When in the <b>Pump Startup</b> or <b>Operating</b> state, the flow rate is briefly shown on the LCD in GPM. If the value is not valid, <tt>Fault</tt> is shown in place of a flow rate value. | When in the <b>Pump Startup</b> or <b>Operating</b> state, the flow rate is briefly shown on the LCD in GPM.

The surge tank | The surge tank level is monitored by a differential pressure sensor with built-in signal conditioning that generates a 4-20 mA signal proportional to the water depth. | ||
The value is considered valid if the current measured is greater than or equal to 4 mA (not an open circuit). The low and high thresholds are based upon the required flow turnover rate for the pool volume and a maximum to avoid issues (channeling) in the filter tanks. | The value is considered valid if the current measured is greater than or equal to 4 mA (not an open circuit).
