14. Mounting the SYSTEM CONTROL Interface Unit

Notes
• The Interface unit 1 should be placed in a location where the connecting cable (5-core) from the interface unit 1 can reach an indoor unit.
• The device will not function properly the connecting cable is extended, so the connecting cable (5-core) should no be extended.
• Mount the interface unit 1 securely to a pillar or wall using 2 or more screws 2 .
Attach the connecting cable (5-core) of the interface unit 1 here. Store extra connecting cable (5-core) in the ductwork space
behind the air conditioner.
If there is any slack in the connecting cable (5-core), use a fastener 9 to keep it in place.
■ When Mounting Directly to a Wall
Mount the interface unit 1 case to the
wall using the mounting screws 2 .
When the interface unit 1 is mounted above
an indoor unit, it should be positioned 40 mm
40 mm
[1-9/16in.] or more away from the unit to ensure
[1-9/16in.]
that ceiling grills can be removed.
or more

15. Notes Regarding Use

The following control information should be thoroughly explained and provided to the users of this device. (Please provide these instructions to the
user once the installation is complete.)
This Interface unit 1 operates room air conditioners using the controls of a City-Multi or P series, but there are several limitations imposed as a
result of the functional differences between room air conditioners and packaged air conditioners.
1. When operating the system using a System Controller, MA Remote Controller, or ME Remote Controller these operations will not appear on the
display of the wireless remote controller.
2. When original dehumidification mode is set with the remote controller attached to the room air conditioner, "Dry" is displayed because there is no
mode corresponding to dehumidification on the MA remote controller, ME remote controller, and the system controller.
3. Because the temperature range of the room air conditioners is broader than a System Controller, MA Remote Controller, or ME Remote Controller,
when the room air conditioners is set to lower than 17°C (63ºF) or higher than 30°C (87ºF), the temperature display on the a System Controller, MA
Remote Controller, or ME Remote Controller will show the minimum or maximum temperature that can be set. (For example, even if the room air
conditioner is set to cool a room to 16°C (61ºF), the display on a System Controller, MA Remote controller, or ME Remote Controller may read "17°C
(63ºF)").
4. Timer operations should be set using only the remote controller that came with the room air conditioners or the a System Controller, MA Remote
Controller, or ME Remote Controller. If both are used to set the timer to the same time, the timer will not function properly.
5. When "Manual operation prohibited" (ON/OFF, setting temperature, operation mode) is set with the system controller, the corresponding operation
by the remote controller attached to the room air conditioner is not accepted, but allowed operation is reflected. A beep sounds during operation to
confirm reception.
6. A part of functions including the operation of horizontal air blow direction cannot be used from the ME remote controller, the system controller, and
the MA remote controller.
