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.
