INSTALLING AND WIRING
Wall Installation:
1. Select location for the Humidifier Control on an inside wall.
Mount the Humidifier Control in a location where low voltage
wires from the furnace area are already in place, or can be
easily run.
2. Drill a 1/2” hole into the wall at the selected Humidifier
Control location.
3. Pull low voltage wires from the furnace area and through the
hole in the wall. Before mounting the Humidifier Control, the
hole in wall should be plugged to prevent drafts affecting the
Humidifier Control reading. All wiring should conform to the
National Electrical Code and local regulations.
4. (See Figure 1) Gently pull knob (A) from Humidifier Control
cover (B). Cover is held in place by snap clips. Remove cover
by pulling carefully. Do not touch the sensing element.
5. Pull low voltage leads through opening in base plate (D).
6. Attach wires to terminal screws on Humidifier Control.
(Note: If wires are “bunched” between Humidifier Control and
wall, base plate may become warped or cracked and
calibration may be affected.)
7. Remove the gasket (not required for wall mount). Attach base
plate with humidistat switch to the wall using two screws (E)
and two wall anchors (F), if necessary.
8. Reassemble Humidifier Control cover by snapping back in
place. Press on knob.
