INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to
follow them could damage the product or
cause a hazardous 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.
Mounting
The mounting method depends on the particular sensor
application. The following procedures include:
— duct applications
— outdoor applications
— immersion well applications
— strap-on applications
NOTE: Also refer to the instructions for the electronic
control.
Duct Mounting (C7041B,C)
IMPORTANT
Select a spot for the sensor that will exposed it to
average duct air temperature. Avoid locations
where stratification can cause sensing errors.
1. Cut a hole in the duct just large enough to accept
the sensing element.
2. Use the sensor’s case to mark locations of pilot
holes for the mounting screws.
3. Drill pilot holes and fasten the sensor to the duct.
Fig. 1. C7041B,C dimensions in in. (mm).
Outdoor Mounting (C7031G, C7041F;
T775-SENS-OAT)
The outdoor air temperature sensors have a weather-
proof enclosure. Mount the sensor where it can sense
average outdoor air temperature. All mounting hardware
is provided with the sensor. Be sure to mount the sensor
out of direct sunlight with the sensor probe point down.
Normally, the north side of a building provides a suitable
location.
NOTE: C7031G, C7041F, and T775-SENS-OAT are
weatherproof for outdoor use. Knockouts allow
for 1/2 in. conduit connection.
1. Remove and set aside the wiring box cover.
2. Mount the sensor to standard 1/2 in. conduit.
NOTE: Mount sensor so that the element points
down.
3. Make wiring connections using two wire nuts.
4. Reattach the wiring box cover.

Immersion Well Mounting (C7031D, C7041D)
NOTE: The C7041D uses the 50001774-001 Well
Assembly. See Fig. 5 for dimensions.
The C7031D Sensor includes an immersion well. The
C7041D Sensor does not include a well. For the C7041D,
order the well as an accessory (part no.: 50001774-001).
When used on a boiler, follow the manufacturer
instructions for location. If a tapped hole is not provided
for the immersion well, provide one as follows:
1. Drain boiler and drill a 23/32 in. (18 mm) hole at the
selected location.
2. Cut threads in the hole with a 1/2 in. (13 mm) by
14 NPT tap.
In other installations, mount the immersion well in an
elbow with a heel outlet as shown in Fig. 3.
1. Drain the system, if you have not already done it,
and open the tapped hole.
2. Put pipe joint compound on the threads of the
immersion well and screw it into the tapped hole or
elbow, tightening it securely.
3. Refill the system and check for leaks.
Mount the C7031D/C7041D into the well:
NOTE: Mounting using previously installed
Honeywell wells (part no.: 32005960-001)
requires an adapter
(part no.: 50001775-001).
1. When an adapter is required, first thread it into the
well no more than one or two turns.
2. Slide the sensor into the well.
3. Rotate the sensor to thread it tightly into the adapter
and the adapter tightly into the well.

Strap-on Mounting (C7041K)
The C7041K Sensor mounts on metal pipes from
1-5/8 inch to five inches in diameter using the straps
supplied. Clean the pipe surface where the sensor makes
contact before mounting. If necessary, remove pipe
insulation at the installation point. Thermal compound is
recommended. Locate the sensor on the discharge pipe
within 3 feet (0.9m) of the boiler. See Fig. 6.
NOTE: Insulation around the contact area increases
sensor accuracy.
