Temperature Control – Control Systems

Windy City Wire supplies purpose-built, low-voltage temperature control wire and cable for modern control systems. From controller trunks to sensor, actuator, and FIELD DEVICE terminations, our U.S.-made SmartWire products help contractors, integrators, and facility teams deploy reliable BAS and DDC infrastructure with fewer callbacks and faster installs.

SmartWire is our registered brand of low-voltage cable manufactured in the United States. Every SmartWire construction in this category is designed for control signals and low-voltage power-limited circuits commonly used in BAS, DDC, RS-485, BACnet MS/TP, Modbus, Lon, and related control networks.

Why SmartWire for control systems

Built for signal integrity: Low-capacitance options and consistent twist lay support stable RS-485 and other control signaling over longer runs in BAS and DDC applications.
Right shielding for the environment: Options include individually shielded pairs and overall foil shields (O/A) to reduce noise from VFDs and other electrical equipment.
Code-compliant pathways: Plenum (CMP/CL3P) and non-plenum (CM/CMR/CL3) constructions help you match cable to space type and specification.
Installation efficiency: SmartWire Glide lubrication is applied during manufacturing to reduce pulling friction by up to 70%, helping crews finish more pulls with less effort.
Better inventory control: FastFIND Footage Markers appear every two feet to simplify footage calculations, confirm delivered quantity, and reduce waste across projects.
Color identification: Broad jacket and stripe color options support standardized identification schemes across sites and trades. Ask us about custom colors to match your organization’s standards.
Low-voltage focus: All SmartWire offerings in this category are engineered for low-voltage control work.

Solutions: Temperature Control - Control Systems

Temperature Control – Control Systems

Windy City Wire supplies temperature control wire and cable engineered for reliable communication, power-limited control, and sensor connectivity across Building Automation Systems (BAS) and Direct Digital Control (DDC) networks. From network trunks to field-level terminations, our constructions help reduce noise, support longer runs, and simplify installation in commercial and industrial environments.

Designed for leading control platforms

Seamless use across major control ecosystems including Trane, Honeywell, Alerton, Johnson Controls, Siemens, Schneider Electric, Carrier, Delta Controls, and Distech Controls.
Support for common protocols and topologies: BACnet MS/TP over RS‑485, Modbus RTU, LonWorks (Lon), and sensor/actuator home runs. For IP-based controllers and supervisory devices, plenum-rated Category cabling options help support BACnet/IP segments and device connectivity.
Low-capacitance shielded pairs help maintain signal integrity on longer RS‑485 trunks and zone buses, reducing retransmissions and service calls.

Where temperature control cabling is used

Air handlers, rooftop units, boilers/chillers, heat pumps, cooling towers, and energy recovery systems
VAV/VVT boxes, terminal units, damper and valve actuators, and relay interlocks
Room thermostats, wall modules, space sensors (temp, humidity, CO2), and pressure transducers
Supervisory controllers, plant controllers, and integration panels for BAS and DDC
Equipment monitoring, metering interfaces, and network backbones for central plants and mechanical rooms

Industries and facilities we serve

Cable constructions that match the application

Signal and control pairs: 22 and 24 AWG twisted, shielded low‑capacitance pairs are well‑suited for BACnet MS/TP, Modbus RTU, Lon trunks, zone buses, and sensitive sensor circuits.
Power‑limited control: 18, 16, 20, and 14 AWG conductors available for longer runs, higher current draw on actuators, or multi‑device daisy chains where voltage drop must be minimized.
Shielding choices: Overall foil shields (OAS) and unshielded (UNS) options let you balance noise immunity with flexibility and cost. Shielding is recommended in high-interference areas, near VFDs, and in dense mechanical spaces.
Plenum and non‑plenum: CMP/CL3P plenum cables for air-handling spaces; CMR and CM non‑plenum options for general pathways where code allows. RoHS compliance supports modern specification requirements.
Pair counts and multi‑conductor: From 1‑pair sensor runs to multi‑pair or multi‑conductor designs for combined control and monitoring. Individually shielded pairs are available where cross‑talk must be minimized.
Direct‑burial options: For outdoor sensors, remote equipment pads, and site networking between buildings when conduit is impractical.
TFN insulation: Select 600‑volt TFN constructions for specific control circuits and equipment interconnects when required by the design.
Data connectivity: Plenum‑rated Category 5e and Category 6 options for controllers and supervisory equipment using Ethernet or BACnet/IP.

How to choose the right temperature control wire and cable

Match the protocol: For RS‑485 (BACnet MS/TP, Modbus) or Lon trunks, choose 22–24 AWG twisted, shielded, low‑capacitance pairs to maintain signal integrity on longer runs.
Plan for distance and load: Use larger gauges (18, 16, 14 AWG) for actuator power leads or long home runs to reduce voltage drop and maintain device performance.
Consider the environment: Use CMP/CL3P in plenum spaces, CMR where acceptable, and direct‑burial for outdoor pathways. Add shielding in areas with VFDs, generators, or dense power distribution.
Organize by function: Dedicate pairs for supervisory trunks, FIELD DEVICE terminations, and sensor leads to simplify commissioning and service.
Plan for growth: Where future devices are expected, select multi‑pair or multi‑conductor cables to minimize future pulls and downtime.

Application highlights by subsystem

Supervisory trunks: Shielded, low‑capacitance 22–24 AWG twisted pairs for BACnet MS/TP and Lon controllers on Trane, Honeywell, and Alerton networks.
Zone and terminal devices: 22–24 AWG pairs for thermostats and room modules; 18–16 AWG for damper/valve actuators and relay control where current draw is higher.
Plant equipment: Shielded pairs for sensor signals (temperature RTDs/thermistors, pressure) and multi‑conductor cables for pump/VFD interlocks and status circuits.
IP controllers: Plenum Category cable for BACnet/IP and controller‑to‑switch connections in ceiling spaces and mechanical rooms.
