Thank you for your question. There is a rotational limit stop that can be adjusted so that the faucets more hot water to come out. To adjust, please remove the temperature cover and take a phillips head screw driver and turn the set screw counter clockwise to remove.
Please remove the gray knob. Behind the knob, you should see a black disk. Please take this disk and take it out and place the disk to the hotter side. The hot side should be up against the iron piece that is sticking down on the volume handle. If you need some assistance, please call us at 1-800-345-3358 for further instructions. I hope this helps.
