Air Temperature Sensors

APPLICATION

The C7046 series of Air Temperature Sensors function 
as primary and/or secondary sensors in electronic control 
systems.

INSTALLATION

When Installing this Product...

1.

Read these instructions carefully. Failure to follow 
them could damage the product or cause a hazard-
ous condition.

2.

Check the ratings given in the instructions and on 
the product to make sure the product is suitable for 
your application.

3.

Installer must be a trained, experienced service 
technician.

4.

After installation is complete, check out product 
operation as provided in these instructions.

CAUTION

Electrical Shock or Equipment Damage 
Hazard.
Can shock individuals or short equipment 
circuitry.

Disconnect power supply before installation.

The sensor assembly (see Fig. 1) consists of an 
aluminum sensor probe (element housed internally) with 
attached flange that can be mounted on a flat duct or 
plenum surface, or in a 2 in. by 4 in. (51 by 102 mm) 
junction box using two No. 8 screws. Connections to the 
sensor are made through two 6 in. (152 mm) leadwires.

Fig. 1. C7046A,B,C,D Air Temperature 

Sensor dimensions in in. (mm).

NOTE: Sensor probe diameter is 1/4 in. (6 mm).

Location

The sensor should be located in the air duct or plenum 
where it will sample an average air temperature. Avoid 
locations where air stratification can cause sensing 
errors.

Mounting

Mounting on Flat Duct or Plenum Surface (Fig. 2)

1.

Cut a 3/8 in. (9.5 mm) hole in the duct or plenum 
surface at the desired location.

2.

Insert sensor probe into the duct or plenum until 
the flange rests against the duct or plenum wall.

3.

If necessary, use the flange as a template to mark 
and drill two holes for No. 8 mounting screws.

4.

Fasten the sensor to the duct or plenum surface 
with two No. 8 sheet metal screws (not provided).

Mounting in a Junction Box (Fig. 3)

1.

Cut a 3/8 in. (9.5 mm) hole in the duct or plenum         
surface at the desired location. 

2.

Remove the center rear knockout from the junction 
box and insert the sensing probe through the 
knockout with the flange flat against the outlet box. 

3.

Using the flange as a template, mark and drill two 
holes in the junction box and the duct or plenum 
surface for No. 8 mounting screws.

4.

Insert sensor probe through both the junction box 
knockout and the 3/8 in. (9.5 mm) hole drilled in the 
duct or plenum and fasten the junction box and 
sensor to the duct or plenum surface.
