The following procedures include outdoor, duct, immersion well and strap-on applications. Also refer to the instructions for the electronic control. 4 (70) Outdoor Mounting (C7031G, C7021F, C7023F, C7041F) The C7031G, C7021F, C7023F and C7041F sense outdoor air temperature. Mount this control where it can sense average outdoor air temperature. Normally, the north side of a building provides a suitable location. 4 THERMISTORS PLACED ON A 12 FOOT (3.7M) WIRE. NOTE: These sensors are weatherproof for outdoor use. Knockouts allow for 1/2 in. conduit connection. M22133 Fig. 10. C7021J, C7023J, C7031J, C7041J dimensions in in. (mm). 3. 4. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application. Installer must be a trained, experienced service technician. After installation is complete, check out product operation as provided in these instructions. 63-2590—05 Make wiring connections using two wire nuts. Reattach the wiring box cover. Duct Mounting When Installing this Product... 2. Remove and set aside the wiring box cover. Mount the sensor to standard 1/2 in. conduit. NOTE: Mount sensor so that the element points down. 3. 4. INSTALLATION 1. 1. 2. 8 The C7031B, C7031J, C7021B/C/J, C7023B/C/J, C7041B/C/J can be mounted in a duct to sense air temperature. IMPORTANT Select a spot for the sensor where it will be exposed to average duct air temperature. Avoid locations where stratification can cause sensing errors. C7021B,C/C7023B/C, C7041B/C MOUNTING 1. Cut a hole in the duct just large enough to accept the sensing element. 2. Use the sensor case to mark the locations of the pilot holes for the mounting screws. 3. Drill the pilot holes and fasten the sensor to the duct. SERIES 2000 ELECTRONIC TEMPERATURE SENSORS 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.

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.

The C7021D, C7023D, and C7041D sensors do not include a well. For the C7021D, C7023D, and 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. makes contact before mounting (remove insulation from the pipe at the point of installation if necessary). Thermal compound is recommended with the strap-on C7021K, C7023K, C7041K Sensor. Locate the sensor on the discharge pipe within 3 feet (0.9m) of the boiler. See Fig. 16. SENSOR COPPER PLATE MUST MAKE GOOD CONTACT WITH METAL PIPE In other installations, mount the immersion well in an elbow with a heel outlet as shown in Fig. 15. 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. WORM GEAR Mount the C7021D, C7023D, C7031D and C7041D into the well: 2. 3. M22136 Fig. 16. Strap-on mounting of C7021K, C7023K, C7041K Sensor. NOTE: Mounting using previously installed Honeywell wells (part no.: 32005960-001) requires an adapter (part no.: 50001775-001). 1. PIPE When an adapter is required, first thread it into the well no more than one or two turns. Slide the sensor into the well. Rotate the sensor to thread it tightly into the adapter and the adapter tightly into the well. NOTE: Insulation around the contact area increases sensor accuracy. Button Probe Mounting The C7021P, C7023P, C7041P Button Probe Sensor design simplifies mounting into a variety of standard structural materials. The locking nut can be used to secure the probe. See Fig. 18. SENSING ELEMENT (SEALED IN STAINLESS STEEL TUBE INSIDE OF INSERTION WELL) The plastic spacer helps insulate the probe from drywall, wood, or other material in which the probe is mounted. The spacer is sized to fit snugly into 1/2 in. metal conduit. See Fig. 17. 1/2 NPT (13) NOTES: — — M22135 Fig. 15. Method of mounting C7021D, C7023D, C7031D, C7041D Sensor. The plastic spacer is threaded for easy installation. Use of both the locking nut and spacer requires cutting spacer to shorter length. C7041P MOUNTING RECOMMENDATIONS Determine the proper location based upon the following: — Mount the probe to an inside wall approximately 54 in. (1372 mm) from the floor (or in the specified location) to allow exposure to the average zone temperature. — Do not mount the probe to an outside wall, a wall containing waterpipes, or near air ducts. — Avoid locations exposed to register discharge air, or radiation from lights, appliances, or the sun. Strap-On Mounting (C7021K, C7023K, C7041K) Strap-on mounting is well-suited for retrofit applications where installation costs can be reduced by not draining the system. The C7021K, C7023K, C7041K Sensor mounts on metal pipes from 1-5/8 inch to five inches in diameter using the straps supplied. Clean the surface of the pipe where the sensor 63-2590—05 10 M22797 Fig. 17. Mounting sensor in conduit. SERIES 2000 ELECTRONIC TEMPERATURE SENSORS CAUTION Electrical Shock or Equipment Damage Hazard. Can shock individuals or short equipment circuitry. Disconnect power supply before installation. WALL IMPORTANT 1. All wiring must agree with applicable codes, ordinances and regulations. 2. Do not mount sensor in incorrect environment. 3. Wire according to the applicable controller instructions. OPERATION AND CHECKOUT Operation M22799 The C7041 Temperature Sensors are designed for use with XL500, XL100, XL50, XL15, XL10, and Honeywell LCBS Controllers or any controller requiring 20K ohm NTC non-linear input. As the temperature at the C7041 Sensor increases, the resistance of the sensor decreases, causing the controller to operate and offset the temperature change. Fig. 18. Mounting sensor in wall with nut only. Bullet Probe Sensor Mounting (C7021N, C7023N, C7041N) The bullet probe sensor is a water-resistant sensor that provides a cost-effective solution for surface contact temperature measurement of conditioned water pipes, low pressure steam or refrigerant lines. These sensors are ideal for applications where immersion wells are not practical to install. These sensors can also be use to sense air temperature. WIRING The C7021 Temperature Sensors are designed for use with the TB7600, TB7300, and TB7200 Series Communicating Thermostats or any controller requiring a 10K ohm NTC Type II input. The C7023 Temperature Sensors are designed for use with WEBs-AX I/O Modules or any controller requiring a 10K ohm NTC Type III input. Checkout Refer to the applicable controller instructions when checking out the complete heating and cooling systems. CAUTION Erratic System Operation Hazard. Failure to follow proper wiring practices can introduce disruptive electrical interference (noise). Keep wiring at least one foot away from large inductive loads such as motors line starters, lighting ballasts, and large power distribution panels. Shielded cable is required in installations where these guidelines cannot be met. Ground shield only to grounded controller case. 11 To check out the sensors, move the thermostat or remote setpoint potentiometer below the temperature of the cooling or heating medium. Watch the motor, valve or damper for the correct movement. 63-2590—05 SERIES 2000 ELECTRONIC TEMPERATURE SENSORS Automation and Control Solutions Honeywell International Inc. 1985 Douglas Drive North Golden Valley, MN 55422 customer.honeywell.com ® U.S. Registered Trademark © 2011 Honeywell International Inc. 63-2590—05 M.S.
