8.2.4 External Bypass control (CN26)
The ventilation mode of Lossnay is changed to Bypass mode by input from external switch, etc. When SW1 is "ON" , the
ventilation mode of Lossnay is changed to the Bypass mode regardless of the setting on the remote controller.
<Operation>
When external ventilation mode control is activated, the icon
change ventilation mode from PZ-61DR-E. When using other remote controllers it is also not possible to change ventilation
mode (Once changed, but return automatically). In other word, the external ventilation mode control has higher priority.
Note;
(Display of the remote controller does not change.)
