the controller doesn't monitor the auxiliary contacts, they just electrically interlock the 2 contactors and the other one on Y starts the BB timer. It is best not to use the timer in the circuit at all, I remove it completely and keep it, wire the up to speed contact to the BB terminal and clip the other timer wires flush. This way the BB relay becomes an up to speed relay to pick the valve coils when the motor is actually up to speed, not whenever the timer expires. Use 4 for control power not 2 so the fault contactor drops when safe is open. Take Run from AA, I use an MTA punch down tool to wire right to AA on the MTA plug.
