Hi, Pat 45!
Thank you for your question. The Delta Monitor 144713 tub and shower unit does have valve cartridge that has a rotational limit stop that can be adjusted for hotter water. You will want to remove the set screw from the handle with a 1/8" allen wrench. Once the handle is removed you will be able to see the rotational limit stop on the front of the cartridge. To adjust the rotational limit stop:
1. Pull out the inner, off-white circle. It maybe quite stiff.
2. When pulled out far enough, the circle will turn. Left (counterclockwise=hotter, right (clockwise)=colder.
3.Release the circle once it's at the desired temperature.
4. Test the temperature, adjust the rotational limit stop as needed.
Please feel free to call, email, or message us on social if you should need further assistance.
Best regards, Rosanna
