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 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
appropriate insulation is provided.
Use extension cable sheathed PVC cable or cable 0.5 mm
to 1.0 mm
.

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
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".

cable (PVC insulated PVC jacketed and either between ø0.65 and
ø1.2, or between 0.3 mm
(2) Change the setting on the main/sub switch (SW1) on the
