as electricity. The primary energy factor for natural gas is 1.
Assuming an average electricity production efficiency (including
transportation losses) of 40%, the primary energy factor for
electricity equals 2.5 (=1/0.40). The primary energy factor allows you
to compare 2 different energy sources. In this case, the primary
energy use of the heat pump is compared to the natural gas use of
the gas boiler.
# Code
N/A [7‑03] Compares the primary energy use of the
heat pump with that of the boiler.
Range: 0~6
INFORMATION
▪ The primary energy factor can always be set, but is
only used in case the savings mode is set to
Ecological.
▪ To set electricity price values, do NOT use overview
settings. Set them in the menu structure instead
([7.4.5.1], [7.4.5.2], and [7.4.5.3]). 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.

INFORMATION
In order to optimise comfort as well as running costs, it is
recommended to choose weather-dependent setpoint
operation. Set the settings carefully; they have significant
influence on heat pump as well as boiler operation. Too
high leaving water temperature can result in constant boiler
operation.

Description
Leaving water temperature modulation:
▪ 0 (No): Disabled
▪ 1 (Yes): Enabled. The leaving water
temperature is calculated according
to the difference between desired
and actual room temperature. This
allows better matching
heat pump capacity to
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.
