Unit for air to water heat pump system and options
4PW53150-1
[A] Quiet mode
This field setting allows to select the desired quiet mode. Two quiet
modes are available: quiet mode A and quiet mode B.
In quiet mode A, priority is given to the unit operating quietly under all
circumstances. Fan and compressor speed (and thus performance)
will be limited to a certain percentage of the speed at normal
operation. In certain cases, this might result in reduced performance.
In quiet mode B, quiet operation might be overridden when higher
performance is required. In certain cases, this might result in less
quiet operation of the unit to meet the requested performance.
■
[A-00] Quiet mode type: defines whether quiet mode A (0) or
quiet mode B (2) is selected.
■
[A-01] Parameter 01: do not change this setting. Leave it set
to its default value.
[C] Alarm output logic of EKRP1HB
■
[C-01] Defines the logic of the alarm output on the EKRP1HB
remote alarm input/output PCB.
If [C-01]=0, the alarm output will be powered when an alarm
occurs (default).
If [C-01]=1, the alarm output will not be powered when an alarm
occurs. This field setting allows for distinction between detection
of an alarm and detection of a power failure to the unit.
[D] Benefit kWh rate power supply
■
[D-00] Defines which heaters are switched off when the benefit
kWh rate signal of the electricity company is received.
If [D-01]=1 or 2 and the benefit kWh rate signal of the electricity
company is received, following devices will be switched off:
■
[D-01] Defines whether or not the outdoor unit is connected to a
benefit kWh rate power supply.
If [D-01]=0, the unit is connected to a normal power supply
(default value).
If [D-01]=1 or 2, the unit is connected to a benefit kWh rate
power supply. In this case the wiring requires specific installation
like explained in chapter "Connection to a benefit kWh rate
power supply" of the installation manual.
When parameter [D-01]=1 at the moment that the benefit kWh
rate signal is sent by the electricity company, that contact will
open and the unit will go in forced off mode
(1)
.
When parameter [D-01]=2 at the moment that the benefit kWh
rate signal is sent by the electricity company, that contact will
close and the unit will go in forced off mode
(2)
.
[E] Unit information readout
■
[E-00] Readout of the software version (example: 23)
■
[E-01] Readout of the EEPROM version (example: 23)
■
[E-02] Readout of the unit model identification (example: 11)
■
[E-03] Readout of the liquid refrigerant temperature
■
[E-04] Readout of the inlet water temperature
Do not set other values than the ones mentioned.

NOTE [D-00] settings 1, 2 and 3 are only meaningful if
the benefit kWh rate power supply is of the type
that power supply is not interrupted,
(1) When the signal is released again, the voltage free contact will close and
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to "[3] Auto restart" on page 12.
(2) When the signal is released again, the voltage free contact will open and
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to "[3] Auto restart" on page 12.
NOTE
[E-03] and [E-04] readouts are not permanently
refreshed. Temperature readouts are updated
after looping through the field setting first codes
again only.
