[C-09]
Alarm output
Indicates the logic of the alarm output on
the digital I/O PCB during
malfunctioning.
▪ 0 (Normally open)(default): The alarm
output will be powered when an alarm
occurs. By setting this value, a
distinction
is
made
between
malfunctioning and detection of a
power failure of the unit.
▪ 1 (Normally closed): The alarm output
will NOT be powered when an alarm
occurs. This installer setting allows for
a distinction between the detection of
an alarm, and the detection of a power
failure.
Also see the table below (Alarm output
logic).
[A.2.2.6.4]
[F-04]
Bottom plate heater
Only applicable for 16.
Indicates if an optional bottom plate
heater is installed on the outdoor unit.
The power of the bottom plate heater is
in this case supplied by the indoor unit.
▪ 0 (No)(default): NOT installed.
▪ 1 (Yes): Installed.
Remark:
If this
value is set, the output on the digital I/
O PCB cannot be used for space
heating output. See
"5 Application
guidelines" on page 12

Energy metering
When energy metering is performed by the use of external power
meters, configure the settings as described below. Select the pulse
frequency output of each power meter in accordance with the power
meter specifications. It is possible to connect (up to 2) power meters
with different pulse frequencies. When only 1 or no power meter is
used, select No to indicate the corresponding pulse input is NOT
used.

Quick wizard: Capacities (energy
metering)
The capacities of all electrical heaters must be set for the energy
metering and/or power consumption control feature to work properly.
When measuring the resistance value of each heater, you can set
the exact heater capacity and this will lead to more accurate energy
data.

Description
[A.2.3.1]
[6-02]
Anti-legionella heater: Only applies to
domestic hot water tanks with an internal
anti-legionella heater (EKHW). The

8.2.5
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 5°C.
See the user reference guide and/or operation manual for more
details about this function.
