  • Summit - Temp Controller Course Adjustment - Which screw?

    Hello - I have a Summit SBC490B that I'm trying to adjust down a little bit colder. With the normal therm adjustment on max I'm only getting to 42 degrees. I would like to try to get it in the 38-39 degree range.

    The unit has what appears to be a Ranco K57 temp controller. It looks like there are two screws on the side of it. One is flush with the thermostat casing and the other one is inset a bit. Are either of these the course adjustment screw so I can get this a little bit colder? If so, clockwise or counter-clockwise?

    I've been searching and searching on the internet for info on this temp controller and can't find anything.

    Thanks in advance!

    radarthis,
    I need to ask air or water/beer temperature?
    Honestly I've seen more members screw up their thermostat than get colder beer.
    So, is this a new unit? How old? What type of modifications made? How long did you check temperature after adjusting thermostat? Did you open door during this period?
