Switches 8 and 9 - Cooling Mode Blower Speed-
The unit is shipped from the factory with the DIP switches
positioned for high speed (4) indoor blower motor operation
during the cooling mode. The table below provides the
cooling mode blower speeds that will result from different
switch settings.

Adjustment -
The unit is shipped from the factory with the
DIP switches positioned for NORMAL (no) adjustment. The
DIP switches may be positioned to adjust the blower speed
by +10% or -10% to better suit the application. Table 18
provides blower speed adjustments that will result from
different switch settings. Refer to air flow tables for values.
With switches 10 an 11 set to ON, motor will bypass ramping
profiles and all delays and will immediately run at selected
COOLING speed upon a call for cool. LED will continue to
operate as normal. This mode is used to check motor
operation.

Ramping -
Blower speed ramping may be used to enhance
dehumidification performance. The switches are factory set
at option A which has the greatest effect on blower motor
performance. Table 19 provides the cooling mode blower
speed ramping options that will result from different switch
settings. The cooling mode blower speed ramping options
are detailed below.
NOTE:
The OFF portion of the selected ramp profile only
applies during heat pump operation in dual fuel applications.

Ramping Option “A” (Factory Selection)
•
Motor runs at 50% for 30 seconds.
•
Motor then runs at 82% for approximately 7-1/2
minutes.
•
If demand has not been satisfied after 7-1/2 minutes,
motor runs at 100% until demand is satisfied.
•
Once demand is met, motor runs at 50% for 30
seconds then ramps down to stop.
Ramping Option “B”
•
Motor runs at 82% for approximately 7-1/2 minutes. If
demand has not been satisfied after 7-1/2 minutes,
motor runs at 100% until demand is satisfied.
•
Once demand is met, motor ramps down to stop.
Ramping Option “C”
•
Motor runs at 100% until demand is satisfied.
•
Once demand is met, motor runs at 100% for 45
seconds then ramps down to stop.
Ramping Option “D”
•
Motor runs at 100% until demand is satisfied.
•
Once demand is met, motor ramps down to stop.
