    Hi Folks,

    I have a couple of home gardens with drip lines, connected to Hunter valves which have Hunter Latching DC solenoids in them.

    The solenoids were being controlled by a Toro DDCWP (http://www.sprinklertalk.com/manuals/toro/ddcwp_manual.pdf), but the screen is dying so I am looking to replace it.

    I purchased an OpenSprinker Bee, but I can’t get it to control my solenoids properly.

    I have done some experimenting and connected up the old DDCWP controller, and found that when it ‘closed’ a valve it did so by telling the solenoid to extend the small rubber plunger at the bottom on the solenoid.. When it opened the value it retracted the plunger.

    I am guessing that this seals and unseals a opening in the valve that allows the water to flow. It works perfectly with the DDCWP.

    I found with the Bee the behavior was reversed. When the Bee powered on it retracted all the plungers, allowing water to flow. When I started a zone it would extend the plunger, sealing the valve.

    The solenoids have two wires – Black and Red. All the Black wires are commoned and the red wire is connected to signal.

    Any thoughts or advice on what I should be looking at next here?

    Kind regards,
    Stuart.

    I don’t have an OSBee or your valves but couldn’t you just reverse the wiring to the valve to reverse the polarity?

    The polarity on OSBee is as follows: valve’s red wire should go to COM, and black wire should go to an individual zone port.

    For the record, seems the polarity on the Opensprinkler latch is the same as Bee – ie valve’s red wire should go to COM, and black wire should go to an individual zone port.

    Yes, that’s correct. Thanks for pointing that out, we will add that to user manual.
