(The layout of each component inside the control panel, as shown in Figure B, may
differ from the layout in actual units. The control panel layout for outdoor

Control panel for outdoor specifications
(standard models only)
The control panel for outdoor specifications has a double cover
structure as shown in the photograph on the right.
When operating the touch panel display, release the stopper on the
left side of the outer cover to open the outer cover.*
In addition, the electrical components are mounted behind the
inner cover (which houses the touch panel display), therefore it
must not be opened by anyone other than a qualified electrician.
*
The control panel for outdoor specifications is fully-enclosed by the
outer cover, which is splash-proof and rated at IP44 protection, however no such protection
is available when the cover is open. Refrain from operating the touch panel etc. in weather
conditions where there is a risk of water entering the unit. When starting/stopping operation,
or when constant adjustment of the target temperature is required, it is recommended to
use "Start/Stop Operation, Target Temperature Adjustment via External Input/Output".
For detailed information on operation and electrical wiring, see "3. External input/output” in
the "Electrical Wiring" area of the "Installation/Commissioning" chapter.
