7-5. Ventilation Settings
7-5-1. Night purge
During summer, the Night purge function draws cooler outside air into the room to suppress temperature rises at
night. This energy conservation reduces the load when air conditioning starts the next morning.
Click [Ventilation Settings] in the menu bar, and then click [Night purge Setting] to access the Night purge settings
screen.
All LOSSNAY unit groups that support the Night purge function from AE-200 will appear.
Note: During the Night purge operation, LOSSNAY units operate in the Bypass mode.
Note: Night purge setting cannot be made from AE-200 for the LOSSNAY units that are connected to the AE-50/EW-50 in
communication error.
Note: Some models of LOSSNAY units do not support the Night purge function from AE-200. (As of March 2015, only LGH-RVX-E
models support the function.)
For more details about the Night purge function, refer to the Installation Manual, Instruction Book, or technical documents
that are provided with the LOSSNAY unit .
