Compressor Operation, Checkout and Status / Error Codes
OPERATION:
The compressor is a 380VAC three-phase variable-capacity scroll compressor that is approved for use with HFC410A
refrigerant. The compressor, when connected to an inverter, is capable of operating in a running frequency range from 22
hertz up to a maximum of 70 Hertz (maximum hertz is dependent on compressor size). The compressor speed is determined
by demand from the room thermostat.
CHECKOUT:
Figure 40. Compressor Operation, Checkout and Status/Error Codes

the access panel is not possible.
STATUS CODES:
When the compressor is running, the 7segment display on the outdoor control displays (strings) the room thermostat
demand to the compressor as a percentage. (Example:

– compressor is running at 50% of maximum speed.)
