TEMPERATURES MENU
Operating Set Point and Differential Adjustment
The Operating Set Point is adjustable from 90°F (42°C) to 180°F
(82°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. The following
instructions explain how to adjust these settings and navigate the
control system menus.
Temperatures Menu
Description/Action
From the Desktop screen, press MENU. The "Main Menu" screen will be
displayed.
The Main Menu is where all control system menus are listed, see
(page 47) for a complete list and description of control system menus.
Use the Up and Down slidebar to view all control system menus from the
Main Menu.
Press "Temperatures" to access the Temperature menu.
Press "Operating Setpoint" to access the temperature setpoint menu.
Press "CHANGE" to activate the adjustment mode for this menu item.
Note: Higher Temperature settings increase wear and operating
costs. Set the Operating Set Point to the lowest setting which
produces an acceptable hot water supply. This will always
provide the most energy efficient operation and longer life.
Use the "+" and "-" Buttons to change the current setting.
Press "ACCEPT" to save the new setting. Press "BACK" to discard changes
and return to the previously saved setting.
Note: Use this procedure to change the Differential setting and other
adjustable user settings in the control system menus.
When the water temperature, sensed by the control system
from the two (upper and lower) Temperature Probes, reaches
the Operating Set Point, the control system ends the heating
cycle. A heating cycle is activated again when the sensed water
temperature drops below the Operating Set Point minus the
Differential setting.
Note: Lower Differential settings may cause excessive
heating cycles (short-cycling) which can cause
premature failure of heater components. Set the
Differential at the highest setting which produces
an acceptable hot water supply. Set the Operating
Set Point to the lowest setting which produces an
acceptable hot water supply for most efficient use.
