Single handle bathtub faucet
 

Looking for repair info on:
'horizon comfort zone'

This is actually a bathtub faucet in an older hotel. I cannot find anything on the faucet but 'comfort zone'. the Horizon is the only thing I can find doing a google search.

Need repair info, parts info, where to get parts info.
Here is a pic:

Thanks in advance.
