Control Overview - State Water Heaters SUF 119300 Service Handbook

CONTROL OVERVIEW

Interaction with the water heater controller is through an UIM Touch Display called the User Interface
Module (UIM). This screen is also referred to as the "desktop" or "desktop menu".
While the water heater is operating, the user interface will display the UIM screen (if there are no active
faults or warnings).
An example of this screen is shown below.
• 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. The
operational state of the water heater is also indicated graphically by status icons.
