ELECTRONIC CONTROL SYSTEM
THE DESKTOP SCREEN
The illustration below shows the control system “Desktop Screen.” This is the default screen. If there are no active Fault or Alert conditions and no user input for approximately 10 minutes the control system will return to this screen automatically.
Model Information: Model information and menu titles are shown in the black bar at the top of the Desktop Screen.
Tank Temperature: Current water temperature as sensed from the immersion Temperature Probe.
Operating Set Point: Temperature at which the control system will maintain tank (water) temperature in the Normal Mode. This line of text will read Economy Set Point whenever the control system is operating in the Economy Mode. See Temperatures Menu section beginning on page 52 and Economy Mode Setup Menu section beginning on page 55.
Status: The Operating State of the control system is displayed beneath the Operating Set Point. See Table 2 on page 51.
Service Note: The Desktop Screen displays text and animated icons that convey operational information.
Review the Status Icons explanation in Table 1 on page 50 and Contactor Configurations on page 30. Learning to use this real time visual display of the operating sequence will help to quickly diagnose operational problems.
