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 0.5 Nm.
It could damage the PCB.
Bypass or Delay 2 monitor output with delay function 2 can be possible.

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

SW1
SW1: High fan speed operation switch Not used. Insulate completely.
(When closed: For High fan speed operation)
Max wiring length 32 ft (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 or Extra-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
2
(When CO decreases: Closed) (Optional) PAC-SA88HA-E

SW1
SW1: Low fan speed operation switch Not used. Insulate completely.
(When closed: For Low fan speed operation)
Max wiring length 32 ft (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.

When SW1 is "ON", fan speed of the Lossnay will be set to "Extra-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 detects that the indoor air contamination is
low, it changes to Extra-Low fan speed operation.
* For LGH-F1200RX , fan speed of the Lossnay will be "Low".

SW1: Bypass ventilation operation switch
(When closed: For Bypass ventilation operation) Max wiring length 32 ft (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 46.4˚F (8˚C), it
changes to the heat exchanger ventilation. (Display of the remote
controller does not change.)
