output.
The outdoor unit motorized valve is
closed due to the overload control.
Frequency comes to
the minimum level.
(HP is maintained
at a constant level.)
LP rises due to
reduced frequency.
To maintain HP, frequency reduces
under the capacity control.
HP drops or rises immediately
after the overload control is
complete.
LP drops due to closed
