Welcome to Just Answer. I will do my best to fully answer your question(s).
I am very familiar with Kohler but unfortunately NOT this particular valve. this link is the only thing I could find to assist ME! Not much help to guide you from myself but you can aparently post to this link and they will help you. Good luck, sorry i could not be more specific for you tonite. I tried, no need to pay me unless you want to.
I am very familiar with that link. Kohler phone support is helpful, but only work 8-5. THanks for trying.
Here is a pdf file on page 11 and 12 you will see how to adjust this valve to the temp you want.
I hope this will help you.
