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 exter-
nal controller input. (No polarity)
• Always separate the power supply cable and the Slim-Lossnay
connection cable by 5 cm or more to prevent the unit from
malfunctioning.
• The Slim-Lossnay connection cable is 0.25 m long. When wiring,
extend it as far as necessary.

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 500m. (Extension cable specifications
are as detailed below)
Ensure that all connections are secure and that the appro-
priate insulation is provided.
Use extension cable sheathed PVC cable or cable 0.5 mm
to 1.0 mm 2 .
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)

When interlocking with a pulse output device
(1) Move the pulse input switch [SW2-2] to the ON position.
(Refer to function settings 1 "Settings for pulse input".)
(2) Connect the pulse output device (i.e., building management sys-
tem) 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
Refer to Section 2 "When the external device has a charged
operation signal of 12 VDC or 24 VDC" or "When the external
device has an uncharged a-contact 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 using a transmission
cable (PVC insulated PVC jacketed and either between φ 0.65
and φ 1.2, or between 0.3 mm
(2) Change the setting on the main/sub switch (SW1) on the second
and subsequent Lossnay units to "Sub".
