(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 the outdoor air temperature drops lower than 46 ˚F
(8˚C), it changes to the heat exchanger ventilation. (Display of
the remote controller does not change.)
