Quiet Mode Operation (S); Controller Operations; Manual Operation - Rotex RKHBH016BB3V3 Betriebsanleitung

Quiet mode operation ( )
s
Quiet mode operation means that the outdoor unit works at reduced
capacity so that the sound produced by the outdoor unit drops. This
implies that the indoor heating (cooling) capacity will also drop.
Beware of this when a certain level of heating (cooling) is required
indoors.
Two quiet modes are available.

4.6. Controller operations

Manual operation

In manual operation, the user manually controls the settings of the
installation. The last setting remains active until the user changes it or
until the schedule timer forces another setting (refer to "Schedule
timer operation" on page 8).
As the controller can be used for a wide variety of installations, it is
possible to select a function which is not available on your
installation. In that case the message

• Temperature range for heating: 25°C to 55°C
The temperature for heating can be set as low as 15°C (see
"5. Field settings" on page 13). However, the temperature for
heating should only be set lower than 25°C during
commissioning of the installation. When set lower than 25°C,
only the backup heater will operate.
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (as set through field setting [4-02], refer to
"5. Field settings" on page 13).
• Temperature range for cooling: 5°C to 22°C
CAUTION
The actual operation range depends on the values set on
field setting [9].
These values shall be determined based on the
application.
INFORMATION
In heating mode ( h ) or cooling mode (
temperature set point can also be weather dependent (icon
a is shown).
This means that the controller calculates the water
temperature set point based on the outdoor temperature.
In this case the controller shows the calculated controller
set point. The bi button or
display the actual "shift value" and subsequently, to set the
correct value. This shift value is the temperature difference
between the temperature set point calculated by the
controller and the real set point. E.g. a positive shift value
means that the real temperature set point will be higher
than the calculated set point.
