If configured for a 3-speed fan, the medium fan speed output will energize at step 3. If configured for a 2-speed fan, the fan remains on high speed at step 3.
4
If configured for a 3-speed fan, the medium fan speed output energizes at step 4. If configured for a 2-speed fan, the low fan speed output energizes at step 4. If configured
for a 1-speed fan, the fan remains on high speed at step 4.
5
If the unit is configured for a 1- or 2-speed fan, the exhaust fan output energizes on step 7. The exhaust fan output is shared with medium fan speed.
