Confirm that the pulse input switch (SW2-2) is set to "OFF".
(Factory setting is "OFF".) (Refer to function settings
Connect the interlocking cable connector side to CN2L on the
circuit board for the Mr. Slim indoor 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 109 yd (100 mm) long.
When wiring, extend it as far as necessary.

Note
• The Lossnay remote controller (PZ-61DR-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".
• 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 ) to AWG 17 (1.0 mm

When the external device has a charged operating signal
of 12 VDC or 24 VDC
[SW2-2] setting vary depending on the types of output signal of
external device.
• Move the pulse input switch [SW2-2] to the ON position.
(Refer to function settings
• When interlocking with a pulse output device, a pulse width is
at least 200 m sec. to turn Lossnay ON, and 10 sec. interval is
necessary to next output.
• The wiring should be the following picture.
