RELAY INSTALLED
A relay can be installed as shown below to switch fan speed to the next lower speed on a call for
dehumidification from the thermostat. The reduction in air flow allows the coil to remove more humidity
from the air. The relay should be rated for the blower motor load. Since this configuration reduces
the air flow in cooling, the anti-freeze-up control or equivalent is recommended to prevent the air
conditioning coil from freezing due to low air flow, dirty filters, low refrigerant pressure, etc.
