Hi, This newb could use some help identifying what these valves are for, and if they are something I need to worry about what position they are set to?
Here are some pics showing the ones I'm wondering about...
The valve actuator on the left has half a label beside it that seems to say "suction", but you can't seem to turn it? Is it only done automatically by the system?
The one on the right also has half a label next to it that seems to say "skimmer", and is turnable in both directions, but it's not obvious what it does or which position does what?

There's another valve actuator here next to the heater that has a label that says "pool return", but no indicators what it does if you turn it to a specific direction?

Under this lid similar to the skimmer basket lid a few feet away towards the pool there's some kind of turning valve, what is this for? Turning off the skimmer/watersupply from skimmer? There are two additional valves like this one on the side of the pool and next to the spa (both also under a similar lid cover)

Any help greatly appreciated so that I can start understanding some of the basic equipment around my pool.
