# Code Description
[A.2.2.6.3] [C-09] Alarm output
Indicates the logic of the alarm output on the
digital I/O PCB during malfunctioning.
▪ 0 (Normally open): The alarm output will be
powered when an alarm occurs. By setting this
value, a distinction is made between the
detection of an alarm, and the detection of a
power failure.
▪ 1 (Normally closed): The alarm output will
NOT be powered when an alarm occurs.
See also table below (Alarm output logic).

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)
