5 How To Wire Transmission Line
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

(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 bottom of the remote
controller case.
(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
• Only one remote controller can be connected to a group made up of indoor units.
• The MA Touch Remote Controller cannot be used in combination with other MA remote
controllers.
(4) To interlock to a LOSSNAY or OA processing unit, make the following settings using the remote
controller. (For a description of how to set an interlock, see section 11 "Service menu" (5)
"LOSSNAY setting".)
Set the LOSSNAY or OA processing unit address and the address of all the indoor units you want
to interlock.
(5) Total length of remote controller wiring
• The MA Touch Remote Controller can be wired up to 70 m (229 ft).
NOTE: When interlocking the MA remote controller with a LOSSNAY or OA processing unit,
always set the address of all the indoor units in the group and the address of the
LOSSNAY or OA processing unit.
