I am trying to replace a Bryant 34427dp120 thermostat with an Edge Pro 33cs thermostat. The Bryant thermostat has wires labeled - going clockwise at top - G, Y, W1, E, W2, F, O, R, T. The Edge Pro has Rc, Rh, W/W1, G, Y/Y2, C, O/W2/B, Y1.
I can correspond Y, W1, O, R but am at a loss how to connect E, F, W2 (separate from O), and T. T might be the same as C.
