HIGH LIMIT SWITCH/ DIGITAL THERMOSTAT

The digital thermostat contains the high limit (energy cut out) switch. The high limit switch interrupts burner gas flow should the water temperature reach 203°F (95°C).

In the event of high limit switch operation, the water heater cannot be restarted unless the water temperature is reduced to approximately 120°F (49°C). The manual reset button on the front of the control then needs to be depressed.

Continued manual resetting of high limit control, preceded by higher than usual water temperature is evidence of high limit switch operation.

Contact your dealer or qualified service technician if continued high limit switch operation occurs.
