Outline of specifications
1) The heating operation is performed as follows based on the
detected temperature of Tc sensor or Tcj sensor.
• When [M] zone is detected, the commanded frequency is
decreased from the real operation frequency. 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.

NOTE:
When the operation has started or when Tc or Tcj < 30°C at
start of the operation or after operation start, temperature is
controlled between values in parentheses of A and B.
1) In cooling operation (including Dry operation), the drain
pump is usually operated.

switch keeps operating for approx. 4 minutes, a check code
is output.
When heating operation stops, in some cases, the indoor fan
operates with (L) for approx. 30 seconds.
