When using Mitsubishi Mr. Slim air conditioner with MA Remote
controller
Connect the interlocking cable connector side to CN2L on the circuit
board for the indoor Mr. Slim unit, then connect the lead wire side to
the 1 and 2 of the input terminal block (TM2) for the Lossnay external
controller input. (No polarity)
• Always separate the power supply cable and the Slim-Lossnay
connection cable by 2" (5 cm) or more to prevent the unit from
malfunctioning.
• The Slim-Lossnay connection cable is 9 7/8" (0.25 m) long. When wiring,
extend it as far as necessary.

Within 457 yd (500 m)
Note
• The Lossnay remote controller (PZ-60DR-E, PZ-41SLB-E) cannot be
used with this system.
• Use MA remote controller of Mr. Slim for switching Lossnay ON/OFF
or the fan speed.
• The ventilation mode is "automatic ventilation".
• The Slim-Lossnay connection cable may be extended to a
maximum length of 457 yd (500 m). (Extension cable specifications
are as detailed below)
Ensure that all connections are secure and that the appropriate
insulation is provided.
Use extension cable sheathed PVC cable or cable AWG 20 (0.5 mm
2
to AWG 17 (1.0 mm ).
When the external device has a charged operating signal of 12
VDC or 24 VDC
• Connect the operating signal (wire) from the external device via the
remote output to 1 and 2 on the external control input terminal
block (TM2). (No polarity)

(Follow the operation manual for the external equipment.)
When the external device has an uncharged a-contact signal
• Connect the operating signal (wire) from the external device via the
remote output to 1 and 3 on the external control input terminal
block (TM2).

When interlocking with a pulse output device
(1) Move the pulse input switch [SW2-2] to the ON position.
(Refer to function settings
(2) Connect the pulse output device (i.e., building management system)
to the external control input terminal block [TM2].
• A pulse width of at least 200 msec will be needed.
• When using PZ-60DR-E, it can be set also from the remote controller.
Connecting methods vary depending on the types of pulse signal

When operating multiple Lossnay units
(1) Connect from Lossnay Unit 1 to Lossnay Unit 2, and from Unit 2 to
Unit 3 and so on up to a maximum of 15 units (7 units for F1200)
using a transmission cable (PVC insulated PVC jacketed and either
between AWG 22 (ø 0.65) and AWG 16 (ø1.2), or between AWG 22 (0.3

• For other types of wire, up to two can be connected.
• The operation signal and pulse signal can be connected to the
