Wall Mounted Control Humidistat:

Wall-mounted humidistats are usually installed 4 ft. to 5 ft. above floor level. Often, the best location is beside a thermostat that controls temperature in the same space that is to be humidified, if that loca- tion meets the following criteria:

•The control humidistat should be located where it will be exposed to the average air condition of the space to be humidified.

•Avoid areas of restricted air circulation, or locations where the sensor will be subjected to air drafts, localized heat, or moisture sources.

•Locations near coffee machines, computer blower outlets, doors to other rooms, or windows that can be opened are not suitable.
