Cello WP6-10

• Pressure actuated high limit, safety control for steam heating boilers, It breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level
• Contains an SPST Micro switch snap-acting switch
• Sensitive pressure actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
• A screw on top of the case allows setpoint adjustment without removing the cover
• Differential is adjusted by means of a dial located inside the case
• Recommended minimum setpoint is differential setting plus 1-1/2 psi
• Stainless steel diaphragm sensor element
• Makes at setpoint on pressure fall breaks at setpoint plus differential on pressure rise
