Formula Example
COP = (Electricity price / gas price)
(a)
×
boiler efficiency
If:
▪ Electricity price: 20 c€/kWh
▪ Gas price: 6 c€/kWh
▪ Boiler efficiency: 0.9
Then: COP = (20/6)×0.9 = 3
(a)
Make sure to use the same units of measurement for the electricity price and gas price
(example: both c€/kWh).
2 Determine the value of [C‑03] using the graph. For an example, see the table

a [C‑03]=2.5 in case of COP=3 and LWT=35°C
b [C‑03]=10.5 in case of COP=3 and LWT=55°C
NOTICE
Make sure to set the value of [5‑01] at least 1°C higher than the value of [C‑03].
Electricity and gas prices
INFORMATION
To set electricity and gas price values, do NOT use overview settings. Set them in the
menu structure instead ([7.5.1], [7.5.2], [7.5.3], and [7.6]). For more information on
how to set the energy prices, see the operation manual and the user reference
guide.
INFORMATION
Solar panels. If solar panels are used, set the electricity price value very low to
promote the use of the heat pump.
