EZ-Temp Model 90300
Dual Limit Temperature Control
With Sensor Redundancy
Operation & High Limit
• Multiple sensor option (3) (Using individual and/or dual sensor assemblies)
• Sensor Redundancy (Higher temperature of two operating sensors used)
• Easy remote sense (Manual reset only if operating limit doesn’t open)
• Smart manual reset (Manual reset only if operating limit doesn’t open)
• Serviceman reset protection (Latch-up after three consecutive lockouts) 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.
• Power-independent lockout (Power cycling won’t reset from lcokout or latch-up)
• Diagnostic LED’s (Power, call for heat, and lockout/latchup)
• SMC Technology (Safety Monitoring Circuit) Provides two limit relays. Carlin’s Safety Monitoring Circuit monitors the contacts for both relays. Lockout occures if a limit relay contact is found closed when it should be open.)
