Daikin Altherma hybrid heat pump
4P355634-1F – 2020.10
# Code Description
[A.2.2.C] [D‑0A] Optional gas meter:
▪ 0 (
No
)(default): NOT installed
▪ 1: Installed (1 pulse/m³ )
▪ 2: Installed (10 pulse/m³ )
▪ 3: Installed (100 pulse/m³ )
Savings mode
The user can choose whether switching between operation modes is either
economically or ecologically optimised. Set to
Economical , the system will in all
operating conditions select the energy source (gas or electricity) based on energy
prices, resulting in a minimisation of energy costs. Set to
Ecological , the heat
source will be selected based on ecological parameters, resulting in a minimisation
of primary energy consumption.
# Code Description
[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
consumption, but not 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 Description
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/cooling control
The basic required settings in order to configure the space heating/cooling 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
