Furnace Maintenance; Separate Speed Selections For Heat, Cool, And Continuous Fan; Heating And Continuous Blower Speed The Same - Arcoaire N9MP1 Installation Instruction

3. If the same speed must be used for both heating and
cooling, remove the undesired motor speed lead from the
"Heat" or "Cool" terminal and connect that lead to the open
terminal at "Unused Motor Lead" location. Attach a jumper
between the "Heat" and "Cool" terminals and the remaining
motor speed lead.
Note: For motors with (4) speed leads, it will be necessary to
tape off the terminal of the motor speed lead removed from
the "Heat" or "Cool" terminal with electrical tape since an
open terminal will not be available at the "Unused Motor
Lead" location.
Continuous- Fan Operation using "G"
Energizing the "G" terminal on the furnace control provides
continuous fan operation. This is done by connecting the G
terminal of the thermostat to the G terminal on the furnace control.
When the FAN switch is turned from auto to ON the fan will operate
continuously at "HEAT" speed. EAC will be energized in this
mode.
NOTE: In heating, the fan will turn off during furnace ignition and
warm up then restart at heating speed.
Hard Wired Continuous Fan Operation
A terminal is provided on the furnace control board located in the

WARNING
!
FIRE, EXPLOSION,
HAZARD.
Failure to follow this warning could result in
personal injury or death.
It is recommended that the furnace be inspected
and serviced on an annual basis (before the heating
season) by a qualified service technician.

OR CARBON MONOXIDE
Specifications are subject to change without notice
circulating blower compartment for operation of the continuous fan
option. This connection is intended for the low speed motor tap,
and has a lower contact rating (8 amps) than the heat and cool
taps. When the low speed blower lead is connected to this
terminal, this will provide low speed blower operation whenever
the other two speeds (Heat or Cool) are not energized.
Thoroughly check the system after modification to ensure the
proper operation of the circulating air blower in all modes of
operation.
Separate speed selections for Heat, Cool, and
Continuous Fan
Connect low speed lead from circulating motor to the "Cont."
terminal at the furnace control. The appropriate motor leads
should already be connected to the "Heat" and "Cool" terminals.
Heating and Continuous Blower Speed the
Same
If it is necessary to operate the heating speed and continuous
blower speed using the same blower speed, connect a jumper
between the "Heat" and "Cont." terminals on the furnace control.
Note: There should be only ONE motor lead going to the "Heat"
and "Cont." terminals.
WARNING
!
ELECTRICAL SHOCK, FIRE OR EXPLOSION
