Description
1) When temperature of the indoor
heat exchanger drops below 5°C,
the compressor speed is
reduced. (P zone)
2) When temperature of the indoor
heat exchanger rises in the
range from 6°C to under 7°C, the
compressor speed is kept.
(Q zone)
3) When temperature of the indoor
heat exchanger rises to 7°C or
higher, the capacity control
operation returns to the usual
control in cooling operation.
(R zone)
• The louver position can
be arbitrarily set up by
pressing [FIX] button.
• Swing
When pressing
[SWING] button during
operation, the louver
starts swinging.
