*Note 1
*Note 1: The fan will continue to operate even after operation is stopped with the remote controller, etc.
3 Restrictions when switching fan speed
The following restrictions exist when the fan speed is switched.
When switching between High ( Extra High ) and Low fan speed, the fan will be stopped for approximately
5 seconds.
When switching between Extra Low fan speed and the other fan speeds, the fan will be stopped for ap-
proximately 10 seconds.
4 Air supply fan forced stop
Under the following conditions, Lossnay will force stop of the air supply fan. However, when the following
conditions are met while operating at Extra Low fan speed, the air supply fan will stop, and the exhaust fan
will operate at Low fan speed.
( When operating at Extra Low fan speed, the air supply fan and the exhaust fan cannot be stopped sepa-
rately. )
When Mr. Slim is in defrost or stopped due to a fault, in an interlocked system with Mr. Slim that has a
duct connection with Lossnay.
( For cold inrush prevention, or falling dust prevention )
When the indoor unit is in defrost, in an interlocked system with a City Multi indoor unit that has a duct
connection with Lossnay.
( For cold inrush prevention )
When the outside temperature is 14°F (-10°C) or lower, the air supply fan is stopped periodically for ap-
proximately 10 minutes to 55 minutes.
( To prevent freezing of the Lossnay core )
( 4 ) Ventilation mode control
Lossnay ( heat exchange ) ventilation or bypass ( normal ) ventilation is achieved by switching the air duct inside
the Lossnay unit with a damper.
1 Ventilation mode
There are three control modes.
Lossnay ventilation ( heat exchange ventilation ) mode:
Heat exchange ventilation is performed regularly via the Lossnay core.
Bypass ventilation ( normal ventilation ) mode:
Ventilation is performed regularly without going through the Lossnay core.
Automatic ventilation mode:
A temperature sensor built into the unit provides automatic ventilation to a suitable ventilation mode.
In addition, energy saving ventilation is provided by interlocking with a Mr. Slim or City Multi indoor unit.
