We moved into our several months ago and the master bathroom shower does allow the water to get hot. It is a Moen and the site does not give instructions unless a particular faucet is chosen for directions on how the limit or how much hot water is allowed to flow from the showerhead can be changed. I tried taking off the handle but but the screws are not in a place that I can easily unscrew them to see what is behind the plate. Any suggestions?

1. Remove handle
2. There is a small plastic or brass ring
3. Either adjust it so you get more hot water or toss it ( see "A" )
4. Reinstall handle
