Two showers with two different water temperatures
Your Cartridge comes from the factory with a temperature mix set point. You can adjust the set point on the cartridge - the manufacturers directions should show you how to do this - and since you replaced the cartridge yourself - it should be easy for you to do, and you can then check and adjust your other shower as well if you like. 

I will say this - there is no indicator that says 110 Degrees turn to this point here. You will need to do a bit of trial and error ..
