Operating Set Point And Differential Adjustment

The Operating Set Point is adjustable from 90°F (42°C) to 180°F (82°C) for commercial and 160°F (71°C) on residential models. The factory setting is 120°F (49°C). The Differential is adjustable from 2° to 20°. The factory setting is 8°. These user settings are accessed from the Temperatures menu. These instructions explain how to adjust these settings and navigate the control system.

When the water temperature sensed by the control system from the Temperature Probe reaches the Operating Set Point the control system will end the heating cycle. A heating cycle will be activated again when the sensed water temperature drops below the Operating Set Point minus the Differential setting.

Note: Set the Operating Set Point to the lowest setting which produces an acceptable hot water supply for most efficient use. Lower Differential settings may cause excessive heating cycles (short-cycling) which can cause premature failure of components such as the Igniter. Set the Differential at the highest setting which produces an acceptable hot water supply to prevent short cycling.
