Cooling Status; Basic Load; Switchover Heating/Cooling - Busch-Jaeger mini KNX 6131/20 series Technical Manual

11.19.17 Cooling status

Number
17
The room temperature controller sends an ON telegram via the "Cooling status" object as soon
as it is active in the cooling mode. If the controller is in the inactive zone between heating and
cooling or is in heating mode, the room temperature controller transmits an OFF telegram on
the "Cooling status" object.

11.19.18 Basic load

Number
16
This object uses the value 1 to activate a parameterised base load, i.e. a minimum control value
greater than zero. The value 0 deactivates the base load. When the base load is deactivated,
the control value can be lowered all the way to zero if necessary when the setpoint temperature
is reached, despite the minimum value set in the parameter.
Note
Item 2:
Deactivating the base load for a floor heating system is always useful in the
summer, since it saves heating energy.

11.19.19 Switchover heating/cooling

Number
17
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.
