NOTE Take care that [8-03] is always smaller than the
maximum running time [8-01].
By adapting the booster heater delay time versus
the maximum running time, an optional balance
can be found between the energy efficiency and
the heat up time.
However, if the booster heater delay time is set
too high, it might take a long time before the
domestic hot water reaches its set temperature
upon domestic hot water mode request.

[9] Cooling and heating set points
The purpose of this field setting is to prevent the user from selecting
a wrong (i.e., too hot or too cold) leaving water temperature. Thereto
the heating temperature set point range and the cooling temperature
set point range available to the user can be configured.
In case of a floor heating application, it is important to
limit the maximum leaving water temperature at
heating operation according to the specifications of
the floor heating installation.
In case of a floor cooling application, it is important to
limit the minimum leaving water temperature at
cooling operation (field setting of parameter [9-03]) to
16~18°C to prevent condensation on the floor.
[9-00] Heating set point upper limit: maximum leaving water
temperature for heating operation.
[9-01] Heating set point lower limit: minimum leaving water
temperature for heating operation.
[9-02] Cooling set point upper limit: maximum leaving water
temperature for cooling operation.
[9-03] Cooling set point lower limit: minimum leaving water
temperature for cooling operation.
[9-04] Overshoot setting: defines how much the water
temperature may rise above the setpoint before the
compressor stops. This function is only applicable in heating
mode.
[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-00] Compressor
0 Forced off
(default)
1 Forced off
2 Forced off
3 Forced off
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,
[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 "Connection to a benefit kWh rate power
supply" on page 14.
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
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
[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
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.
(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 19.
(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 19.
