I installed a new Delta Windmere BN LAV shower faucet. Now, the hot water temperature has disappeared in the shower - the water barely gets past lukewarm at best.
All the other household faucets continue to work as before (temperature wise).

I understand that all the newer shower faucets now have built in safety features to prevent scalding. Has this particular model gone overboard on reducing the amount of hot water?

I raised the hot water tank temperature about 20º and the shower barely gets to a comfortable shower temperature. Of course, that caused the rest of the household to have dangerously high hot water temperatures. (I have since returned the tank temperature to the normal setting).

I have already purchased a MOEN Banbury 82912RN to replace the Delta.
I am refraining from installing it until I get some more info, but at least the handle rotates 270º compared to the Delta's 90º rotation. I thought that might be a good sign of better hot water control.
