  • Model 4200a (For atmospheric draft boilers, mounted internally)
  • Model 4200i (For induced draft boilers, mounted internally)
  • Model 4200ax (For atmospheric draft boilers, mounted externally)
  • Model 4200ix (For induced draft boilers, mounted externally)

 

Features!

Temperature Limit

      • Designed for atmospheric and/ or induced draft gas boilers

Low Water Cut-Off

      • Provides protection against potentially dangerous low water conditions when installed with the Hydrolevel Electro-Well™

Boiler Reset

      • Thermal Targeting – On-board microprocessor saves fuel by adjusting boiler temperature based on heating demand
      • Outdoor Reset Ready – Provides outdoor reset and warm weather shutdown with addition of Outdoor Sensor Kit
