[8-04] Additional running time at [4-02]/[F-01]: specifies the
additional running time on the maximum running time at
outdoor temperature [4-02] or [F-01]. See figure below.

[9] Cooling and heating set point ranges
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.
CAUTION
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
60.8~64.4°F (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 set point before the
compressor stops. This function is only applicable in heating
mode.

Solar priority mode
[C-00] Solar priority mode setting: for information concerning
the EKSOLHW solar kit, refer to the installation manual of
that kit.
Alarm output logic
[C-01] Alarm output logic: defines the logic of the alarm
output on the EKRP1HB digital I/O PCB.
[C-01]=0, the alarm output will be powered when an alarm
occurs (default).
[C-01]=1, the alarm output will not be powered when an
alarm occurs. This field setting allows for distinction between

Bivalent operation
Applies only to installations with an auxiliary boiler (alternating
operation, parallel connected). The purpose of this function is to
determine —based on the outdoor temperature— which heating
source can/will provide the space heating, either the Daikin indoor
unit or an auxiliary boiler.
The field setting "bivalent operation" apply only the indoor unit space
heating operation and the permission signal for the auxiliary boiler.
When the "bivalent operation" function is enabled, the indoor unit will
stop automatically in space heating operation when the outdoor
temperature drops below "bivalent ON temperature" and the
permission signal for the auxiliary boiler becomes active.
When the bivalent operation function is disabled, the space heating
by indoor unit is possible at all outdoor temperatures (see operation
ranges) and permission signal for auxiliary boiler is always
disactivated.
[C-02] Bivalent operation status: defines whether bivalent
operation is enabled (1) or disabled (0).
[C-03] Bivalent ON temperature: defines the outdoor
temperature below which the permission signal for the
auxiliary boiler will be active (closed, KCR on EKRP1HB) and
space heating by indoor unit will be stopped.
