Hello, JimH. Thank you for your question! The Rotational Limit Stop can be adjusted to allow more hot water. To do this, pop off the temperature knob cover, remove the Phillips head screw, and pull of the temperature knob. You can then pull the Rotational Limit Stop out of the handle and adjust it to the desired position. Please also refer to page 7 of the Installation Instructions.
Best regards, Jon
