USING THE ELECTRONIC CONTROLLER

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 faults or warnings). An example of this screen is shown to the right. The first temperature on this screen is the temperature of the water inside the tank. The second 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 third 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.
