[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 solar kit
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 "[1] Weather
dependent set point" on page 14) is selected.
■ [d-03] Local shift value weather dependent: determines the
shift value of the weather dependent set point around
outdoor temperature of 0°C.
