Switches 9 and 10 -- Cooling Mode Blower Speed
Ramping -- Blower speed ramping may be used to en-
hance dehumidifi cation performance. The switches are
factory set at option A which has the greatest effect on de-
humidifi cation performance. Table 9 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.

• Motor runs at 50% for 30 seconds.
• Motor then runs at 82% for approximately 7-1/2 min-
utes.
• If demand has not been satisfi ed after 7-1/2 minutes,
motor runs at 100% until demand is satisfi ed.
• Once demand is met, motor runs at 50% for 30 sec-
onds then ramps down to stop.

Switches 11, 12 and 13 -- Heating Mode Blower Speed
The switches are factory set to the OFF position which
provides factory default heat speed. Refer to Table 10 for
switches 11, 12 and 13 that provided the corresponding
increases or decrease to both high and low heat demand.
