[3] When operating on Extra Low fan speed via external input (The LGH-150 and 200 types cannot be
used)
Usually, ventilation is performed at High (Extra High)/Low fan speed, and there is automatic switching to
Extra Low fan speed when an absence of dirty indoor air is detected by a CO
2
sensor, etc.
Insert the remote display adaptor (PAC-SA88HA-E) into the connector (CN16) on the Lossnay circuit
board, and input the signal (uncharged a-contact) from a CO
2
sensor to the brown and yellow lines.
When the contacts in the diagram below are ON (closed), the system will switch to Extra Low fan speed
regardless of the fan speed settings on the remote controller or the system controller.

[1] When operating on High (Extra High) fan speed via external input
Usually, ventilation is performed at Low/Extra Low fan speed, and there is automatic switching to High
(Extra High) fan speed when dirty indoor air is detected by a CO
2
sensor, etc.
Insert the remote display adaptor (PAC-SA88HA-E) into the connector (CN16) on the Lossnay circuit
board, and input the signal (uncharged a-contact) from a CO
2
sensor to the brown and red lines. When
the contacts in the diagram below are ON (closed), the system will switch to High (Extra High) fan speed
regardless of the fan speed settings on the remote controller or the system controller.
[2] When operating on Low fan speed via external input
Usually, ventilation is performed at High (Extra High) fan speed, and there is automatic switching to Low
fan speed when an absence of dirty indoor air is detected by a CO
2
sensor, etc.
Insert the remote display adaptor (PAC-SA88HA-E) into the connector (CN16) on the Lossnay circuit
board, and input the signal (uncharged a-contact) from a CO
2
sensor to the brown and orange lines.
When the contacts in the diagram below are ON (closed), the system will switch to Low fan speed
regardless of the fan speed settings on the remote controller or the system controller.
