Temperature Adjustment
The water heaters covered in this instruction manual are equipped with an electronic control system. The control system senses
temperature from a factory installed immersion temperature probe. The “Operating Set Point” is adjusted to control water temperature. This is an adjustable user setting in the control system’s “Temperatures Menu.” This and all control system menus are accessed through the UIM (User Interface Module located on the front panel of the water heater.
The Operating Set Point is adjustable from 90°F/42°C to 190°F/88°C. The factory setting is 120°F/49°C. See the Control System Operation section of this manual for instructions on how to adjust the Operating Set Point and other user settings.
Set the Operating Set Point at the lowest setting which produces an acceptable hot water supply. This will always give the most energy efficient operation.
