F.SOFTWARE FLOW CHART WITH DEFINITIONS

(1)The flow chart in Figure 7 depicts the software logic and definitions.

G.SELF-HELP

(1)The microcomputer applies corrective actions whenever its self-diagnostics identifies a problem that it is able to correct by itself. If the corrective action is not successful then it displays a system message. If the corrective action requires a service person, then the microcomputer’s only resort is to stop the unit and display a system message. The unit never stops unless it has to.

(2)After three days of no call from either the on/off controls or the modulating controls, when active, the three-day drain active feature is automatically activated long enough to drain all water from the steam cylinder. This NORTEC feature will prolong the life of the cylinder. (User selectable, default is ON.)
