C7021J, C7023J, C7031J, C7041J Averaging Electronic
Sensor.
1. Install two supports inside the duct to hold the averaging
element.
2. Cut a 7/8 in. (22 mm) hole in the side of the duct to insert
the averaging element.
3. Fasten the terminal box to the outside of the duct and
thread the element through the hole and into the duct.
4. Use plastic wire ties to fasten the element to supports.
Seal the hole around the element with a rubber
grommet.
5. Secure the end of the element to the duct on the
support to prevent continuous flexing or abrasion.
IMPORTANT
To assure that the C7021J, C7023J, C7031J, C7041J
senses average duct temperature, position the
temperature elements approximately as shown in Fig.
11. Do not allow the elements to touch or be close to
the duct sides.
NOTE: When the sensor is used as a deck sensor in a
multizone system, be sure to space the elements
equally in the duct midstream as shown in Fig. 12.
Install one C7021J, C7023J, C7031J, C7041J just upstream
from the cold deck zone dampers and the other C7021J,
C7023J, C7031J, C7041J upstream from the hot deck zone
dampers. Position the thermistors to sense the average deck
temperature.

C7021J, C7023J, C7031J, C7041J in a multizone system.
C7021R, C7023R, C7041R MOUNTING
1. Install two supports inside the duct to hold the
averaging element.
2. Cut a 7/8 in. (22 mm) hole in the side of the duct.
3. Insert the averaging element into the duct through the
hole.
4. Fasten the terminal box to the outside of the duct and
thread the element through the hole and into the duct.
5. Use plastic wire ties to fasten the element to the
supports. Seal the hole around the element with a rubber
grommet.
6. Secure the end of the element to the duct on the
support to prevent continuous flexing or abrasion.

IMPORTANT
To ensure that the C7021R, C7023R, C7041R senses
average duct temperature, position the temperature
elements approximately as shown in Fig. 13. Do not
allow the elements to touch or be close to the duct
sides.
NOTE: When the sensor is used as a deck sensor in a
multizone system, be sure to space the elements
equally in the duct midstream as shown in Fig. 14.
Install one C7021R, C7023R, C7041R just upstream from the
cold deck zone dampers and the other C7021R, C7023R,
C7041R upstream from the hot deck zone dampers. Position
the thermistors to sense the average deck temperature.
