PRECAUTIONS
The installer should be a qualified Technician. Disconnect electrical power
before beginning installation. Do not install the humidistat on the warm air
duct. The foam gasket is used for mounting on a return duct only. Conduct
a thorough checkout before leaving the installation.
WALL MOUNTING INSTRUCTIONS
1. Chose a location for the MHX3 about five feet above the floor on an inside
wall with average room temperature and humidity conditions.
2. Drill a small hole in the wall and run low voltage wiring to the location
chosen. Pull about 6” of wire through the hole. Plug the opening to prevent
drafts from affecting the humidistat operation.
3. Remove the housing from the base by prying with a small screwdriver at
the notch in the side of the housing.
4. Mount the base horizontally over the wires using level. Attach directly to
the wall, using four screws provided.
5. Connect wires to screw terminals on the control assembly as shown.
Replace housing.
