ContinuousFan Operation
A terminal is provided on the electronic fan control located in the
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 op-
eration.
Separate speed selections for Heat, Cool, and Continuous
Fan
Connect low speed lead from circulating motor to the "Cont." ter-
minal at the electronic fan 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 be-
tween the "Heat" and "Cont." terminals on the electronic fan con-
trol.
Note: There should be only ONE motor lead going to the "Heat"
and "Cont." terminals.
