Overview
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.
