Display, Alarm and Error Messages
When an alarm or error condition is detected, “Ft” appears in the left display and a corresponding code flashes on the right display. Operational limit
parameter alarms will shut down compressor, fan, pump and heaters. Alphabetical codes will also appear on the right display. An audio alarm will also sound.
After taking corrective action, restart unit to clear fault or error.

Code = 02
