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, T775-SENS-

STRAP)

The 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 ft. (0.9

m) of the boiler. See Fig. 6.

NOTE: Insulation around the contact area increases

sensor accuracy.
