Issue:
Oil Flow Control Diagnostic
Resolution:
RTAA 70-125 TON Chillers: This diagnostic will appear if the compressor model number is set up as CHHB. Because of the different way the control looks at oil flow for the CHHB and CHHN compressor it will disregard the oil flow control for the CHHN thinking it has a CHHB compressor. This can be changed in the Service Settings, Machine Configuration menu, under compressor model number prefix.
- RTAA 130-400 TON >>> CHHB compressor
- RTAA 70-125 TON, RTUA 70-125 TON, and RTWA 70-125 TON >>> CHHN compressor
Low oil flow?may have some other valuable information.
In addition...it is advised to check the other settings/setpoints in Machine Configuration and Service Setup Menu's.
