Sprinkler winterizing question

First time to winterize my sprinkler system. Watched bunch of you tub, still have few questions:

1. My Febco 765 back-flow breaker has two test cocks. The upper one and the lower one. When connecting to air compressor line, which one I should connect with?

2. When blow out water by zone, can I use clock panel or I have to use underground manual switches?
