The improved userfriendly diagnostic LEDs simplify installation and troubleshooting, ensuring proper operation and saving time.

Standard Features:

  • For residential and commercial applications
  • 15 second delay on make; 10 second delay on break
  • Green LED multi-function test light
  • Red LED low water indicator light
  • Shorted probe indication
  • No blow-down required when mounted directly to boiler trappings
  • Meets ANSI specification Z21.13a
  • No lockout with loss of power if probe is in water
