The Operating Set Point is adjustable from 90°F (42°C) to 160°F (71°C). 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. 

From the Desktop screen, press the Operational Button under 

MENU. The Main Menu screen will be displayed.
