12.7.4 Energy management
The energy effi ciency coeffi cient determines the switching point
between two energies (gas, electricity), in accordance with their
respective costs.
i The systempro makes a selection in accordance
with the energy effi ciency coeffi cient.An incorrect
setting will adversely affect the system effi ciency.
The adjustment requires certain information that can be easily
found in home owners energy bills (electricity and gas).
i Accurate price information is key to the correct
operation of the hybrid system. Always use the most
recent energy prices from your energy provider.
• Disregard the price of the fi rst energy tier for example, the
rate paid for the fi rst energy units used in a given billing
period. See example below.
• Depending on your installation, obtain:

• Now, on the same table, fi nd the price band that corresponds
to the gas price paid, and where the 2 intersect determines

i If the values you noted down do not correspond to
the values shown in the tables opposite, this means
that there is probably an error. Contact the energy
providers for confi rmation of prices excluding VAT.
