STANDARD VS. WINDOW MODE
The terms “Standard” and “Window” describe two methods for
setting up the Smart-Switch
TM to monitor pressure.
Standard Mode
In Standard Mode, illustrated in Figure 8, the SP1i (or SP2i) set
point actuates when the pressure being monitored goes above the
set value. At this point, the Smart-Switch
TM might turn off
whatever electrical power is being applied to a pump, for
example, which is increasing or maintaining the pressure. The
switch de-actuates, or resets, when the pressure drops below the
preset decreasing set point (SP1d or SP2d). At this time, the
electrical power to the pump would be turned back on.
