Configuring the Fixed Speed Blower

The fixed speed blower assembly has been designed to

give the installer maximum flexibility for optimizing system

performance, efficiency, and comfort. It is equipped with

a microprocessor-controlled motor when coupled with a

fixed speed motor control board delivers constant torque

to optimize airflow in a variety of conditions and system

configurations. Because the blower can be configured in

many ways, it is important to read and follow all instructions

carefully.
Upon initial start up, the fixed speed blower must be

checked so that the factory settings match the unit with

the system, climatic conditions, and other system options.

With the blower installed and configured properly, the

furnace will change speed in response to changes in

system variables such as Heat/Cool setting, Fan Auto/

On, or 2 Stage furnace High/Low Heat. The fixed speed

blower is configured by setting the 8 switches for heating

and cooling operation located on the blower control board.

Use pins 1 to 4 to set the blower speed for heating and

pins 5 to 8 to set the speed for cooling. To determine the

appropriate switch settings for your installation, see

for heating or

Table 8 for cooling. See

Figure 10 (page 36)

for switch

locations.

NOTE:

For change in blower speed selection to

take effect, system power must be cycled off then restored

after 10 seconds.
Selecting Cooling Airflow

(Switches # 5, 6, 7, & 8)
The COOLING airflow is selected by setting switches # 5,

6, 7, & 8 on the motor control board (

Figure 10

Table 8

(page 28)

lists the recommended airflow values (CFM)

and switch settings for each nominal cooling system

capacity. All airflows for other modes of operation are

determined by these basic settings. For maximum capacity,

generally, a selection near the middle or top of the CFM

range for that nominal capacity is used. Factory settings

are displayed in BOLD ITALICS
Selecting Heating Airflow

(Switches # 1, 2, 3, & 4)
The HEATING airflow is selected by setting switches #

1, 2, 3, & 4 on the motor control board (Figure 10, Page

31).

list the recommended airflow values (CFM) and switch

settings for each heat exchanger capacity. All airflows are

determined by these basic settings. For most applications

the factory heat setting will operate at a nominal rise based

on the furnace’s nominal efficiency and firing input. Follow

across the table row to find the switch setting and nominal

air-flow. Verify the selected rise is within the specification

shown on the furnace rating label or in the tables.

Dehumidification Options

The fixed speed motor control board has a

DEHUM

connection that allows the system to increase the amount

of humidity that is removed from the circulating air. This

is accomplished by reducing the CFM and allowing the

cooling coil to become colder. This function is only available

when there is a call for cooling. There are many ways this

function can be electrically wired.
When 24VAC is present at the

DEHUM

terminal of the

blower control board the airflow requirements will be

reduced to approximately 75% of the nominal airflow

requirements. If the humidity level of the conditioned space

decreases during the cycle and the humidistat opens, the

airflow will be restored to 100% of the selected value.
• If the room thermostat incorporates a humidity sensor

and

DEHUM

output, connect the

DEHUM

on the

thermostat to the

DEHUM

terminal on the motor control

board. See

Figure 10 (page 36)

• If using a separate humidistat, connect the

DEHUM

terminals on the humidistat to the

DEHUM

terminals

on the motor control board. In this option, the

DEHUM

output of the humidistat must be set to be normally open

and closed when there is a call for dehumidification.

If a humidistat is not available, it is an acceptable option

to directly jumper the

DEHUM

on the blower control

board.

NOTE:

This option will always operate the blower

at 75% the rated airflow for the first 10 minutes of every

cooling cycle no matter what the humidity level of the

home is. See

Figure 10

CAUTION:

To avoid personal injury or property damage,

make sure the motor leads do not come into

contact with any uninsulated metal components

of the unit.

Optional Furnace Control Board Connections

Electronic Air Cleaner

The furnace control board provides output terminals

for an optional electronic air cleaner (EAC) that can be

installed in the return air duct of your system. The

EAC

output is energized any time the HEAT or COOL blower

speed is energized. Control ratings are 1.0 Amp. @ 240

VAC. Output connections are made via board terminals

labeled

EAC

and

NEUTRAL

Humidifier

The furnace control board provides output terminals for

an optional humidifier (

HUM

) that can be installed on

your system. The

HUM

output is energized any time the

furnace inducer motor is energized. Control ratings are

1.0 Amp. @ 240 VAC. Output connections are made via

board terminals labeled

HUM

and

NEUTRAL

Check all factory wiring to the proper unit wiring diagram:

Figure 13 (page 37)

. Inspect the factory wiring

connections and make sure they didn’t loosen during

shipping or installation.
