Alarms associated with sensors on economizer control have the ability to be masked so that they do not cause active alarms when sensors were never installed. The open terminals on the economizer control have traditionally been known to cause false sensor faults. A previous version attempted to somewhat decrease these faults, but was known to not be able to fully correct the issue.

All faults associated with the sensors located on the economizer can now be Disabled or Enabled. By default, the faults are enabled. Only the fault indications are masked, any required changes to system operation due to a failed sensor are not impacted by this change.
