Thank you for your question. To increase the water temperature for the 144757-SP, you will want to adjust the rotational limit stop. To change 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.
