Parameters
7.7.4.2.5 —
Dependent parameter
Base setpoint is
This parameter is only visible if the Setpoint specification and adjustment parameter has been
parameterized with the Relative option.
Options:
If the device has been configured only for the type of operation heating or the type of operation cooling,
the base setpoint is automatically the same as the Comfort setpoint for this stage and can also not be
changed.
This parameter is used to define which value corresponds to the base setpoint. It is possible to change
the setpoints parameterized for Comfort, Standby and Economy via the KNX bus using the base setpoint.
Depending on the option selected, the new base setpoint changes the value selected directly. All other
values are changed according to their relative distance from this value. The values parameterized are
overwritten with this change.
It is not possible to change the setpoints for frost protection and heat protection using the base setpoint.
If the basic-stage heating or the basic-stage cooling has been deactivated, the base setpoint is fixed to
the other comfort value for the existing type of operation.
