Additional control unit (HPRA1)
4.3.1 Overview of factory-set parameter settings
All parameters of the auxiliary control unit (HPRA1) are described in detail in a tabular overview of this section with the factory
settings and setting areas.
CAUTION!
If the commissioning parameters BOH... and BUH... are configured in such a way that operation with the backup
heater and/or the booster request is possible, it must first be ensured that power consumption cannot exceed
the permitted supply load.
Current peaks that occur when a network in the power supply network of the domestic installation fails, it can
cause material damage to electrical current consumers.
