TROUBLESHOOTING
ERROR STATE:
When an Error condition is encountered a code is displayed and the system is
shutdown to prevent damage, the cooling fans and air compressor will remain on. While the
systems have been designed and calibrated to prevent false alarms this will happen occasionally
when certain monitored parameters such as temperature or humidity go out of range sporadically
/ momentarily.
