START

Is LED status light on?

YES

Is LED status light blinking rapidly without a pause?

NO

Is LED status light blinking ON/OFF slowly with a combination of short and long flashes?

YES

Determine status code. The status code is a 2 digit number with the first digit determined by the number of short flashes and the second digit by the number of long flashes?

NO

To recall status code briefly remove and reconnect one RED wire from the draft

 

safeguard switch to display stored status code. On RED LED control do not

 

 

remove power or blower access panel before initiating status code recall. You

can also recall the previous status code by momentarily shorting the TEST/TWIN terminal to Com24V terminal until the LED goes out. LED will flash the status code of the previous fault or status code #11 (1 short and 1 long flash) if there was no previous fault. After the control repeats the code 4 times, the control will go through a brief component test sequence. The inducer will start and run for the entire component test. The HSI, blower motor FAN speed (AMBER LED boards only) HEAT speed, and COOL speed will run for 10 – 15 seconds each. Gas valve and humidifier will not be turned on.

NO

Is door switch closed?

NO

Is circuit breaker closed?

YES

NO

Check for continuity in wire from circuit breaker to furnace.

Close circuit breaker and go back to START.

Check room thermostat or

interconnecting cable.

NO

Run system through a heating or cooling cycle to check operation. Status codes are erased after 72 hours. On RED LED boards stored status codes can also be erased whenever (115V or 24V) is interrupted.

Replace furnace control.

NO

Is 24V present at W, Y1 (if present), Y/Y2 or

 

G thermostat terminals on the furnace control?

YES

Disconnect all the thermostat wires from the furnace control.

YES

Does the problem repeat when using

 

a jumper wire?

 

 

NO

 

 

 

 

 

The thermostat is not compatible with the furnace control. Either install a ballast resistor, connect the Com24V thermostat terminal to the thermostat, or replace the thermostat.

310JAV, 310AAV specifications

The Bryant 310AAV and 310JAV are high-efficiency air conditioning and heating systems designed for residential and light commercial applications. These models embody Bryant's commitment to delivering reliable comfort solutions while prioritizing energy efficiency and performance.

One of the standout features of the Bryant 310AAV and 310JAV is their impressive Seasonal Energy Efficiency Ratio (SEER) ratings. The higher the SEER, the more efficient the unit is in using electricity to cool your space. The Bryant 310AAV boasts a SEER rating of up to 16, while the 310JAV offers a slightly lower rating. This efficiency translates into cost savings on monthly energy bills while ensuring indoor comfort throughout the year.

Both models utilize advanced technologies, including two-stage heating and cooling capabilities. This means that the systems can adjust their operation based on the heating or cooling needs of a space, providing optimal temperature control while reducing energy waste. The two-stage operation also contributes to quieter operation levels, making these units suitable for residential settings where noise is a concern.

The 310AAV and 310JAV are equipped with variable-speed compressors, which further enhance their efficiency and comfort levels. The variable-speed technology allows the system to operate at different speeds, ensuring consistent temperature management and reducing the frequency of on-and-off cycling. This leads to steadier indoor temperatures and improved humidity control.

In addition to their performance features, Bryant places a strong emphasis on durability and dependability. The units are constructed with high-quality materials that are designed to withstand various environmental conditions. Features such as a weather-resistant cabinet and an efficient coil design help protect the units from wear and tear, ensuring long-lasting performance.

The implementation of environmentally friendly refrigerant options is another characteristic that demonstrates Bryant's commitment to sustainability. Both the 310AAV and 310JAV utilize R-410A refrigerant, which has a lower environmental impact compared to older refrigerants, aligning with modern standards for eco-friendly HVAC systems.

Overall, the Bryant 310AAV and 310JAV represent a blend of efficiency, advanced technology, and durability. With their attractive SEER ratings, two-stage operation, variable-speed capabilities, and commitment to sustainability, these models stand out as excellent choices for homeowners and businesses looking to enhance their heating and cooling solutions while keeping energy consumption in check. Whether for residential comfort or light commercial use, these Bryant units promise reliability and performance for years to come.
