7-7. Current Limit Control *Heat pump model
only
The microcontroller detects the input current so as to
prevent it exceeds a specified value by means of
controlling the outdoor fan control as described in (1)
and (2).
(1) Current limit control (Cooling operation)
Control is performed as shown below by detecting
the compressor operating current with a current
sensor (C.T).
