Remote controller cover
4. Wood screw (4.1 × 16, used for directly hooking to the wall) ......................................... 2
5. Caution label (in 10 languages) ..................................................................................... 1
(3) Up to two remote controllers can be connected to one group
• When two remote controllers are connected to one group, always set the master remote controller and subordinate remote controller.
• When only one remote controller is connected to one group, set it as the master controller. When two remote controllers are connected to one
group, set the master remote controller and subordinate remote controller. (For a description of how to set the master/subordinate switch, see
step 6 in section
4 How To Install .)

controller
1.
Choose a place in which to install the remote controller (switch box).
Be sure to observe the following steps:
(1) Temperature sensors are provided with both the remote controller and the indoor units. When using the
30 mm
remote controller temperature sensor, the master remote controller detects the room temperature. Install
the master remote controller in a place where the average room temperature can be detected and which
is not affected by any heat source from direct sunlight or air blown from air conditioning units.
(For how to set the master and subordinate remote controller, see step 6 in section 4 How To Install .
For how to set the temperature sensor, refer to the Free Plan indoor unit installation manual. For Mr. Slim
air conditioners, see section
8 Function Selection of this installation manual.)
(2) When installing on either the switch box or the wall, allow extra space around the remote controller as
120 mm
shown in the figure at the right.
(When using the remote controller in combination with a Program timer, refer to the Program timer instal-
lation manual.)
NOTE: Make sure that there is no wiring or wire near the remote controller sensor. If there is, the remote controller cannot detect the exact room
temperature.
(3) Parts which must be supplied on site.

Remove the remote controller cover.
• Insert a minus screwdriver into one of the open slots and move the screwdriver in the arrow direction.
CAUTION Do not turn the screwdriver in the slot. Doing so may damage the slot.
3 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) 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 symbols "A" and "B" on the terminal block.
(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 also it in combination with a CITY MULTI control system 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 master remote controller and one subordinate remote controller, a total of two, can be connected to a group made up of indoor units.
(4) To interlock to a LOSSNAY, make the following settings using the remote controller. (For a description of how to set an interlock, see section
7 Ventilation Setting .)
Set the LOSSNAY address and the address of all the indoor units you want to interlock.
(5) Total length of remote controller wiring
• The remote controller can be wired up to 200 m. Procure 0.3 to 1.25 mm
3
, 2-core cable at the installation site.
CAUTION Remote controllers cannot be wired together. Only one wire can be connected to the remote controller terminal block.
NOTE: When interlocking the MA remote controller with a LOSSNAY, always set the address of all the indoor units in the group and the address
of the LOSSNAY. If this is not done, the LOSSNAY will not operate.
2.
Connecting to Mr. SLIM air conditioner
The remote controller wiring depends on the system configuration. Check the system configuration. Wire the remote controller as shown in the
example below.
The numbers (1) to (3) in the figure correspond to items (1) to (3) in the following description.

(2) When grouping with difference refrigerant systems
• Group using the remote controller wiring. Connect the remote controller to an arbitrary indoor unit of each refrigerant system you want to group.
• When mixing different types of indoor units in the same group, always make the outdoor unit connecting the indoor unit with the most
functions (wind velocity, vane, louver, etc.) the master unit (refrigerant address = 00). Also, when the master unit is the simultaneous

CAUTION Do not into turn the screwdriver in the slot. Doing so may damage the slot.
NOTE: A protection sheet is stuck to the operation section. Peel off this protection sheet before use.
9.
Affix a caution label.
A caution label in English is supplied on the back surface of the control panel door. Affix another caution label in the language of a country where you
use the remote control over the English one.
5 How To Connect Optional Parts
The exterior design for PAC-SC32PTA (Program timer) is different form the one for PAR-20MAA.
When connecting a Program timer, connect a 5-core cable to the connector on the remote controller. (A 5-core cable is
supplied with the Program timer.)
To route the cable, cut off the thin-wall portion.
For wiring path convenience, install the Program timer to the left-hand side of the remote controller. When expansion is
expected, take into consideration remote controller space at the left-hand side.
For the operation method details, refer to the Program timer installation manual.
