Why does my Conext SW report W92 when I connect AC input?

This was designed to sense a 3-phase source, however it tripped on split-phase power too. This nuisance warning would 
not prevent the CSW from operating properly. The latest firmware version 3.01 should address this anomaly. 
The Conext Combox (865-1058) has the ability to upgrade firmware. If the CSW is still within warranty, we can set 
the customer up with a CnxtCfgTool loaner to upgrade the firmware.
