Mounting
Location Considerations
IMPORTANT:
To avoid damage to the
circuit board and components, do not mount the
unit in a location where high concentrations of
corrosive vapors are present.
The HC-67x3 controller is shipped with one
mounting base for both surface and wallbox
mounting. To mount the HC-67x3, release the cover
from the base as described in Figure 2.

1. Loosen (do not
remove) the cover

2. Swing the cover

Figure 2: Removing the Cover from the Base
Wallbox Mounting: Special Tools Needed
Use a 1/16 in. (1.5 mm) Allen wrench or
T-4000-119 Allen-head adjustment tool for
mounting.
Wallbox Mounting: Location Considerations
Locate the humidity transmitter on an inside wall,
free from drafts, and out of direct sunlight. The
HC-67x3 is shock and vibration resistant; however,
be careful not to drop or mount the unit where it could be
exposed to excessive vibration. The following ambient
operating conditions apply:
•
Temperature: 32 to 122°F (0 to 50°C)
•
Humidity: 0 to 100% Relative Humidity (RH),
non-condensing; 85°F (29°C) maximum dew point
To mount the HC-67x3 to a wallbox:
1. Pull the cable or wiring through the wallbox and
base.
2. Rotate the mounting base, so one of the arrows on
the base points up.
3. Fasten the base to the wallbox with the
No. 6 screws provided. (See Figure 3.)
Note:
These instructions assume a standard
2 x 4 in. (52 x 104 mm) U.S. wallbox is used.

4. Place the bottom edge of the cover against the
bottom lip of the base, and rotate it up onto the
base. (See Figure 4.)
5. Tighten the cover screw.
