This is how I've been doing it. I've made changes to the process over time and you probably will too.
1. Set up the still, connect water lines, get water flowing (check for leaks), close gate valve and close all water lines.
2. Heat boiler at 100% power 5500W until the base of the column (maybe 1' up) starts to get hot. I set alarm for 100F which is an arbitrary figure. The boiler will be above 180F before this happens.
3. Immediately reduce power to 50% (2750W) and turn the water on for the reflux condenser. I move temp probe to the vapor takeoff.
4. I set an alarm for 120F in the vapor takeoff just so I know that vapor reached the top and reflux has begun.
5. I equalize the column at full reflux for maybe 10 min or so. Keep an eye on the temp and you will see the temp equalize before your eyes.
6. Once you're ready to start taking off foreshots, open water for your shotgun condenser, crack your gate valve open just a little bit (learn YOUR valve). My 1" gate valve is 3 full turns 0.58 lph, approx 3 drips or so per second. I'm sure I could probably take off faster, but I'm not in a hurry. You'll see the vapor temp start to rise as you take off, perfectly normal.
7. After a few jars are full and the Acetone smell appears to be gone I crack the gate valve open a just a little bit more 3-1/2 to 4 turns. Continue taking off until you think you're out of heads and definitely into hearts. You'll learn this with experience. Watch the vapor temp and you'll likely find that it will remain this temp all the way until the end.
8. Once I know I'm into hearts that's when I can let her rip. I open the gate valve 6 full turns (3.2 lph). You will likely have to feed a bit more water to your shotgun condenser because you'll be knocking down much more hot vapor.
9. Watch the vapor takeoff temp, collect in smaller jars near the end and once the temp starts to jump up two or three 1/10th degree you know tails is coming. You can restabalize if you want to compress tails, but more often I do not. I open the gate valve 100% and start raising power incrementally over time until I reach 100% power. You may have to increase flow to your condensers as the water will increase in temp. I keep collecting tails until I feel like stopping. If you want you can keep collecting until your vapor temp is 210F and know you removed 100% of all available ethanol.
10. Cover jars and let them air out overnight. Make your cuts. Toss heads and tails in a Feints container for a future all Feints run. Can keep Foreshots for fire starter, solvent, adhesive remover, etc...
When I state how many turns on my gate valve 3 turns for instance, that's 3 turns from the closed position. When I say 6 turns, that's also 6 turns from the closed position. I just don't want you opening 6 ADDITIONAL turns from the previous position
Occasionally test your output's % ABV to make sure you're reaching azeo. If you aren't getting azeo then there is definitely something wrong. Close your gate valve, shut off power, pour the bad product ideally down through the hole above your reflux condenser. Start again by stabilizing the column.
This is just how I do it. It can be done different ways as bunny pointed out. I do it in a more conventional manor I suppose because that's how most tutorials generally say how to operate a VM.
I cannot give specific advice on how to use SPP to its max potential because I use Lava Rock. I look at SPP as just another type of packing. I personally would treat it as such, try to make azeo at least 3.2 lph as described above then try to step your power up from there to get higher production rate as you become more comfortable. You've got some rabbit holes to go down when it comes to operating SPP in a semi-flooded state and other similar SPP topics.
