(1) Latch-up mode shuts down the control after three consecutive lockouts, and requires a
special procedure to reset. This ensures the owner will call in a licensed technician to
troubleshoot and correct burner problems.
(2) The 90320 provides two limit relays. Carlin's patented SMC technology (Safety Monitoring
Circuit) monitors the contacts of both relays. Lockout occurs if a limit relay contact is found
closed when it should be open.
