EZ-Temp Mode: 90000A, B & C

Dual Limit Temperature Control

Operating and High Limit

Features & Benefits

  • Multiple Sensor Option (1 or 2) (Using individual and/or dual sensor assemblies)
  • 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 lockout or latch-up)
  • Diagnostic LED’s (Power, Call for Heat, Lockout/latch-up)
  • 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.)
