decreased. After then
the commanded frequency changes
every 30 seconds
while operation is performed in [M]
zone.
• In [N] zone, the commanded frequency is held.
• When [L] zone is detected, the commanded frequency is
returned to the original value by approx. 6Hz every
60 seconds.

< 30°C after
operation start,
the release
temperature is controlled b

is output.
When heating operation stops, in some cases, the indoor fan
operates with (L) for approx. 30 seconds.
