    Controlling a Polaris booster pump w/Current Sensing Relay

    I recently upgraded my old Pentair pump with a new IntelliFlow Variable Speed pump. Unlike the old pump, the new one has builtin controls including a timer. Because it no longer operates on an external timer, I need to devise a new way to get power to my Polaris booster pump (previously the booster pump was powered when the main pump was powered). Both motors are currently wired for 240V.

    Reading over the following (old) thread I see that I can use a current sensing relay for this application: how to control IntelliChlor IC40 w/Current Control Relay

    Based on that thread I picked up a Crouzet DIRT220A current sensing relay and plan on wiring it up as follows:

    L1 240VAC
    -----------+----+-------------------+
    | | |
    | | |
    +--+-+--+-+----+----+----+--+-+
    | A1 | 11 | | E1 | E2 | E3 |
    +----+--+-+----+----+----+----+
    | | |
    | +----+ R | DIRT220A
    | | |
    | | | |
    +--+-+--+-+----+----+----+----+
    | 12 | 14 | B2 | B1 | M | A2 |
    +----+--+-+----+----+-+--+--+-+
    | | |
    | L1 | L1 |
    +---------+ +------+ |
    | Booster | | Main | |
    | Pump | | Pump | |
    +---+-----+ +---+--+ |
    | L2 | L2 |
    | | |
    ----------------+-------------+-----+
    L2 240VAC



    I'm wondering if anyone has had experience with this relay and can verify my wiring in case I've made any mistakes?

    Thanks

    Sorry you have not received a reply. I cannot help with your issue. Even on this VERY busy forum, there are sometimes questions that no one has a good answer for. Your's might be one of them.
