The start value p2302 is only used in mode p2251 = 0 (Technology controller as speed main
setpoint).
After enable of technology controller the start value is present as long as the RFG output
reaches this value.
I component stop, only when r2273 and r2294 in same direction.
By p2251 = 1: p2299 = 0 (default), recommendation: p2299 connected to r1150.
