Sounds like the temperature needs to be adjusted or you want to set the personal temperature the way you like it. For a temp adjustment you need a plumber. Go to the website > Technical > Installation Instructions > Scroll down to Shower Valves > determine the valve StyleTherm TH51-R 1/2" Thermostatic Valve with Single Volume Control Rough Installation Instructions.

You will note that there is a Warning: This valve is factory set to deliver water at 100 degrees F., however, it is the installer's responsibility to verify correct temperature setting to prevent risk on scalding or other severe injury prior to consumer use. The installer is responsible for adjusting maximum temperature setting according to Thermostatic Rough and Thermostatic Trim Installation Instructions.

To set a personal temp you may have to call the manufacturer as some valves are different. I couldn't find instructions on their site for you. Give them a call.
