Gary,
With all the work on your panel something may be plumbed wrong. Choose one valve, say hot kitchen sink. Try it fully clockwise then fully counter clockwise to determine the position for full on. Once you know that set each of them fully on one at a time, all except the manifold drain valves. Go in and test that positions faucet. See if they all match up with the labeling on the panel. You will find out if this piping is correct to the panel labeling. If that is correct all of the hots should work the same. Test each hot and cold faucet a good length of time given the piping distance. See what works per the panel labeling and what does not. There are only so many pipes and positions so they all must be on the manifold to have pressure. You may have the hot and cold manifold feed pipes reversed, for instance. The kitchen might work with that given you do not know which way the single lever is supposed to be set to get hot. By having all of them off and testing them one at a time you will know if the are plumbed right. The other thing to check is that your outside faucet valves are fully off. If those were on but you had say a sprayer as a second valve shut off the water may mix hot and cold and then feed back into the supply manifold. Once you know that the piping is all correct, each valve will be left in the fully on, I think counterclockwise position, or counterclockwise if that is on. Once the piping is right and the valve positions are right this should all work. Hope this helps.
