EconoPhase Status Status Description
Normal Operation PRE mode is active (pumps may be on or off).
PB Comms Error PRE pump board comms error.
GC Comms Error GC board comms error.
EEV Comms Error EEV board comms error.
Pump Recovery Time Temporary pump failure (will try later).
Pump Cycle Lock-Out Lock-Out too many pump-to-compressor transitions @ cold ambient.
Outdoor Temp Too High Outside Temperature too high for PRE pump operation.
Unit Is Off Unit is OFF (no cooling, heating, etc.).
Transitioning to PRE Mode Transition to PRE, waiting for the compressor to stop.
Pump Failure Permanent pump failure.
Not Configured for Operation The Pump has not been enabled.
Sensor Reading(s) Invalid Liebert Microchannel ambient or iCOM control (supply, remote, or return) error.
Other Waiting for other circuit
Compressor Dehum Op Dehumidification operation has priority over Mixed/Pump at this time.
