such a case, it is required to abort the special operation before normal
Cool/Heat selection setting is used in case the optional
Cool/Heat selector (KRC19-26A) is used. Depending on the
outdoor unit setup (single outdoor unit setup or multi outdoor

details on how to use the Cool/Heat selector option can be
found in the manual of the Cool/Heat selector.

To stop the additional refrigerant charge operation (when
the required additional refrigerant amount is charged), push
BS3. If this function was not aborted by pushing BS3, the
unit will stop its operation after 30 minutes. If 30 minutes

In order to achieve a free pathway to recovering refrigerant
out of the system or to remove residual substances or to
vacuum the system it is necessary to apply a setting which
will open required valves in the refrigerant circuit so the
recovering of refrigerant or vacuuming process can be done
properly.
Default value=0.
To stop the refrigerant recovery/vacuuming mode, push
BS3. If BS3 is not pushed, the system will remain in refriger-
ant recovery/vacuuming mode.
By changing this setting, you can activate the automatic low
operation. Depending on the chosen level, the noise level
will be lowered (3: Level 3<2: Level2<1: Level1).
