Safety temperature limiter (STB) boiler or burner -Easypell-

If there is excess temperature in the boiler (e.g. if the pump fails), the safety temperature limiter is triggered and interrupts the pellet supply. Only after the boiler has cooled down can the STB be unlocked mechanically (manually).

There are two variants to choose from:

• STB for the boiler
  or
  
• STB on the burner

Please select the required variant.
