Limited Warranty; Thank You - Aprilaire 1720 Installation,Safety & Maintenance Manual

VENTILATION OR FAN CYCLING SEQUENCE OF OPERATION
If the dehumidifier is providing outdoor air ventilation or fan cycling, it is monitoring the HVAC equipment to provide the amount
of HVAC fan run time that has been set by the Cycle Time during the Cycle Period.
If an outdoor air damper has not been installed then the dehumidifier is providing fan cycling. The dehumidifier will monitor the
HVAC system and if the system has not run for the specified Cycle Time within the Cycle Period, the dehumidifier will energize
the HVAC fan through the G terminal to provide the desired amount of fan run time.
For example, if the Cycle Time is set for 10 minutes and the Cycle Period is set for 1 hour then the dehumidifier will provide
10 minutes of fan cycling or outdoor air ventilation. If the HVAC system runs for 5 minutes during this hour then the dehumidifier
will energize the fan for an additional 5 minutes.
If an outdoor air damper has been installed, then the Model 1720 is providing outdoor air ventilation. The 1720 will open the
outdoor air damper whenever the HVAC system is running, up to the amount of time specified by the Cycle Time. The
dehumidifier will energize the HVAC fan and open the outdoor air damper to provide the desired ventilation time if the HVAC
system has not run for the specified Cycle Time.
If an Outdoor Temperature Sensor has been installed, then the dehumidifier will use the outdoor temperature to determine if the
outdoor air damper is to be opened. If the outdoor temperature is above 100°F the damper will not open. If the temperature is
between 20°F and 0°F the damper will only open with a heat call. If the outdoor temperature is below 0°F, the damper will not
open. If the Outdoor Temperature Sensor is not installed then the temperature is not considered in opening the damper.
