Note: This product does not come with a well.

Immersion type controllers for hydronic heating systems that turn off the burner whenever the boiler water temperature rises to the setpoint. Vertical mounting.

Features

• High Limit Aquastat Controller has adjustable set point.
• Models available for use with immersion wells or for direct immersion if faster response is needed.
• A factory-set stop is available on L4080 to prevent setting the control at too high a temperature.
• Models available with second limit switch to shut off all gas to the burner.
• Liquid fill in sensing element expands as the boiler temperature rises.
• At the set point temperature, a diaphragm-actuated snap switch breaks the power supply to the burner primary control.
