I am having trouble using the themostat on my new 4100B. I tried the BR one first. ran though all modes slowly. Only the furnace mode would work . I gave up. I then tried living room. went through all modes. Again only the furnace would come on. Gave up there to. Went to the garage one. Went through the modes, The cooling came on in a couple of seconds! What am I doing wrong with the other two? I tried this several times. Always the same. I did turn off the garage to try the other two again. No change. Thanks for all the help for this newby.
