Mode	Green LED	Red LED
No Power to Board	Off	Off
Normal Operation/ Power to Board	Simultaneous Slow Flash
Anti-Short Cycle Lockout	Alternating Slow Flash
Low Pressure Switch Fault	Off	Slow Flash
Low Pressure Switch Lockout	Off	On
High Pressure Switch Fault	Slow Flash	Off
High Pressure Switch Lockout	On	Off

Note: Because the pressure switches are monitored only when "Y1" (Input) is active, the code for pressure switch open will not be seen when "Y1" is off. Instead, the

“Normal Operation" or “Anti-Short Cycle Lockout” code will be seen.

When a pressure switch opens and causes a short cycle lockout, the pressure switch-open code will be seen until it closes, then the short cycle lockout code will flash unless it has already expired.
