4. Installation method (continued)
The following system configuration
can be created. Connect the necessary
parts.
1 When connecting with remote controller (PZ-62DR-E)
2 When interlocked with indoor unit of air conditioner or other
external device including other manufactures
3 When operating multiple Lossnay units
4 Signal output from Lossnay unit
5 When switching fan speed externally (when a sensor or other
device is connected)
6 When switching By-pass externally
7 To change fan speed by 0 - 10 VDC input
8 When using the remote/local switching and the ON/OFF input
(level signal)
9 When connecting to the City Multi or Mitsubishi Electric Air-
Conditioner Network System (MELANS)
0 To start/stop Lossnay stand-alone operation without using the
remote control
a Control via Wi-Fi interface or MELCOBEMS MINI
b When connecting CO sensor PZ-70CSB-E or PZ-70CSW-E

CAUTION
• When connecting external devices (electric heater, damper,
lamp, monitoring unit, etc.) using output signals of the
Lossnay unit, be sure to install safety equipment for the
external devices.
(It could cause fire, damage, etc. without safety equipment.)

When connecting with remote controller (PZ-62DR-E)
* When controlling Lossnay units with MELANS, connect wires
according to 9 .
Securely connect the transmission cable from the remote controller to
1 and 2 of the input terminal block (TM4). (No polarity)
Wire type: two-core sheathed cable
Wire diameter: AWG 22 (0.3 mm
• If there are two remote controllers, connect them in the same way.
• Keep the overall length of the transmission cable between Lossnay
and the remote controller within 219 yd (200 m).
Note
• Do not tighten screws of terminal block with a torque larger
than 1.2 N ・ m. It could damage the circuit board.
• Take care not to connect the power supply cable or M-NET
transmission cable.
• When connecting multiple cables to the terminal, use round
terminal.
• Solid wire (single-stranded wire) cannot be connected.
• PZ-61DR-E is not available.

Confirm that the pulse input switch (SW2-2) is set to "OFF".
(Factory setting is "OFF".) (Refer to function settings
Connect the Slim-Lossnay connection 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 4" (10 cm) long. When
wiring, extend it as far as necessary.

Note
• Use MA remote controller of Mr. Slim for switching Lossnay
ON/OFF or the fan speed.
• The ventilation mode is fixed to "automatic ventilation" from
MA remote controller.
• 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 15 (1.5 mm

• Only one Lossnay and one Mr. Slim unit can be interlocked.
Multiple units interlock is not possible.
• Lossnay can not be connected M-NET in this case.
[SW2-2] setting vary depending on the types of output signal of
external device.
When the external device has a charged operating signal
of 12 VDC or 24 VDC
• If the input is pulse signal, move the pulse input switch [SW2-2]
to the ON position. (Refer to function settings
• When level signal is selected, the signal width has to be more
than 10 seconds for ON and OFF .
• When pulse signal is selected, a pulse width has to be at least
200 m sec. to turn Lossnay ON, and 10 sec. interval is necessary
to next output.
• The wiring should be as shown by the following picture.
