I am trying to adjust water temp, but I have to get the handle off first. Pix included.
I removed the hex screw; tried to pull the handle off; didn't work. Do I just need to pull harder or am I supposed to turn it? counter clockwise is the only direction it will go, which turns on the water.
Pix:
1-handle+
2-Delta showing Delta SA below the handle on the 'backplate'
3-Pat. #3674048 – verified Delta's
4-faucet+ says just SA on underside near a set screw; thing to close the drain says PRICE PFISTER.
I found a pic with the same handle 'Delta Faucet T13290' at Amazon; the rest is different from mine.

Your tub/shower valve is definitely a Delta unit. On their older valves with the "Scald Guard" feature that set screw is the only thing that holds the handle on. As suggested in the comments, spraying with penetrating oil and tapping around the edge of the knob will usually break it loose such that you can pull it off. It is not uncommon (or unwise)for plumbers to use a handle puller made exactly for this task to increase the chances of saving the knob/handle:
These are $12 - $20, maybe less for a cheaply made version. Readily available at the plumbing shop, which you should become familiar with for when the knob breaks during removal...
The temp control limit stop should be a plastic widget with teeth on the underside, just behind the knob, which limits the CCW knob travel. You should be able to pull it away and rotate it CW to give the knob more CCW travel toward the hot inlet port.
