Notes
Usage
Adjusts the amount of circulating
refrigerant by adjusting the operat-
ing frequency based on the oper-
ating pressure data
1) Detects high pressure
2) Regulates frequency and pro-
vides high-pressure protec-
tion
1) Detects low pressure
2) Provides low-pressure pro-
tection
1) Detects high pressure
