8 Configuration
Digital I/O PCB
Modification of these settings is only needed when the optional digital
I/O PCB is installed. The digital I/O PCB has multiple functionality
which need to be configured. See "5 Application guidelines" on
page 6.
Demand PCB
The demand PCB is used to enable the power consumption control
by digital inputs. See "5 Application guidelines" on page 6.
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.
8.2.4 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.

Ext. backup heat src
Indicates if the space heating is also
performed by means of an other heat
source that the system.
Q
0 (No)(default): NOT installed.
Q
1 (Bivalent): Installed. The auxiliary
boiler (gasboiler, oil burner) will
operate when the outdoor ambient
temperature is low. During the
bivalent operation, the heat pump is
turned OFF. Set this value in case
an auxililary boiler is used. See
"5 Application guidelines"
on
page 6.

Solar kit
Only applicable for EHBH/X. Indicates if
the domestic hot water tank is also
heated by thermal solar panels.
Q
0 (No)(default): NOT installed.
Q
1 (Yes): Installed. The domestic hot
water tank can –besides by the heat
pump- also be heated by thermal
solar panels. Set this value if
thermal solar panels are installed.
See "5 Application guidelines"
on
page 6.

Alarm output
Indicates the logic of the alarm output on
the digital I/O PCB during malfunctioning.
Q
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.
Q
1 (Normally closed): The alarm
output will NOT be powered when
an alarm occurs.

Bottom plate heater
Only applicable for EHBH/X16 and
EHVH/X16. 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.
Q
0 (No)(default): NOT installed.
Q
1 (Yes): Installed. Remark: If this
value is set, the output on the digital
I/O PCB cannot be used for space
heating/cooling output. See
"5 Application guidelines"
on
page 6.
