1. If any of the original equipment wire is replaced use wire rated for 105°C.
2. Inducer (IDM) and blower (BLWM) motors contain internal auto-reset thermal overload switches (OL).
3. Blower motor speed selections are for average conditions, see installation instructions for details on optimum speed selection.
4. Use only copper wire between the disconnect switch and the furnace junction box (JB).
5. This wire must be connected to furnace sheetmetal for control to detect flame.
6. Replace only with a 3 amp fuse.
7. Yellow lead not on all motors.
8. Blower-on delay, gas heating 45 seconds, cooling or heat pump 2 seconds.
9. Blower-off delay, gas heating 90, 135, 180 or 225 seconds, cooling or heat pump 90 seconds. (135 seconds only on some models)
10. Ignition-lockout will occur after four consecutive unsuccessful trials-for-ignition. Control will auto-reset after three hours.
11. When used, auxiliary limit switch (ALS) is on some downflow models only. When used, FL is on upflow models only.
12. Some models may have spade quick connect terminals.
13. Factory connected when LGPS is not used.
14. Factory connected when BVSS is not used. BVSS used when Chimney Adapter Accessory Kit is installed.
15. Gas valve leads are interchangeable on single stage valves.322869-101 REV. H

58YAV specifications

The Carrier 58YAV is a high-efficiency gas furnace that has gained recognition in the HVAC industry for its performance and advanced technology. Specifically designed to meet the needs of modern homes, the 58YAV integrates various features that enhance comfort, energy efficiency, and reliability.

One of the standout characteristics of the 58YAV is its exceptional AFUE (Annual Fuel Utilization Efficiency) rating, which often reaches up to 96%. This means that the furnace converts a significant portion of fuel into heat, translating into lower energy bills and a reduced carbon footprint. The unit operates using a two-stage heating system which allows for greater temperature consistency and improved energy savings. The ability to operate at a low stage during mild conditions prevents energy wastage while providing adequate heating comfort.

The 58YAV employs advanced modulating technology that provides precise temperature control. This technology enables the furnace to adjust its heating output based on the specific demands of the home, ensuring optimal comfort without unnecessary energy consumption. Additionally, the integrated variable-speed blower motor enhances air circulation and reduces noise during operation, creating a quieter home environment.

Moreover, equipped with a smart thermostat capability, the Carrier 58YAV can be paired with Carrier’s Comfort™ series controls for enhanced programmability and remote access. This feature allows homeowners to conveniently adjust their home’s heating settings from their smartphones or other smart devices, maximizing convenience and control over their indoor environment.

The furnace also features a durable and robust cabinet design that ensures long-lasting performance. With enhanced insulation, the 58YAV minimizes operational noise and provides greater energy efficiency. Safety features, including a pressure switch and flame sensor, are integrated into the system to ensure safe and reliable operation.

In terms of installation, the Carrier 58YAV is designed to offer versatility with multiple venting options, allowing it to fit seamlessly into various home configurations. Its compact design makes it suitable for various spaces, from attics to basements.

Overall, the Carrier 58YAV is a pinnacle of modern heating technology, providing homeowners with efficient, reliable, and smart heating solutions that align with today’s energy standards. Its blend of efficiency, comfort, and innovative features establishes it as a top choice in the gas furnace market.
