    M.O. Flo (Modulation Output Flow) ® M.O. Flo (Modulated Output Flow) is specifically designed for Pentair branded heaters with an IntelliComm Communication Center, although it can be used for other functions, such as water effects. This feature allows you to have flexibility in flow control if the filter cycle flow is less than needed for certain devices. M.O. Flo also allows you to program intervals of flow separated by a specific duration which can be useful for water effects.

  • Page 32: External Control With Intellicomm

    ® The IntelliFlo VF Variable Flow Pump can be remotely controlled by the Pentair IntelliComm communication center using an optional communications cable (P/N 350122). The communication center provides four pairs of input terminal connections. These inputs are actuated by either 15 - 240 VAC or 15 - 100 VDC. Using the device’s inputs, the pump’s external control Programs 1-4 can be controlled.
