Switches 7 and 8 −− Heating Mode Blower Speed −−
Switches 7 and 8 are used to select heating mode blower
motor speed. The unit is shipped from the factory with the
dip switches positioned for medium low (2) speed indoor
blower motor operation during the heating mode. The table
below provides the heating mode blower speeds that will
result from different switch settings. Refer to tables 14
through NO TAG for corresponding L/s values.

N/A − First and second stage HEAT positions shown cannot be used on this model.
NOTES − The effect of static pressure is included in air volumes shown.
First stage HEAT is approximately
91%
of the same second stage HEAT speed position.
First stage COOL (two−stage air conditioning units only) is approximately 70
%
of the same second stage COOL speed position.
Continuous Fan Only speed is approximately
38%
of the same second stage COOL speed position − minimum 500 cfm (235 L/s).
