Primary Energy
Optimisation of primary energy consumption: The control system chooses the generator that consumes the
least primary energy.
The switch between the heat pump and the boiler occurs at the value of the coefficient of performance
threshold COP Threshold(HP054) according to the primary energy consumption optimisation mode.
Hybrid Cost
Optimisation of energy costs for the consumer (factory setting): the control system chooses the cheapest
generator according to the coefficient of performance of the heat pump and according to energy cost.
The switch between the heat pump and the boiler occurs at the value of the threshold coefficient of per
formance calculated according to energy cost optimisation mode with the energy cost parameters.
Peak elec. cost (HP062): Energy cost in Peak rate electricity cost (in cents)
Off-peak elec. cost (HP063): Energy cost in Off-peak electricity cost (in cents)
Gas or oil cost (HP064): Cost of fossil energy (oil or gas) – price per m
0.01 to 2.50 €/kWh
Hybrid CO2
Optimisation of CO
The switch between the heat pump and the boiler occurs at the value of the coefficient of performance
threshold calculated according to the optimisation mode for CO
No Hybrid
No optimisation: The heat pump always starts up first, regardless of the conditions. The boiler back-up
starts up afterwards, if necessary.
