energy costs. Set to Ecological, the heat source will be selected
based on ecological parameters, resulting in a minimisation of
primary energy consumption.
# Code
[A.6.7] [7‑04] Defines whether switching between
operation modes is either economically
or ecologically optimised.
▪ 0 (Economical)(default): reduction of
energy costs
▪ 1 (Ecological): reduction of primary
energy
necessarily energy costs
Primary energy factor
The primary energy factor indicates how many units of primary
energy (natural gas, crude oil, or other fossil fuels, prior to
undergoing any human-made conversions or transformations) are
needed to obtain 1 unit of a certain (secondary) energy source, such
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, step: 0.1 (default: 2.5)
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.
Space heating control
The basic required settings in order to configure the space heating of
your system are described in this chapter. The weather-dependent
installer settings define the parameters for the weather-dependent
operation of the unit. When weather-dependent operation is active,
the water temperature is determined automatically depending on the
outdoor temperature. Low outdoor temperatures will result in warmer
water and vice versa. During weather-dependent operation, the user
has the possibility to shift up or down the target water temperature
by a maximum of 10°C.
See the user reference guide and/or operation manual for more
details about this function.
