I was watching "Operation--Annihilate!", and I learned that the phaser had three settings: stun, kill, and a third one. This is between stun (Force One) and Kill (Force Three). I guess this one is Heat.
Knowing this:
2150's
2 settings: Stun and Kill
2260's
3 settings: Stun, (Heat), and Kill
2360's
16 settings
Is there a possibility of there being a phase rifle in the S.S. Enterprise NX-01's armory? I hope so.
There might also be multiple things to be adjusted in a TOS phaser - perhaps "force" is just one of them, while "beam width" clearly seems to be one. You might select several settings within "force one", to produce stun or heat or kill effects depending on how you focus or modulate the beam, and a spectrum of settings within "force three", all of them more powerful than their "force one" equivalents.
In any case, the TOS phasers had those fancy thumb-roll controls that would seem to provide a whole continuum of settings, not just a discrete number of them.

As for the Phase Rifle , I'm hoping they have a Projectile weapon instead , something like the TR - 116 from Ds9 , but of course without the level of advanced tech on it.
Of course they would also need a heavy energy weapon for on ship use , you wouldnt want bullets flying around bouncing off bulkheads and such.
you can read up on the TR-116 at Lee's web site about Phasers and other things that shoot ... things.

Kidding. In fact, even the TOS phasers had more than three settings. There was a dial that went up to - memory fails me, maybe Obvychops can dig something up on my site! - 12, or 14, I think. . .

The TOS Phaser Pistols seem to have a few dials on them. I'm Guessing one of the Dials Selects "Stun" "Heat" "Kill" and the other selects what power level you want for each setting.
