    Lnbuilder 3 pump trotation

    Does anybody have a good routine for rotating hot water/chilled water pumps every 7 days?
    There is no supervisory device. Switching will be via display/scheduler.

    I have something that might work for you I did with distech gfx about 8 or 9 years ago for a domestic booster pump station. I can't remember if it had scheduling in it, but it did lead/lag failover control. At least it will get you heading in the right direction. I'll dig it out and send it to you here in awhile.
    Friends don't let friends Lon.

    It was fairly easy. I hope maybe someone else finds this useful.
