No,,,only slotted screw that turns left and right and very touchy. We'll try a little longer to see if I can fine tune and if not,,,we'll put another in. Thank you for the in formation.
I think I have the same style thermostat in my V-63. Just one slotted screw and i don't see any markings on it. I have it about halfway and the soda on the top gets between 32-34 degrees when I put a thermometer in it, after opening.
I have just been doing trial and error. Let me know if you come up with anything.
