      • Handbook of AC lists conditions of 77F and 50% RH or 80F and 50% RH; more important to be consistent year round; no drastic changes
      • Our temp/RH is fairly slow moving, so will have to see if this is adequate for the printing group
      • Depends on tolerances required by actual occupant; changes in temp/RH can change wood-mounted engravings
      • MOVE stat into space to trend before and after they move in - Joe help
