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).
Fig. 7-7-1
(2) Current limit control (Heating operation)
Control is performed as shown in Fig. 7-7-2
Fig. 7-7-2
Remark :
This function is available only for heat pump model (Cooling models have no a current sensor (C.T.)).
