Description
[A.2.2.B]
[C-08]
External sensor
When an optional external ambient
sensor is connected, the type of the
sensor must be set. See
"5 Application
guidelines" on page 11
.
▪ 0 (No)(default): NOT installed. The
thermistor in the user interface and in
the outdoor unit are used for
measurement.
▪ 1 (Outdoor sensor): Installed. The
external outdoor sensor will be used to
measure
the
outdoor
ambient
temperature.
Remark:
For some
functionality, the temperature sensor
in the outdoor unit is still used.
▪ 2 (Room sensor): Installed. The
temperature sensor in the user
interface is NOT used anymore.
Remark:
This value has only meaning
in room thermostat control.
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 11

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).

Bottom plate heater
Only applicable for EHVZ16. 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

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.
