When switching By-pass externally.
Establish the wire connection by inserting the optional remote
controller adapter (PAC-SA88HA-E) in the connector CN26 (White).
SW1
SW1: By-pass ventilation operation switch
(When closed: For By-pass ventilation operation)
With SW1 is "ON", the ventilation mode of Lossnay is changed to the
By-pass ventilation regardless of the setting on the remote controller.
When multiple Lossnay units are controlled by one input, PZ-62DR-E is
necessary.
The signal has to be input ed into main unit referring to 3.
* When the outdoor air temperature drops lower than 8˚C, it changes
to the heat recovery ventilation. (In this case, ventilation mode icon
on the display of the remote controller does not change from the
previous mode, it might be different from the actual unit operation.)

To change fan speed by 0 - 10 VDC input
Establish the wire connection by inserting the optional remote
controller adapter (PAC-SA88HA-E) in the connector CN26 (White).

To change fan speed by 0 - 10 VDC input, the wiring should be as
shown by the above picture. Refer to function settings
more details.
When multiple Lossnay units are controlled by one input, PZ-62DR-E
is necessary.
The signal has to be inputed into main unit referring to 3.
CAUTION
• Make sure of correct polarity.

When using the remote/local switching and the ON/OFF
input (level signal)
Insert the optional remote ON/OFF adapter (PAC-SE55RA-E) in

CAUTION
• Do not tighten screws on the terminal block with a torque
larger than 0.5 N ・ m. It may damage the circuit board.
• Always use shielded wires only for the M-NET transmission
cables, and finish the shield properly.
• Be sure to cut M-NET power supply during Lossnay wiring,
otherwise it causes malfunction.
