Dry
The dry setting is best suited to parts of the country where excessive
humidity is not generally a problem, where the summer months are usu-
ally dry. On a call for cooling the motor will ramp up to full capacity and
will stay there until the thermostat is satisfied. At the end of the cooling
cycle, the blower will ramp down to 50% of full capacity where it will stay
for 60 seconds. Then it will ramp down to zero.
Temperate
The temperate setting is best suited for most of the country, where nei-
ther excessive humidity nor extremely dry conditions are the norm. On
a call for cooling, the motor will ramp up to 63% of full capacity and will
stay there for 90 seconds, then will ramp up to full capacity. At the end
of the cooling cycle, the motor will ramp down to 63% of full capacity
and will stay there for 30 seconds, then will ramp down to zero.
