Honeywell 84206 Thermostat Cable 18 Awg 7 Conductor 250 Ft

Product Description

The HONEYWELL 84206 is an 18 AWG, 7-conductor thermostat cable designed for low-voltage control wiring in residential and light commercial HVAC systems. Constructed with bare copper conductors and a PVC jacket, this cable delivers reliable signal transmission between thermostats, air handlers, furnaces, heat pumps, and other control equipment. The CL2 rating makes it suitable for in-wall routing per code requirements. Packaged as a 250-foot spool, it provides enough run length for most new-construction or retrofit installations without mid-run splices.

This cable is used primarily in residential and light commercial HVAC installations where multiple control wires are needed to support multi-stage heating, cooling, fan, and auxiliary heat functions. The 7-conductor configuration handles systems requiring common, heat, cool, fan, second-stage, and auxiliary or reversing-valve signals. HVAC technicians and low-voltage electricians typically specify this cable for thermostat runs, zone control boards, and humidifier or ventilator wiring.

Key Features

• 18 AWG bare copper conductors for consistent low-voltage signal integrity
• 7 conductors support multi-stage and heat pump control wiring configurations
• CL2-rated for compliant in-wall and concealed installation
• PVC insulation and jacket rated from -20 to 60 degrees F for broad environmental tolerance
• 250-foot spool length reduces the need for splices on longer thermostat runs
• UL and ETL listed for recognized safety compliance

Compatibility

Designed as a standard 18 AWG CL2 thermostat cable suitable for low-voltage HVAC control wiring applications including thermostats, zone boards, air handlers, furnaces, and heat pump systems requiring up to 7 conductors.

Installation Notes

Installation should be performed by a licensed HVAC technician or low-voltage electrician in accordance with the NEC and local codes governing CL2 wiring. Power down the HVAC system at the disconnect or breaker before pulling or terminating any control wiring. Route cable away from high-voltage wiring and heat sources, and secure runs with appropriate low-voltage staples or cable supports. Strip conductors carefully to avoid nicking the bare copper, which can cause intermittent faults at terminal connections.
