1. overview
Interaction with the water heater controller is done through an up, a down, and three operation buttons. These buttons are illustrated to the
right. Operation of the three lower buttons is defined immediately above them on the screen. The [UP] and [DN] buttons are used to navigate
through the menus and make adjustments to the water heater.
While the water heater is operating, the user interface will display the desktop screen (if there are no active fault or alert conditions).
An example of this screen is shown to the right. The temperature on this screen is the Operating Set Point. The Operating Set Point is
the temperature at which the water heater will maintain the water inside the tank. The second line on the screen is a text description
of the Operational State of the water heater (please see Operating States for more details).
The following status icons describe graphically operational details of the heater. The legend of all the status icons is listed below.
