Summary: Temperature Control - LG Cables

Temperature Control — LG Cables

Windy City Wire manufactures U.S.-made SmartWire low-voltage cables engineered for dependable performance in building automation and HVAC control. Our Temperature Control — LG Cables are designed for thermostat loops, sensor and actuator runs, controller I/O, and communication between panels and each FIELD DEVICE. If you need temperature control wire and cable that balances flexibility, code compliance, and signal integrity, this product family delivers consistent results on every job.

What to expect from SmartWire Temperature Control (LG) constructions
All options in this category are low-voltage control cables, available across multiple gauges and conductor counts to match common Temp Control applications. Plenum-rated CMP constructions are available for air-handling spaces, with shielded and non-shielded choices to meet noise mitigation requirements. Select items use tinned copper or low-capacitance designs to support cleaner signals over longer runs. Every SmartWire cable includes our SmartWire Glide lubrication, which reduces pulling friction by up to 70% to help shorten install time and minimize re-pulls.

• Application-ready options: Constructions suited for thermostats, VAV boxes, actuators, relays, and controller communications.
• Shielding choices: Shielded (O/A foil) and non-shielded plenum designs to address EMI/RFI in noisy mechanical rooms and risers.
• Material options: Bare copper for broad compatibility; tinned copper and low-capacitance designs for enhanced corrosion resistance and signal performance.
• Color identification: Common conductor color codes available: Black/White; Black/White/Red; Black/Red/White; and Black/White/Red/Green/Brown/Blue for faster terminations.
• Compliance: Plenum CMP and UL listings available on select constructions; RoHS compliant offerings.
• Lengths: 1000 ft standard, with select items also available in 500 ft.
• Available AWGs: 18, 20, 22.

Whether you are wiring a single rooftop unit or a full BAS deployment, our temperature control wire options simplify specification and installation while maintaining signal integrity. Use these SmartWire solutions as your go-to temperature control wire for consistent results from takeoff to closeout.

How Windy City Wire adds value
Contractors and integrators rely on SmartWire for consistent performance, straightforward pullability, and options that match real-world Temp Control needs. Our portfolio covers common gauges and conductor counts, with shielded plenum choices for sensitive runs and non-shielded plenum options when noise is less of a concern. SmartWire Glide lubrication comes standard to reduce pull tension and help protect the cable jacket and conductors during installation. With available color codes and the ability to discuss custom jacket and stripe colors, you can standardize your installations and streamline service work across sites.

Available constructions

• 18 AWG 2 Conductor Bare Copper Shielded Plenum (CMP) Low-Voltage: A control cable staple for thermostats and short analog signal runs where EMI reduction is required. O/A foil shield helps maintain clean signals in plenum spaces.
• 18 AWG 3 Conductor Bare Copper Shielded Plenum (CMP) Low-Voltage: Adds a third conductor for common/return lines in thermostat and controller applications. Shielding provides added noise immunity near motors and drives.
• 18 AWG 6 Conductor Bare Copper Shielded Plenum (CMP) Low-Voltage: Supports multi-point controls, actuators with feedback, and more complex control circuits. Shielding reduces interference across multiple signals in the same jacket.
• 18 AWG 3 Conductor Bare Copper Non-Shielded Plenum (CMP) Low-Voltage: A cost-effective choice for quieter environments and shorter control runs. Suitable for thermostat circuits and general Temp Control wiring in plenum spaces.
• 20 AWG 3 Conductor Bare Copper Shielded Plenum (CMP) Low-Voltage: Thinner profile for easier routing in crowded pathways with the benefit of foil shielding. Ideal for sensor and controller connections requiring EMI mitigation.
• 20 AWG 3 Conductor Bare Copper Non-Shielded Plenum (CMP) Low-Voltage: Efficient option for general control signals where interference is minimal. Frequently used for shorter sensor and relay wiring in plenum areas.
• 22 AWG 2 Conductor Tinned Copper Shielded Plenum Lo-Cap (CMP) Low-Voltage: Low-capacitance construction supports higher signal fidelity over longer runs. Tinned copper improves corrosion resistance; foil shield helps protect low-level signals.
• 22 AWG 3 Conductor Bare Copper Shielded Plenum (CMP) Low-Voltage: A compact, shielded solution for multi-wire sensor and controller terminations. Useful in noisy electrical rooms and shared conduits.
• 22 AWG 3 Conductor Bare Copper Non-Shielded Plenum (CMP) Low-Voltage: Lightweight and flexible for easy handling and terminations. A solid fit for standard thermostat and sensor circuits where shielding is not required.
• 18 AWG 1 Pair Tinned Copper Shielded Plenum (CMP) Low-Voltage: Twisted pair design for balanced signals and precision sensors. Tinned copper and foil shield help maintain stability in extended control runs.

When to choose shielded vs. non-shielded
Use shielded constructions near VFDs, pumps, and large mechanical equipment to limit induced noise on control signals. Non-shielded plenum options are well suited for shorter, less noise-sensitive thermostat and relay connections in duct or air-handling spaces.

Optimize your next project
If you are specifying temperature control wire and cable for an upcoming BAS or HVAC job, SmartWire LG Cables provide a focused selection that aligns with common drawing schedules and device requirements.

Solutions: Temperature Control - LG Cables

Temperature Control – LG Cables

Windy City Wire provides purpose-built temperature control wire and cable engineered for today’s HVAC and building automation environments. From small thermostat loops to networked building management systems, our constructions support reliable communication, sensing, and control across a wide range of OEM platforms, including Trane, Honeywell, Alerton, Johnson Controls, Siemens, Schneider Electric, Carrier, Daikin, LG, and more. Whether you are wiring a single rooftop unit or an entire Temp Control backbone, our options help maintain signal integrity, meet code requirements, and streamline installation.

Where These Cables Are Used

• HVAC equipment and controls: thermostats, RTUs, AHUs, VAV/FPB boxes, fan coils, dampers, and valve actuators
• Sensing and monitoring: temperature, humidity, CO2/IAQ, pressure, and flow sensors
• Plant and equipment control: boiler/chiller interfaces, pumps, heat exchangers, and energy recovery systems
• Control networks and protocols: BACnet MS/TP, Modbus RTU, and other RS-485 style trunks, plus 0–10 V and 4–20 mA analog control signals
• Integration points: relay panels, lighting control interfaces, energy meters, and gateways that tie Temp Control systems into broader BMS platforms

Construction Options That Match the Application

• Multiple gauges for run length and load: 18, 20, and 22 AWG options help you balance voltage drop, distance, and device power needs for both analog and digital control circuits.
• Conductor counts for common control points: Choose 2- or 3-conductor builds for thermostats and sensors, 6-conductor for multi-point devices, and 1-pair constructions where paired wiring is preferred.
• Shielding when you need noise immunity: Shielded and non-shielded options are available. O/A foil shielding helps mitigate EMI/RFI near VFDs, generators, or dense electrical spaces to protect sensitive data and control signals.

How to Select the Right Temperature Control Wire

1. Identify the system and protocol: For Trane, Honeywell, Alerton, and similar BACnet/Modbus networks, consider shielded RS-485 style runs and low-capacitance options for longer trunks.
2. Match gauge to distance and load: Use 18 AWG for longer 24 V control loops or where devices draw higher current; 20 or 22 AWG for shorter or lower-power runs.
3. Choose conductor count wisely: 2-conductor for many sensors and actuators; 3-conductor when you need an additional signal or reference; 6-conductor for multi-function wall modules or combination devices.
4. Decide on shielding based on environment: Select shielded cable near VFDs, generators, and dense electrical rooms; non-shielded may be suitable in quieter environments and shorter runs.
5. Confirm installation space: Use CMP plenum-rated cable in air-handling spaces to meet code and streamline routing.
