One xf-150 It's about a-year-old. If you recall I actually spoke with you on the phone two weeks ago discussing buying another Gyre, which one of the new 200 series is the same as the 150 and running both on the alternating gyre on the tidal program to be controlled by the new 200 series. So after speaking with you I purchased the new 200 series XF 250 and I'm having trouble programming both of them on the alternating gyre tidal mode with anti synch.
