Connect to 6 and 7, or 7 and 8 of the monitor output terminal
block (TM3) with reference to the wire connection diagram.
Note
* Don't tighten screws of terminal block with a torque larger than
0.5Nm. It could damage the PCB.
Bypass or Delay 2 monitor output with delay function 2 can be
possible. (Refer to function settings
When connect to an Electrically operated damper, or take

the optional remote ON/OFF adaptor (PAC-SA88HA-E) in the
connector CN16 (High/Low selector) as shown by the figure.

SW1: High fan speed operation switch
Not used. Insulate completely.
(When closed: For High fan speed operation)
Max wiring length 10 m
When SW1 is "ON", fan speed of the Lossnay will be set to "High"
(Extra-High) regardless of the remote control setting.
Use this in such a way that it ventilates at Low fan speed normally,
and when the external sensor detects contamination of indoor air,
it changes to High (Extra High) fan speed operation.
To force Low fan speed externally
CO
sensor, etc.
Remote ON/OFF adaptor

Not used. Insulate completely.
(When closed: For Low fan speed operation)
Max wiring length 10 m
When SW1 is "ON", fan speed of the Lossnay will be set to "Low"
regardless of the remote control setting.
Use this in such a way that it ventilates at High fan speed
normally, and when the external sensor detect that the indoor air
contamination is low, it changes to Low fan speed operation.

SW1: Bypass ventilation operation switch
(When closed: For Bypass ventilation operation)
Max wiring length 10 m
With SW1 is "ON", the ventilation mode of Lossnay is changed to the
Bypass ventilation regardless of the setting on the remote controller.
* When the outdoor air temperature drops lower than 8˚C, it
changes to the heat exchanger ventilation. (Display of the
remote controller does not change.)

The remote controller (PZ-41SLB-E) cannot be used.
Insert the optional remote ON/OFF adaptor (PAC-SE55RA-E) in
CN32 on the Lossnay control PCB.

* If centralized control is performed according the wire
connection shown in this section, the remote controller (PZ-
41SLB-E) cannot be used.
M-NET transmission cable input terminal block
• One shielded wire is connected to TB5 S on the PCB on terminal.
Address setting is required. (Refer to function setting section.)
M-NET transmission cable: Connect any of the City Multi indoor unit, or
Mitsubishi Electric Air-Conditioner Network
System (MELANS) - to the Lossnay.
• Connecting positions are different for the Remote Controller
PZ-60DR-E and PZ-52SF-E.
PZ-60DR-E:
Connect to TM4 1, 2 on the PCB. (See Section
connecting with Remote Controller (PZ-60DR-E)".)
PZ-52SF-E:
Connect to TB5 A, B on the same terminal block as for the
M-NET transmission wires.
• Securely connect the M-NET transmission wires to TB5 AB.
