value. If circuit R to G is open (0±v.) for super dehumidify mode, the motor delivers reduced airflow to maximize the humidity removal of the system while minimizing over cooling.

e.ELECTRIC HEATING MODE

(1.) Thermostat closes circuit R to W/W1, or W2ÐThe unit delivers the selected electric heat airflow. There are no on or off delays.

f.HEAT PUMP HEATING MODE (602B only)

(1.) Thermostat closes circuits R to G and R to Y/Y2ÐThe unit delivers selected heat pump heating airflow.

g.HEAT PUMP HEATING WITH AUXILIARY ELECTRIC HEAT (602B only)

(1.) Thermostat closes circuits R to G, R to Y/Y2 and R to W/W1 or W2 (and R to O in the case of defrost).

In the event that electric heating is called for by the thermostat while the heat pump is also operating in either heating or defrost modes, the motor will modify its airflow output, if necessary, to provide an airflow which is defined as safe for the operation of the electric heater during heat pump operation. That airflow is the greater of the heat pump heating airflow and the electric heater only airflow.

h.HEATING MODEÐSUPER COMFORT HEAT OPERA- TION

NOTE: The indoor control used, such as a Thermidistat™, must be capable of providing Super Comfort Heat operation mode and control must be configured as outlined in its installation instruc- tions. The system must be installed with appropriate outdoor temperature sensor. Consult indoor control literature to determine if control is capable and for configuration instructions. Consult indoor control instructions and sensor instructions for sensor installation details.

If the outdoor temperature is in the range of 12° to 40° F, the Thermidistat™ closes circuit R to Y/Y2 and opens circuit R to G. If circuit R to G is closed (24-v.), the motor will deliver airflow at the full heating requested value. If circuit R to G is open (0-v.) for maximum heating comfort, the motor delivers reduced airflow to maximize the temperature and minimize the draft effect of the heated air leaving the unit.

CHECKING AND ADJUSTING REFRIGERANT CHARGE The refrigerant system is fully charged with Puron® (R-410A) refrigerant, and is tested and factory sealed.

NOTE: Adjustment of the refrigerant charge is not required UNLESS the unit is suspected of not having the proper R-410A charge.

The charging label and the tables shown refer to system tempera- tures and pressures. The temperatures and pressures are calculated at rated airflow. When charging unit, set to rated airflow. A refrigerant charging chart label is attached to the outside of the compressor access door. The chart includes the required suction line temperature at given suction line pressures and outdoor ambients. An accurate superheat, thermocouple- or thermistor-type thermometer, and gage manifold are required when using the superheat charging method for evaluating the unit charge. Do not use mercury or small dial-type thermometers because they are not adequate for this type of measurement

IMPORTANT: When evaluating the refrigerant charge, an indi- cated adjustment to the specified factory charge must always be very minimal. If a substantial adjustment is indicated, an abnormal condition exists somewhere in the cooling system, such as insuf- ficient airflow across either one or both coils.

CHECKING COOLING CONTROL OPERATION-Start and check the unit for proper cooling control operation as follows:

(1.) Place room thermostat SYSTEM switch in OFF position. Observe that blower motor starts when FAN switch is placed in ON position and shuts down when FAN switch is placed in AUTO position. Note fan delay time setting selected on the Easy Select™ board. (See Easy Select Section.)

(2.) Place SYSTEM switch in COOL position and FAN switch in AUTO position. Set cooling control below room tem- perature. Observe that compressor, condenser fan, and evaporator blower motors start. Observe that cooling cycle shuts down when control setting is satisfied. The evapo- rator fan will continue to run for the time setting selected on Easy Select™ board. (See Easy Select Section.)

(3.) When using an auto-changeover room thermostat, place both SYSTEM and FAN switches in AUTO position. Observe that unit operates in heating mode when tempera- ture control is set to ªcall for heatingº (above room temperature) and operates in cooling mode when tempera- ture control is set to ªcall for coolingº (below room temperature).

AIRFLOW AND TEMPERATURE RISE-The heating section for each size unit is designed and approved for heating operation within the temperature rise range stamped on the unit rating plate. Table 15 shows the approved temperature rise range for each heating input, and the air delivery (CFM) at various temperature rise ranges.

The heating operation airflow must produce a temperature rise that falls with in the approved range.

Refer to Indoor Airflow and Airflow Tables on the following pages to adjust heating airflow when required.

CHECK HEATING CONTROL-Start and check the unit for proper heating control operation as follows. (see furnace lighting instructions located inside burner or blower access panel.):

(1.) Place room thermostat SYSTEM switch in the HEAT position and the FAN switch in the AUTO position.

(2.) Set the heating temperature control of the thermostat above room temperature.

(3.) The induced-draft motor will start.

(4.) After a call for heating, the main burner should light with in 5 sec. If the burners still do not light, this sequence is repeated. If the burners do not light within 15 minutes from the initial call for heat, there is a lockout. To reset the lockout control, break the 24-v. power to W.

(5.) The indoor fan will turn on 45 sec after the flame has been established. The indoor fan will turn off according to time delay selected on the Easy Select™ board (See Easy Select Section) after the thermostat has been satisfied.

Also refer to the Thermidistat™ instructions for start up and check out of the system.

(1.) FAN OPERATIONÐ

The fan button on Thermidistat™ switches fan icon between AUTO and ON. While ON is displayed, output will be on, turning fan on. Allow up to 10 sec. after button is pressed for fan to turn on and off. the fan will continue to run for the time setting selected on the Easy Select™ board after AUTO icon is displayed.

(2.) COOLING MODEÐ

602B, 683B, 702B, 583B specifications

The Bryant 583B is an advanced, high-efficiency gas furnace designed to provide exceptional heating performance and reliability. With a focus on comfort and energy efficiency, this model stands out in the residential heating market.

One of the main features of the Bryant 583B is its impressive Annual Fuel Utilization Efficiency (AFUE) rating of up to 95%. This means that the furnace converts up to 95% of the fuel it consumes into usable heat. As a result, homeowners can expect lower energy bills and reduced environmental impact due to decreased carbon emissions.

The Bryant 583B is equipped with a modulating gas valve that allows for precise control of the heating output. This technology enables the furnace to adjust its running capacity based on the heating demands of your home. Instead of operating at a single, high setting, the furnace runs at the required level to maintain the desired temperature, delivering consistent comfort while maximizing efficiency.

Another noteworthy characteristic of the 583B is its two-stage operation. This feature allows the furnace to operate at a lower stage for mild weather, which reduces energy consumption and minimizes noise levels. During colder conditions, it can switch to a high stage for increased heating capacity. This dual approach not only enhances comfort but also prolongs the lifespan of the unit by reducing wear and tear.

In terms of construction, the Bryant 583B is built with durable materials and a robust cabinet, which ensures longevity and resilience over time. It also comes with a quiet operation feature, minimizing disturbances while maintaining a comfortable indoor environment.

The unit is compatible with Bryant's advanced communication technology, enabling seamless integration with smart thermostats. This addition allows homeowners to monitor and control their furnace remotely, optimizing energy usage even further.

In summary, the Bryant 583B furnishes an outstanding combination of efficiency, reliability, and user-friendly technologies. Its modulating gas valve, two-stage operation, and high AFUE rating collectively ensure that customers enjoy a comfortable home environment while significantly reducing energy costs. As energy-conscious choices become increasingly crucial, the Bryant 583B stands ready to meet the challenges of modern heating needs.
