[4] Space heating off temperature
Space heating off temperature
■
[4-02] Space heating off temperature: outdoor temperature
above which space heating is turned off, to avoid
overheating.
[9] Heating and cooling 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.
■
[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.
[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 outdoor 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 outdoor 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] Setup on EKRP1HB digital I/O PCB
Solar priority mode
■
[C-00] Solar priority mode setting: for information concerning
the EKSOLHW solar kit, refer to the installation manual of
that kit.
[D] Local shift value weather dependent
Local shift value weather dependent
The local shift value weather dependent field setting is only relevant
in case weather dependent set point (see field setting
dependent set point (heating operation only)" on page
selected.
■
[D-03] Local shift value weather dependent: determines the
shift value of the weather dependent set point around
outdoor temperature of 0°C.
[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
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
16~18°C to prevent condensation on the floor.
NOTE
Do not set other values than the ones mentioned.
