* Frequency Hold = Frequency (or RPM) is not
increasing (can decrease).
Tdis = Temperature Discharge.
SC = Subcooling.
SH = Superheating.
PROTECTION CONTROL
Inverter Compressor Protection Control
The tables below display the amperage where the system will operate normally, the amperage where the inverter protection control will cause
the frequency to drop, and the amperage where the inverter protection control will shut the system off. AC input current is measured at the
inverter compressor (after the point where the current passes through the noise filter).
