temperatures
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°. 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 water temperature drops below 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
the 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.
