H1008A,D AUTOMATIC HUMIDITY CONTROL
2. Drill 3/4 in. (19 mm) circular opening for the projec-
tion on the back of the base. See Fig. 3. Place the
device on the duct and mark the mounting holes, or
screw in self-tapping screws.
NOTE: Be sure the sheet metal surface is flat after
drilling and cutting holes.
BASE
Fig. 3. Mount control on return air duct.
3. Mount the base on the duct using the four mounting
screws provided. Tighten the screws until fully
seated with no space between the base and the
duct. See Fig. 3.
4. Run a low voltage wire from the humidifier (and
dehumidifier or ventilator for H1008D) and equip-
ment to the control terminals. See Fig. 5-10. Use
either straight in or wraparound wiring connections.
See Fig. 4.
5. Snap the cover onto the base.
Fig. 4. Proper wiring technique.
C7089H Outdoor Temperature Sensor
NOTE: The C7089H Outdoor Temperature Sensor is
recommended when using the control with heat
pump, multi-stage equipment, or multi-zone
applications.
Mount the sensor (purchased separately):
 out of direct sunlight on the North side of the house.
 at least three feet from dryer vents or other vents.
 above the expected snow line where ice and debris
cannot cover it.
Use the following procedure for mounting:
1. Place the sensor in the clamp provided.
2. Insert the screw provided through both of the holes
in the clamp and fasten the sensor in place.

WIRING
CAUTION
Voltage Hazard.
Power supply can cause electrical shock
and injury.
Disconnect power supply before installation or
servicing.
All wiring must comply with applicable local codes,
ordinances and regulations.
IMPORTANT
Use 18- to 22-gauge insulated wire for proper
wiring. Stranded-tinned wire is recommended.
NOTE: Connect the humidistat to the furnace for two
reasons:
• The control can determine the outdoor
temperature.
• The control knows when the furnace blower
is operating, eliminating the need for current
sensing relays.
To wire the Automatic Humidity Control:
IMPORTANT
When installing a steam-powered humidifier, be
sure to cut steam jumper-wire for proper
operation.
1. Connect 24 Vac power to the 24 Vac HOT and COM
terminals on the H1008A,D.
2. Connect the humidifier to the two HUM terminals on
the H1008A,D as shown in Fig. 6 through 10.
3. In furnace systems with two transformers, connect
CG to the cooling system transformer common and
connect CW to the heating transformer common. Be
sure G and W connect to the R terminals of both
transformers. (If only one transformer is used, leave
the jumper on CG and CW.) See Fig. 5.
4. To wire the C7089H Outdoor Temperature Sensor,
wire the sensor to the two OUT terminals on the
H1008A,D.
IMPORTANT
For proper wiring, use 18- to 22 gauge insulated
wire. Stranded-tinned wire with a maximum
(length of 300 ft (91m) is recommended.
