Hitachi recommends PC-ARFP(1)E remote control in order to obtain the maximum RCI-(1.0-6.0)
FSR1 performance. For detailed functions should be referred to remote control Installation and
Operation Manual.
7.1 High speed setting function
This function allow to set the air flow volume higher than normal air flow volume steps. It is
for high height ceiling on site. Set the fan speed from control remote function selection menu
depending on a ceiling height as shown in the table below.
Ceiling Height
1.0 to 3.0HP
Below 2.7m
2.7 to 3.0m
3.0 to 3.5m
7.2 Circulation function at heating thermo-off
This function maintains the fan operation by the set air flow volume at the heating Thermo-OFF. It
is for improvement of temperature distribution at high height ceiling site.
7.3 Motion sensor function
Only for panel P-N23NA2 with motion kit PS-MSK2 and PC-ARFP(1)E remote control installation.
The motion sensor detects a human activity by the change of the infrared light. This function saves
the air conditioning capacity (adjusting the set temperature, the air flow volume and the air flow
direction) automatically depending on a situation. The operation after the motion sensor detects
as absence can be selected from "Running", "Stand-by" or "Stop" on the remote control switch
with the capacity saving.
In the case that the indoor units are operated by 2 remote control switches, the motion sensor
setting is available only from the main remote control switch.
NOTE
The indoor unit without the motion sensor and the indoor unit with the motion sensor can be mixed
to install. In this case, when the operation is stopped by the motion sensor control, the indoor unit
without the motion sensor will also stop the operation.
The motion sensor control adjusts automatically the following items depending on a situation.
• Setting Temperature: The temperature is adjusted 1ºC or 2ºC for saving capacity.
• Air Flow Volume: The air flow volume is adjusted to lower one volume or to "Slo" (except during
the dry operation).
• Air Flow Direction: The air flow direction is adjusted to horizontal.
