LSB temperatures / chiller fault

John, Bubba

Some LSB temperatures were in alarm and after investigating we found the chiller to be running on one of two circuits only. After resetting several circuit breakers the unit has started up and appears to be running normally again. The chilled water temperature had risen to ~65F and has now fallen back to ~46F. We are not sure what was wrong but one fan controller was off. This would have generated the "high condensor pressure" fault which was recorded.
