Testing the flow switch
5. Reconnect the return hose to the pump and turn ON the power. Press and hold the current selection knob (8).
6. Measure the VDC between TP210 and TP206.
TP206 is common on PCB3. TP210 provides a filtered, 67% scaled, voltage from the flow switch. 0.45 VDC
(0.67 VDC at the flow switch) equals 2.3 lpm (0.6 gpm). If the TP210 voltage reading is below 0.45 VDC and
the flow is equal to or above 3.0 lpm (1 gpm), replace the flow switch.
