NOTE: The holder must be long enough to hold the sensing
bulb in freely circulating air away from the duct wall.
Neatly coil the excess capillary at the controller case

For Outdoor Air Sensing
These models have a 5 ft (1.5 m) capillary that establishes the
maximum distance between the case and the outdoor
Install the bulb on the outside of the building in the shield
provided (See Fig. 15) where it can be exposed to
representative air temperature, but not to direct sunlight. Mount
the bulb high enough so that accumulated snow, leaves, or
other debris cannot obstruct circulation of air around it, and
where children cannot reach it. Avoid vents from the building.
Install the case at the indoor location selected, fastening the
screws through holes in the back of the case. Bring out the
bulb and tubing through a 3/4 in. (19 mm) hole in the outside
wall, avoiding sharp bends or kinks. Leave excess tubing
coiled near the case. Do not make sharp bends near the case
Slip the bulb through the supports in the shield. Pinch the split
supporting clip until it holds the bulb firmly in position. If the
seal-off tube protrudes from under the shield, bend it under as
shown in Fig. 15.
Hold the shield over the mounting position and form a small-
radius bend in the tubing. Place the split plug around the tubing
and move the shield into the mounting location as a unit. Push
the split plug into the hole until it is wedged securely in place.
Fasten the shield in place on the wall with the screws provided.
NOTE: If the tubing is properly shaped and the split plug
