FAQ: Field Installation Best Practices

1. Ensure you have 75F supplied wire and adapters for all SmartNodes/Hyperstats and sensors.
   1. Multisensors, RTH, CTH, DPS, 75F Duct Sensors all require 3-pin cable/3-wire adapters
   2. Hypersense requires 4-pin cable and/or adapters
2. Note the following article for CCU locations to avoid:

3. Install new transformers in electrical rooms, mechanical rooms, inside HVAC equipment, or other locations where the transformers are easily accessible and meet local code.
4. Plan all cable runs prior to beginning.  Keep cable paths parallel to building lines.
5. Run cables in bridle rings or other appropriate cable paths.  Do not strap to fire lines, ceiling tile grid, HVAC equipment, or other items that vibrate or are sharp.
6. Provide bushings for any cable penetrations through sharp objects.
7. Avoid sharing IT cable trays.
8. Homerun all wires.  Splicing will cause sensor communication issues and may void warranty.
9. Zip tie along the way to keep wire from sagging and neat.
10. Zip tie with a loop at each device for stress relief.
11. If reusing thermostat cable, ohm wires to ensure integrity of conductors.
12. Firestop any penetrations as required by code.
13. Electrical equipment and cabling must be installed in a neat and workmanlike manner [Sec. 110.12]
14. Unused openings must be closed by fittings that provide protection substantially equivalent to the wall of the equipment [Sec. 110.12(A) and (C)].

Note: Refer to the National Electric Code (NEC) and your local electrical ordinances.
