(11)A and B: Mount any wall humidistat (control or high limit) over a standard electrical box at a height similar to a typical thermostat. Any wall humidistat should be in a location representative of the overall space being humidified and not in the path of a blower pack or an air supply grille.

(12)A: Mount any duct control humidistat in a location representative of the overall air humidity, usually the return duct. Do not mount it directly in front of the steam distributor or in a turbulent or mixing zone. Mount it where the air’s humidity and temperature are uniform and representative air is over-humidified or approaching saturation.
