The wiring is different when the remote controller is connected to a CITY MULTI control system (“-A”
type and later) and when it is connected to a Mr. SLIM air conditioner (A control type). The wiring also
differs with the system configuration. Check the system used.
1. Connecting to CITY MULTI control system
The numbers (1) to (4) in the figure correspond to items (1) to (4) in the following description.
(1) Wiring from the remote controller
• Connect to the MA remote controller terminal block (TB15) on the indoor unit.
• The terminal block has no polarity. Connect to the terminal block at the rear bottom of the remote
controller.
(2) Operating in a group (Groups 03, and 04 above)
• Interconnect the MA remote controller terminal block (TB15) of the indoor units you want to
operate as a group, and connect the MA remote controller to that point.
• When the remote controller is used in combination with the system controller as shown in the
figure above, group setting at the system controller (central controller in the figure above) is
necessary.
(3) Number of connectable remote controllers (groups 02 and 04)
• A main remote controller and one sub remote controller, a total of two, can be connected to a
group made up of indoor units.
NOTE: When using this Simple MA remote controller in combination with other MA remote
controllers, be sure to follow the compatibility rules below.
