You should be able to adjust the hove-to angle by trimming the main.
when going into hove-to, you should fully release the main (what you do with the traveller then does not matter...). When the boat has hove-to, if you slightly trim the main, the boat should turn closer to the wind. If you trim the main too much, the main will cause the boat to tack.
