90320 Temperature Limit Control
Specs At A Glance
Temperature Limit (ºF) 50-240 Varys by appliance
High Limit 160-240 Varys by appliance
Power Input (VAC) 240
- Multiple sensor option (3) (Using individual and/or dual sensor assemblies)
- Sensor Redundancy (Higher temperature of two operating sensors used)
- Easy remote sense (Electronic sensors wired to control)
- 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.)
