Thank you for your question. With your model# B112900 shower faucet you can only control the water volume with the lever. The faucet is equipped with a rotational limit stop on the cartridge that you use to set how hot the water can get. I have attached instructions on how to adjust the cartridge that comes with your faucet. If you have any other questions please contact our toll free Homeowners/Warranty line at 1-800-345-3358 for further assistance.
