Configuring a boiler not equipped with a room thermostat input
1. Set the following installer parameters on the boiler control panel:
Switch the boiler control system to 24h/24 comfort mode.
Heating set point temperature = Domestic hot water set point tem
pe 5°C.

10.5.6 Configuring the hybrid operating mode of a hydraulic
back-up
Important
Hybrid operating mode is only available for appliances with a hy
draulic back-up.
The hybrid function consists of an automatic switch between the heat
pump and the boiler, according to the cost, the consumption or emission of
CO
2
of each heat generator.
Tab.61 Calculating the threshold coefficient of performance
If the coefficient of performance of the heat pump is higher than the threshold coefficient of performance, the heat pump takes
priority. Otherwise only the boiler back-up is enabled. The heat pump coefficient of performance depends on the outside tem
perature and the heating water set point temperature.
HP061 parame

Description
HP061 = 1
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.
HP062: Energy cost in Hybrid Electricity cost in high tarif
HP063: Energy cost in Hybrid Electricity cost in low tarif
HP064: Cost of fossil energy (oil or gas) – price per m
3
or per litre – Can be set from 0.01 to 2.50 €/kWh
HP061 = 2
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 HP054 threshold coefficient of performance
value according to the primary energy consumption optimisation mode.
HP061 = 3
Optimisation of CO
2
emissions: The control system chooses the generator that emits the least CO
2
.
The switch between the heat pump and the boiler occurs at the threshold coefficient of performance value
calculated according to the CO
2
emissions optimisation mode:
HP065: Electrical CO2 emission in heating mode
HP066: Electrical CO2 emission in DHW mode
HP067: Gas or Oil CO2 emission
HP061 = 0
No optimisation: The heat pump always starts up first, regardless of the conditions. The boiler back-up
starts up afterwards, if required.
