4.3.5. Hybrid operating mode
CAUTION
The hybrid operating mode is only available for appliances
with hydraulic back-up.
The appliance offers a choice between several hybrid operating
modes. The modes available offer either optimised energy
consumption according to energy cost, or optimised energy
consumption according to primary energy consumption. Both hybrid
operating modes are available via parameter U1. In optimised
primary energy consumption mode, the control system chooses the
generator that consumes the least primary energy. In optimised
energy cost mode, the control system chooses the cheapest
generator according to the coefficient of performance of the heat
pump and according to energy cost.
To access the parameters:
