to a level which causes the Thermidistat™ to close its contacts. When the contacts close, the airflow will return to 100 percent of selected cooling airflow. To activate this mode wire in Thermidistat™ see jumper in Fig. 10.

e.DEHUMIDIFY AND SUPER DEHUMIDIFY CAPABILITIES

This model unit is capable of responding to a signal from Thermidistat™ to operate in comfort control modes such as Super Dehumidify Mode. Consult literature provided with Thermidistat™ to determine if these operating modes are available, and to see control set up instructions. No special setup or wiring of unit is required.

F.683B Sequence of Operation

a.CONTINUOUS FAN

(1.) Thermostat closes circuit R to GÐThe Blower runs at continuous fan airflow

b.COOLING MODE

(1.) If indoor temperature is above temperature set point and humidity is below humidity set point, thermostat closes circuits R to G, R to Y/Y2 and R to OÐThe unit delivers single speed cooling airflow.

c.COOLING MODE-DEHUMIDIFICATION

(1.) If indoor temperature is above temperature set point and humidity is above humidity set point, Thermidistat™ closes circuits R to G, R to Y/Y2, R to O and Thermidis- tat™ opens R to DHÐThe unit delivers airflow which is approximately 80 percent of the nominal cooling airflow to increase the latent capacity of the system.

d.COOLING MODE-SUPER DEHUMIDIFY OPERATION (SEE QUICK REFERENCE GUIDE)

NOTE: Thermidistat™ is capable of providing Super Dehu- midify operation mode and must be configured as outlined in its installation instructions. Consult indoor control literature to deter- mine if control is capable of providing Super Dehumidify inputs and for configuration instruction.

(1.) If the indoor temperature is below the temperature set point and the humidity is above the humidity set point, the Thermidistat™ closes circuit R to O, opens circuits R to DH and R to G, and closes circuit R to Y/Y2. If circuit R to G is closed (24-v.), the motor will deliver airflow at the full cooling or cooling plus dehumidify mode requested 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. GAS HEATING MODE

(Occurs if outdoor temperature is below outdoor temperature change over setpoint.)

(1.) Thermostat closes circuit R to W/W1ÐThe unit delivers the selected gas heat airflow. The IGC will control 45 sec. on delay with no airflow and 45 sec. off delay.

f. HEAT PUMP HEATING MODE

(Occurs if outdoor temperature is above outdoor temperature change over setpoint.)

(1.) Thermidistat™ closes circuit R to G and R to Y/Y2±The unit delivers selected heat pump heating airflow.

g. HEATING MODEÐSUPER COMFORT HEAT OPERA-

TION

Ð7Ð

NOTE: The Thermidistat™ is capable of providing Super Com- fort Heat operation mode and must be configured as outlined in its installation instructions. The system must be installed with appro- priate outdoor temperature sensor. Consult Thermidistat™ litera- ture for configuration instructions. Consult 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.

EASY SELECT™ CONFIGURATION TAPS FOR 702B & 602B

Easy Select™ taps are used by the installer to configure a system. The ICM motor uses the selected taps to modify its operation to a pre-programmed table of airflows.

The unit must be configured to operate properly with system components with which it is installed. To successfully configure a basic system (see information printed on circuit board label located next to select pins), move the 6 select wires to the pins which match the components used.

a. AUX HEAT kW/CFMÐSELECT HEATER RANGE FOR SIZE OF ELECTRIC HEATER INSTALLED

Installer must select the auxiliary heat airflow approved for application with kW size heater installed. If no heater is installed, this step can be skipped. Each select pin is marked with a range of heaters for which airflow (also marked), is approved. For increased comfort, select the narrowest kW range matching the heater size, for example, 0±10 for 10±kW heater. This airflow must be greater than the minimum for CFM for electric heater application with the size system installed for safe and continuous operation. (See Tables 16, 17 & 18 for airflow delivery and minimum CFM.) Note that airflow marked is the

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.
