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.
