Honeywell 84209 Thermostat Cable 18 Awg 10 Conductor 250 Ft

Product Description

The Honeywell 84209 is an 18 AWG, 10-conductor thermostat cable supplied on a 250-foot spool. It features bare copper conductors with PVC insulation and a PVC outer jacket, rated for Class 2 (CL2) low-voltage wiring applications. The cable carries UL and ETL listings, confirming it meets industry safety standards for thermostat and control wiring. Rated for temperatures from -20 degrees F to 60 degrees F, it is suited for both indoor residential and light commercial HVAC control installations. HVAC technicians and licensed electricians are the primary installers of this product.

This thermostat cable is used to connect thermostats, zone controllers, humidistats, and low-voltage HVAC control devices to air handlers, furnaces, heat pumps, and other equipment requiring multi-conductor low-voltage wiring. The 10-conductor configuration supports complex systems that need dedicated wires for staging, fan control, humidification, dehumidification, or communicating thermostat functions. The 250-foot spool length makes it practical for new construction wiring runs, multi-zone retrofits, and service vehicle stocking.

Key Features

• 18 AWG bare copper conductors for reliable low-voltage signal transmission
• 10 conductors per cable to support multi-stage and multi-function HVAC control wiring
• PVC insulation and PVC outer jacket for durability in typical installation environments
• CL2 rating meets NEC Class 2 circuit requirements for low-voltage control wiring
• UL and ETL listed for compliance with applicable safety standards
• Temperature rating of -20 degrees F to 60 degrees F covers standard HVAC installation conditions
• 250-foot spool provides sufficient length for most residential and light commercial projects

Compatibility

Designed for use as low-voltage thermostat and control cable in residential and light commercial HVAC systems requiring CL2-rated, 18 AWG multi-conductor wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrician in accordance with NEC Article 725 governing Class 2 and Class 3 remote-control circuits. Always de-energize the HVAC system and thermostat circuit at the breaker before pulling or terminating cable. Avoid routing thermostat cable in the same conduit or bundled with line-voltage wiring. Verify local code requirements for concealed or exposed low-voltage wiring before beginning the installation.
