HE240, HE280 HUMIDIFIER AND INSTALLATION KIT
Selecting Location for Humidistat
•
Select a location for the humidistat on the return plenum or on the wall in the living space.
•
Mounting on the return plenum is the easiest installation for the control wiring circuit.
IMPORTANT
The humidistat must be mounted upstream from the humidifier or bypass duct to ensure
it is properly sensing the relative humidity of the living space. Locate the control at least
8 in. (203 mm) upstream from the humidifier in the return air duct. (See Fig. 3.)
Locating Closest 120 V Electrical Outlet
• Select location with access to an outlet. If not available, contact an electrician to
have one installed.
• Make sure that the 20 ft (6.2 m) of thermostat wire is adequate to reach from the
humidifier to the humidistat, and also from the humidifier to the transformer. Please
note that the thermostat wire will need to be cut into the 2 correct lengths. See
"Wiring" on page 14 for more information.
