To protect the equipment, certain fault conditions trigger a lockout: The control shuts down and will not restart until the fault is
repaired.
The lockout condition depends on a combination of the failsafe level you have programmed as well as the type of fault
detected.
One of the following fault codes displays when a fault is detected:
• ASF – Indicates air sensor failure.
• FIL – Indicates filter needs to be cleaned or replaced.
• HPF – Indicates high refrigerant pressure. When in Heat Mode, “HPF” does not display and does not cause lockout.
• LAC – Indicates low AC voltage.
• LPF – Indicates low refrigerant pressure. “LPF” has a 10-minute shut down delay.
• PLF – Indicates high water temperature in condensing coil.

AILSAFE

EVEL
0
This level provides minimal failsafe protection and is not recommended. Only the “ASF” fault is detected and displayed. The
control shuts down and will not restart until the fault is repaired. When the fault is repaired the control restarts.
F
AILSAFE
L
EVEL
1
This level provides the failsafe actions of level 0, plus all other faults are detected but not displayed. The system shuts down for
2 minutes or until the fault is cleared, whichever is longer. The system restarts when the fault is cleared.
