3.Mount the outdoor air enthalpy sensor inside the right economizer hood on the right side panel of the hood, adjacent to the outdoor-air thermistor.

4.Locate the red, violet, and brown wires near the out- door air thermistor. Remove the splice from the red and violet wires. Remove the cap from the brown wire.

5.Install a 1¤4-in. push on terminal (®eld-supplied) on the violet and brown wires.

6.Connect a 1¤4-in. push on terminal (®eld-provided) to one end of a 18-gage, 6-in. jumper wire (®eld-provided). Con- nect the other end to the red wire and attach a 1¤4-in. push on connector (®eld-provided).

7.Connect the red wire with the jumper to terminal TR1. Connect the jumper to terminal 2. Connect the brown wire to terminal TR. Connect the violet wire to termi- nal 3. All connections are on the enthalpy control.

8.Replace the economizer ®lters.

9.Return power to unit.

Accessory Differential Enthalpy Control (Fig. 26)

The control (HH57AC077), in conjunction with the accessory enthalpy sensor (HH57AC078), controls economizer opera- tion according to the differential enthalpy. The control is mounted in the economizer hood. The sensor is mounted in the return duct (580G) or the return air plenum (580H).

Differential Enthalpy Sensor Installation

To install the control, perform the following procedure:

1.Turn off all power. Ensure disconnect is locked out.

2.Remove the economizer inlet ®lters from the bottom of the right hand economizer hood.

3.Remove the factory-installed, 620-ohm jumper be- tween terminals SR and + on the enthalpy control located inside the outdoor air hood.

4.Connect the violet wire from the enthalpy sensor kit to the + terminal on the enthalpy control. Connect the blue wire from the enthalpy sensor kit to the SR terminal

on the terminal control.

NOTE: Switches shown in high enthalpy state. Termi- nals 2 and 3 close on enthalpy decrease.

5.Turn the enthalpy control set point potentiometer clock- wise past the ``D'' setting on the enthalpy control to con- ®gure the control to operate on differential enthalpy.

6.Remove the return-air enthalpy sensor from the acces- sory package. Using the screws provided, mount the sensor inside the return duct near the unit. Do not locate the control too far from the unit, or the wires will not reach from the sensor to the control. On 580H units, the enthalpy sensor can be installed in the return air section of the unit, under the return air dampers.

7.Route the wires from the enthalpy sensor to the return air enthalpy control through the holes on the inside of the hinged ®lter access panel. The holes are blocked by plug buttons which should be removed.

580G specifications

The Bryant 580G is a high-efficiency gas furnace designed to deliver optimal heating performance while maximizing energy savings. This model stands out in the Bryant product lineup due to its advanced features and robust technology, making it a popular choice for homeowners seeking reliable comfort in colder climates.

One of the key characteristics of the Bryant 580G is its efficiency rating. With an annual fuel utilization efficiency (AFUE) of up to 92.1%, this furnace ensures that a substantial portion of the fuel consumed is converted into heat, minimizing energy waste and reducing utility bills. This high-efficiency performance is particularly beneficial for those looking to lower their environmental footprint and operate a more sustainable home heating system.

The 580G uses a two-stage heating process, which allows it to operate at two levels of output. During mild weather, the furnace can run on a lower setting, providing gentle warmth while conserving energy. When temperatures drop, the system automatically ramps up to a higher output to maintain comfort. This feature not only enhances energy efficiency but also helps to eliminate temperature fluctuations, ensuring consistent warmth throughout the home.

Noise reduction technology is another remarkable aspect of the Bryant 580G. Equipped with a variable speed blower motor, this furnace operates quietly, providing a more peaceful indoor environment. The motor allows for customizable airflow, which further aids in maintaining an even temperature across different rooms and spaces.

The furnace is built with high-quality materials and features a compact design, making it a suitable option for various installation locations. Additionally, it is compatible with Bryant’s EcoNet Smart Home Management System, which enables homeowners to monitor and control their heating system remotely via a smartphone app. This integration enhances convenience and allows for timely adjustments to heating schedules, promoting energy savings.

Safety is a priority with the 580G. It features an integrated safety switch and a reliable flame sensor to ensure safe operation. With its durable construction and thoughtful engineering, the Bryant 580G is designed to withstand the demands of everyday use while providing peace of mind to homeowners.

In summary, the Bryant 580G gas furnace combines high efficiency, advanced technology, and user-friendly features. Its ability to operate quietly, adapt to temperature changes, and integrate with smart home technology makes it a leading choice for efficient home heating solutions. This furnace not only provides comfort but also offers long-term energy savings, making it a smart investment for any household.
