SETTING BLOWER
TIMINGS
NOTE: This does not apply to these
models. The heat tap functions as the
continuous fan tap as well.
See Figure 49 for instructions for
setting the blower "OFF" timings.
If cooling speed and fan speed are
desired to be the same, this may be
accomplished by not connecting "Y"
to the integrated furnace control.
If desired for cool, fan and heat to all
be the same speed, then "piggyback"
jumper "H/C" to "FAN" and do not
connect "Y" to the integrated furnace
control. Do not connect anything to
"H" or "C."

The blower motor is wired for blower
speeds required for normal operation
as shown.
If additional blower speed taps are
available, speeds may be changed if
necessary to fit requirements of the
particular installation. Check motor
lead color for speed designation.
Heating speeds should not be
reduced where it could cause the
furnace air temperature to rise to
exceed the maximum outlet air
temperature specified for the unit.
IMPORTANT: Always check air
temperature rise after changing the
heating speed for any reason.
