ABB i-bus® KNX PARAMETERS
7.4.83 Minimum control value for basic load > 0
This parameter is used to define whether the basic load of the heating and cooling stages is always ac-
tive or whether it is activated via a group object.
More information: → ⁠ Basic load, Page ⁠⁠178 .
Note
The basic load is activated for all stages, but it applies only to the active operating mode ( Heating or
Cooling ). The basic load remains active during the operating mode change.
The basic load is set individually for each stage in the corresponding parameter windows → Parameter
Min. control value (basic load) .
Option
Activate via group object The basic load can be activated (1) or deactivated (0) via the group object Activate
minimum control value (basic load) .
The following dependent group objects are displayed:
•
Activate minimum control value (basic load)
Always active
The basic load is always active.

7.4.84 NTC type
This parameter is used to define the NTC type used.
Note
The resistance value of an NTC20 sensor is 20 kohm at 25 °C. The resistance value of NTC10 sensors is
10 kohm at 25 °C. The individual types differ in the further course of the resistance curves.
Option
NTC10-01 [-15…+100°C]
NTC10-02 [-15…+100°C]
NTC10-03 [-15…+100°C]
NTC20 [0…+100°C]
