I. TOP DIFFERENTIAL AND BOTTOM DIFFERENTIAL
 A temperature differential represents how far the water
temperature can fall before the water heater must call for
heat again. For example, if the setpoint is 120°F and the
differential is 10°F, then after satisfying at 120°F, the water
temperature must fall to 110°F before the water heater will
call for heat.
J. BUZZER
 The buzzer is programmed to sound every 30 seconds
whenever an error has been detected. It is highly
recommended that the user leave this buzzer on. However,
this option allows the user to turn the buzzer off if desired.
 To turn the buzzer on or off, in the edit mode press the or
buttons to
alternate between “On” and “OFF”.
K. DISPLAY
 The display setting provides the ability to select whether the
home shows the setpoint temperature (diSS) or the
measured water temperature (diSt) inside the tank for the
upper and lower sections. If “diSt” is selected, the home
screen will cycle the display to show the top temperature
(designated by a ‘t’ preceding the measurement) for 5
seconds, followed by the bottom temperature (designated by
a ‘b’ preceding the measurement) for 5 seconds.
