Summary: Temperature Control - Siemens Cables

Temperature Control – Siemens Cables

Windy City Wire manufactures SmartWire low-voltage temperature control wire and cable that meets the demands of Siemens Building Technologies environments. This category focuses on Siemens Temp Control applications, including controller I/O, 24 VAC power/control loops, actuators, sensors, and BACnet MS/TP communications. Our SmartWire products are made in the United States, are plenum-rated for code compliance in air-handling spaces, and are available with shielding and conductor configurations that align with Siemens control strategies and device requirements.

Built for reliable Siemens Temp Control performance

• Plenum-rated and listed for code compliance: Options include CMP and CL3P listings to address common specifications for temperature control installations in commercial facilities.
• Signal integrity for communications: Low-capacitance shielded twisted pairs support longer runs and stable BACnet MS/TP trunks, helping reduce noise in dense building automation spaces. (Also searchable as Bacnet.)
• Shielding options to fit the job: Choose Non-Shielded, Shielded, or Each Pair Shield (EPS) constructions to match device type, run length, and EMI environment.
• Easier pulls: SmartWire Glide lubrication is applied during manufacturing and reduces friction by up to 70% during installation, helping crews work faster with fewer re-pulls.
• Better material management: FastFIND Footage Markers appear every two feet to make measurements quick, help verify received length, and reduce waste by 15–25% across projects.

Lengths and availability

• Standard length: 1000 ft
• Additional length available on select items: 2500 ft
• All products in this category are low-voltage temperature control wire and cable.

Color identification

To simplify terminations and field identification, conductor color codes include options such as Black/White, Black/White/Red, White-Blue/Blue, White-Orange/Orange, Pair – Black/White, and Single – Yellow. SmartWire also offers a wide selection of jacket and stripe colors to help standardize your organization’s installs.

System compatibility

Whether you refer to it as Siemens or SBT wire and cable, SmartWire constructions align with common Siemens control and communication requirements, from 24 VAC device power and control loops to BACnet MS/TP zone bus communications. This helps streamline submittals, procurement, and installation for both retrofit and new construction.

2. 18 AWG 3 Conductor Bare Copper Plenum CMP: Adds a third conductor for shared commons or additional signal needs in Siemens controller and actuator circuits. Suitable for plenum installations where a non-shielded cable is specified.
3. 24 AWG 1 Pair Tinned Copper, Shielded Plenum Low-Cap CL3P/CMP: Low-capacitance twisted pair with overall shield for BACnet MS/TP or other Siemens zone bus communication lines. Designed to help maintain signal integrity over longer runs in air-handling spaces.
4. 24 AWG 1.5 Pair Tinned Copper, Shielded Plenum Low-Cap CL3P/CMP: One twisted pair plus an additional conductor supports devices that need a spare or auxiliary signal lead, often found in wall sensors and room units. Shielding helps reduce interference in noise-prone pathways for Siemens or SBT wire and cable applications.
5. 24 AWG 2 Pair Tinned Copper, Each Pair Shielded (EPS) Plenum Low-Cap CL3P/CMP: Two low-capacitance twisted pairs with each pair individually shielded for superior crosstalk and noise control. Ideal for BACnet trunks, multi-drop communication lines, or parallel signals in larger Siemens control networks.
6. 14 AWG 2 Conductor Bare Copper Plenum CL3P: Heavier gauge option for longer 24 VAC power runs or higher-current actuators in plenum spaces. Non-shielded construction for general control and power distribution to field devices.

Solutions: Temperature Control - Siemens Cables

Temperature Control – Siemens Cables

Windy City Wire supplies temperature control wire and cable engineered for reliable performance in Siemens Building Technologies environments and other leading building automation systems. This category supports a wide range of Temp Control applications—from device power and control to network communications—using plenum-rated constructions (CMP/CL3P) that meet modern code requirements for commercial and institutional facilities. If you’re searching for siemens or sbt wire and cable that is proven in the field, this selection delivers the right balance of gauge options, shielding, and low-capacitance designs for dependable BAS performance.

Where these cables are used

• Room and zone devices: thermostats, temperature and humidity sensors, CO2 sensors, and wall modules
• HVAC equipment: VAV boxes, fan coil units, RTUs, AHUs, boilers, chillers, and heat pumps
• Field devices: damper and valve actuators, relays, end switches, and contact closures
• Controller-to-controller and controller-to-device communication buses, including BACnet MS/TP (Bacnet) and other RS‑485 based networks

Designed for multi-system environments

While optimized for Siemens BAS platforms, these Temp Control cables are also used across Trane, Honeywell, Johnson Controls, Schneider Electric, and Alerton systems. Whether you’re wiring discrete control circuits or a shared communications trunk, the available constructions support common BAS topologies and protocols, including BACnet MS/TP (Bacnet) and Modbus RTU for RS‑485 field buses.

Applications by cable type

• 18 AWG, 2-conductor, non-shielded (plenum): General control wiring for thermostats, relays, damper/valve actuators, and sensor power where shielding isn’t required.
• 18 AWG, 3-conductor, non-shielded (plenum): Adds a conductor for applications needing a common or additional signal lead—frequent in mixed sensor/control circuits or actuator control with feedback.
• 24 AWG, shielded, low-capacitance (1, 1.5, or 2 pair): Purpose-built for communication lines such as BACnet MS/TP trunks, controller links, and other RS‑485 data runs. Pair shielding helps reject electrical noise near VFDs, lighting ballasts, and power cabling, while low capacitance supports longer distances and cleaner signals.
• 14 AWG, 2-conductor, non-shielded (plenum): Ideal when longer runs and higher current draw are expected—for example, supplying power to multiple actuators or high-torque devices on a circuit while managing voltage drop.

Why spec these cables

• Plenum-rated safety and compliance: CMP and/or CL3P listings for use in environmental air spaces, aligning with typical commercial BAS installations.
• Signal integrity options: Shielded, low-capacitance pairs for stable data transmission on shared networks and long runs.
• Multiple gauges to match the run: Choose 24 AWG for data pairs, 18 AWG for standard control, and 14 AWG for higher current or longer distances.
• Color coding for quick identification: Options include Black/White, Black/White/Red for control; and White-Blue/Blue, White-Orange/Orange for paired communications—useful during install and service.
• Jacket color options: Blue and orange selections can help distinguish control from communications pathways in the field.

Integrations and use cases

• Siemens and SBT platforms: Suitable for controller IO, actuator runs, and zone bus links on Desigo and legacy SBT systems.
• Trane, Honeywell, Alerton, and others: Supports typical control points and RS‑485 communications used by these ecosystems.
• Network protocols: Well-suited for BACnet MS/TP (Bacnet) and Modbus RTU field buses; shielding and low-capacitance constructions help maintain network stability.

Industries and facility types

• Commercial offices and mixed-use buildings
• Healthcare, labs, and life sciences facilities
• Higher education, K–12, and campuses
• Hospitality, retail, and multifamily
• Industrial, warehouse, and logistics spaces
• Data centers and mission-critical environments

Spec and selection tips

1. Match gauge to distance and load: Use 14 AWG when longer runs or higher actuator loads are present to minimize voltage drop; 18 AWG for typical device control; 24 AWG pairs for data lines.
2. Use shielding where noise is present: Near VFDs, generators, or dense power distribution, shielded low-capacitance pairs help protect RS‑485 communications.
3. Maintain pair integrity: Keep twisted pairs intact for data lines, observe polarity, and follow controller manufacturer guidance for terminations and biasing.
4. Separate from power: Maintain recommended separation from high-voltage and high-current conductors to reduce interference.
5. Plan for identification: Select color codes and jacket colors that align with your site standards for faster commissioning and service.
