Having trouble figuring out wiring from weathertron baystat 240 (for a trane electric w/ heatpump) to rth6350d
Old configuration
Red - R
Brown-T
Orange-O
Green-G
Yellow-Y
Black-X2
Blue-B
White- w (with a jumper from w to u)

New options are

Think I have most firgured out- not sure where blue goes. And don't have an L or Rc. Jumper?
