Thermostats and external sensors
# Code
[A.2.2.4] [C­05] External room thermostat for the main
zone:
▪ 1 (Thermo ON/OFF): When the used
external
heat pump convector can only send a
thermo
separation between heating or cooling
demand.
▪ 2 (H/C request): When the used
external room thermostat can send a
separate heating/cooling thermo ON/
OFF condition.
[A.2.2.5] [C­06] External room thermostat for the
additional zone:
▪ 0: N/A
▪ 1 (Thermo ON/OFF): When the used
external
heat pump convector can only send a
thermo
separation between heating or cooling
demand.
▪ 2 (H/C request): When the used
external room thermostat can send a
separate heating/cooling thermo ON/
OFF condition.
[A.2.2.B] [C­08] External sensor:
▪ 0 (No): NOT installed.
▪ 1 (Outdoor sensor): Connected to
PCB
temperature.
▪ 2 (Room sensor): Connected to PCB
measuring the indoor temperature.

[A.2.2.6.2] [D­07] Solar pump station kit:
▪ 0 (No): NOT installed
▪ 1 (Yes): Installed
[A.2.2.6.3] [C­09] Alarm output on optional EKRP1HB
PCB:
▪ 0 (Normally open): The alarm output
will be powered when an alarm
occurs.
▪ 1 (Normally closed): The alarm
output will NOT be powered when an
alarm occurs. This installer setting
allows distinction between detection
of an alarm and detection of a power
failure to the unit.

logic).

▪ 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
[A.6.7] [7­04] 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 human­made 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 [7­03] Compares the primary energy use of the
heat pump with that of the boiler.
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.
