Temperature Control Shielded Cables

Summary: Temperature Control Shielded Cables

Temperature Control Shielded Cables

Windy City Wire manufactures low-voltage SmartWire cables engineered for building automation and HVAC temperature control. In modern BAS networks that combine analog sensors with digital communications, dependable shielded control cabling is essential for stable readings and uninterrupted device communication. Our temperature control wire and cable portfolio covers plenum and non‑plenum installations, single and multi-conductor constructions, and paired and triad options to support thermostats, VAV boxes, actuators, controllers, and supervisory systems.

Whether you are running conventional control loops or integrating BACnet MS/TP and Modbus segments, our shielded constructions help reduce electrical noise and maintain signal integrity over long runs. For serial bus requirements, many customers also select from our shielded options for RS485/422 networks as well as rs 232 wire and cable connections within mechanical rooms and control panels. All products in this category are low-voltage SmartWire cables made in the United States.

Why shielding matters in temperature control

Controls wiring often runs near VFDs, lighting circuits, and power feeders. Our shielded constructions—available as overall shielded and individually shielded pair options—help reject EMI/RFI and maintain stable signals for 0–10 VDC, 4–20 mA, thermistor loops, and digital communications. This can reduce nuisance noise, improve sensor accuracy, and support dependable network performance where rs-485 wire and cable or rs485 wire and cable is required.

Cable options to match your spec

Ratings for the space: Plenum-rated selections (e.g., CMP and CL3P) for environmental air spaces, plus riser and general-purpose control options (e.g., CMR and PLTC) for non-plenum pathways. Select the rating appropriate to each pathway and jurisdiction.
Conductor sizes: Broad AWG range—14, 16, 18, 20, 22, and 24 AWG—to balance distance, voltage drop, and device requirements.
Conductor counts: From 2–12 conductors, as well as 1–3 pair and triad constructions, to accommodate everything from a simple thermostat loop to multi-point VAV controls or sensor/actuator bundles.
Shielding choices: Overall foil shields for general noise protection and individually shielded pairs for sensitive analog signals or when combining signal types under one jacket.
Lengths: Available in 1000 ft and select 500 ft lengths to help align spool sizes with your project pull plan and reduce scrap.

Compatibility with common control platforms

Trane, Honeywell, Alerton, Johnson Controls, Siemens, Schneider Electric: Sensor loops, actuator runs, and controller I/O wiring for zones, air handlers, plant equipment, and terminal units.
Carrier, Daikin, VRF/VRV platforms: Indoor unit control, outdoor unit communication trunks (per manufacturer wiring diagrams), and gateway links into the BAS.
Automated Logic, Distech, Delta Controls, Niagara-based systems: Controller-to-controller trunks, supervisory links, and panel I/O wiring where RS485/422 signaling is used.
Legacy/auxiliary links: Where older serial interfaces are present, options are available that align with rs 232 wire and cable practices.

Typical control applications

Thermostat and wall module home-runs to unit controllers
VAV box wiring: actuator, reheat, discharge air temp, and differential pressure sensors
Hydronic valve/damper actuator control and end-switch feedback
Sensor networks: space, duct, water, and outdoor temperature; humidity; CO2
Controller-to-controller MS/TP or Modbus RTU trunks over RS485/422

Performance and installation advantages

Signal integrity: Foil shielding helps maintain clean signals in electrically noisy rooms and mechanical spaces.
Code-ready: Plenum and non-plenum options let you match rating to pathway without over-specifying materials.
Right-sizing the run: Multiple AWGs and conductor counts help manage voltage drop and future expansion while minimizing oversized cable costs.
Project flexibility: Select multi-conductor or multi-pair designs to consolidate pulls and reduce conduit fill on dense control points.

Digital controls and BAS networking

For modern BAS trunks, choose constructions suited to RS485/422 to support BACnet MS/TP and Modbus RTU. Correct impedance, shielding, and grounding practices are essential for network reliability—especially across long runs or when parallel to power feeders. Our temperature control wire and cable options are designed to support these requirements and help you maintain consistent, verifiable performance.

Streamlining on-site workflows

Pairing these cables with our SmartWire approach can help crews organize zone runs, speed device terminations, and simplify testing and turnover across large projects—assisting with consistent results from rough-in through commissioning.

Selecting the right cable

Confirm the space rating required (plenum vs. non-plenum)
Match AWG and conductor count to device power/data needs and distance
Choose shielding level (overall vs. individually shielded pairs) based on noise exposure and signal type
For network trunks, align with protocol guidance (e.g., RS485/422) and manufacturer recommendations
Choose 1000 ft or 500 ft lengths based on pull distances and waste reduction goals
