STEP 1: Unpack the Humidifier Control Carton
Make sure all components are present (see Figure A):

STEP 3: Check the Jumper Blocks
With the cover removed, notice 5 pins coming up from the base. Make sure the 2 sets of
jumper blocks are correctly set for the type of humidifier being installed (see Figure B).
STEP 4: Determine Location for Humidifier Control and Mount It
Humidifier Control must be mounted in the Return Duct. For proper operation, the
Humidifier Control must be at least 6 inches upstream of any of the following:
.Humidifier
.Humidifier Bypass Ductwork (if applicablej
.Fresh Air Intake Ductvvork (if applicable) (see Figure C)
After location for Control is selected, use the perforated Humidifier Control template (attached to
these instructions) to mark the duct opening and cut it Use 4 sheet metal screws (not provided)
to mount the Control in the duct opening and make sure Control is sealed tightly to duct.
STEP 5: Determine Location for Outdoor Temperature Sensor
The location of the Outdoor Temperature Sensor must meet these three requirements:
1. Must be mounted on North, East or West side of house out of direct sunlight
2. Must be at least 3 feet from all exhaust vents
3. Must be above expected snow line (See figure D)
Incorrect humidity levels will result if these requirements are not met
STEP 6: Locate Existing Access Hole to Outside
A convenient way to get the Sensor wire outside is to make
use of unused wires running to the A/C condensing unit
(if applicable). Other ways are to use existing holes for
Cable TV lines, telephone lines, A/C lines, etc. Read all
equipment instructions beforehand for possible conflicts
and warnings.
