The energy efciency coef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 efciency coefcient.An incorrect
setting will adversely affect the system ef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 rst energy tier for example, the
rate paid for the rst energy units used in a given billing
period. See example below.
• Depending on your installation, obtain:
- the price exc VAT per kWh for electricity and natural gas,
- the price exc VAT per ton of propane gas.
- the price exc VAT per litre of heating oil.

• Choose the table corresponding to the type of gas used by
your installation.
• Look for the column which corresponds to the price paid for

• Now, on the same table, nd the price band that corresponds
to the gas price paid, and where the 2 intersect determines
the energy ratio.
i
