3 Bypass ventilation prohibited
When the conditions described below are applicable, the ventilation mode will be fixed at Lossnay ventilation.
When bypass ventilation has been set from the remote controller or the system controller, damper operation
will be set to Lossnay ventilation, even though bypass ventilation is displayed on the ventilation mode display.
● When the outdoor temperature is 8ºC or lower. (Product condensation prevention)
When bypass ventilation prohibition has been set under this condition, the prohibition will be cancelled
when the outdoor temperature goes from a temperature of less than 10 ºC to one higher than 10ºC.
● When there is an outdoor temperature (Outdoor Air) thermistor fault.
● When, in the automatic ventilation mode, there is an outdoor temperature (Outdoor Air) or indoor tempera-
ture (Return Air) thermistor fault.
● When Lossnay is set to the automatic ventilation mode and interlocked with Mr.Slim or City Multi indoor units
set to the fan operation mode.
4 Damper operation
The damper provides control with a 30 second period. Accordingly, a delay of 30 seconds maximum may be
generated from ventilation mode switching to damper operation.
