Location and Mounting 

H1008A,D Automatic Humidity Control 

IMPORTANT

Do not install H1008 on supply air. Temperatures 
in excess of 120°F cause the control to go into 
error mode. If mounting near an elbow area, 
keep the control 6 in. (152 mm) upstream from 
the elbow so the humidity and temperature sen- 
sor is exposed to the normal airflow (Fig.1).

Locate the control at least 12 in. (305 mm) upstream from 
the humidifier (or dehumidifier/ventilator supply air) in the 
return air duct where it can be exposed to the air stream 
of the return air. See Fig. 1.

Fig. 1. Select duct location for control.

Use the following procedure to mount the H1008A,D in 
the return air duct:

1.

  Î

emove the cover by placing your thumb in the bot- 

tom notch between the cover and the base and pull-

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. 5-9. Use 
either straight in or wraparound wiring connections. 
See Fig. 4.

pump. 

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:
