2 When using M-NET for a group of multiple units
●
Even if the units are in the same group, you can only change operation to High/Low for Lossnay units connected to the
sensor.
5.10 When switching By-pass externally
Establish the wire connection by inserting the optional remote display adaptor (PAC-SA88HA-E) in the connector CN16 (Ventila-
tion mode selector).
SW1: When this is ON, Lossnay cannot turn ON/OFF by the
Remote Controller (PZ-60DR-E, PZ-52SF-E).
SW2: When SW1 is ON, Lossnay can be turned ON by set-
ting SW2 at ON or turned OFF by setting SW2 at
OFF.

1 When using PZ-60DR-E or PZ-41SLB-E to connect multiple Lossnay units
●
Connect the sensor to the Lossnay set to “Main”.
●
It is not necessary to connect to any Lossnay with the “Sub” setting.
●
Connect any sensor, etc., with the external change input to the Lossnay unit set to “Main”.
●
Any Lossnay with the “Sub” setting will operate at the same High/Low setting as the Lossnay with the “Main” setting
when there is sensor signal input.

Note:
●
When using the M-NET system, the fan speed being input by the sensor signal will not be displayed on the remote controller.
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 the outdoor air temperature drops lower than 8°C, it
changes to the heat exchanger ventilation. (Display of the
remote controller does not change.)
