C7041R Mounting
Fig. 4. C7031R dimensions in in. (mm).
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.

installing C7041R Averaging Electronic Sensor.
IMPORTANT
To ensure that the C7041R senses average duct
temperature, position the temperature elements
approximately as shown in Fig. 5. 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. 6.
Install one C7041R just upstream from the cold deck zone
dampers and the other C7041R upstream from the hot
deck zone dampers. Position the thermistors to sense the
average deck temperature.
