Immersion Style Thermostat Control for Contactor Models
The thermostat will complete control circuit voltage upon a call for heat. Likewise, the control will
interrupt control circuit voltage when the water temperature is sufficient to satisfy the adjustable
temperature limit of control.
High Limit Switch Control for Contactor Models
The high limit switch will interrupt control circuit voltage causing the heater to shut down when the
high temperature limit of the control is reached (196°F±4°F). Once the cause for overheated water
has been determined, the control must be manually reset to restore normal operation.
