating (0) or cooling (1) status to the KNX bus. It is a transmitting object.
2. Only via object: The switchover between heating and cooling on the room temperature
controller occurs solely via this 1-bit communication object. The value (0) activates the
heating mode, and the value (1) activates the cooling mode. This is a receiving object.
3. Manual or via object: The switchover between heating and cooling on the room
temperature controller occurs by user interaction or via the 1-bit communication object.
The information on the respective heating (0) or cooling (1) status is available to the KNX
bus. This is a receiving and sending object.
12.35.20 Setpoint Setting – Object no
Object name Data type Flags
Actual setpoint
2 byte DPT 9.001
C, T
The object outputs the current setpoint temperature resulting from the following: the
parameterized setpoint temperature of the current operation type and operating mode,
the manual setpoint temperature adjustment, a change in the base setpoint temperature
via the base setpoint value object. This is purely a transmitting object.
12.35.21 Changing set values – Object no
Object name Data type Flags
Resetting manual setpoints 1 bit DPT 1.001 C, W, U
This 1-bit communication object is use to reset the manual setpoint adjustment that was
set on the device.
12.35.22 Temperature reading – Actual temperature - Object no
Object name Data type Flags
Actual temperature 2 byte DPT 9.001 C, T
Actual temperature weighted
2
byte DPT 9.001
C, T
Item1: The object outputs the measured (room) temperature, adjusted by the calibration
value.
Item 2: The object outputs the temperature value, which is calculate from the recording
and weighting of internal and up to two external temperatures.
