VENTILATION / FAN CYCLING SETTINGS (CONTINUED)

This installed option allows outside air to be combined with the fan cycling feature from the dehumidifier, provided the outside air temperature is in the acceptable range (0-100°F). Note: The dehumidifier can control the HVAC fan to provide fan cycling, regardless of whether or not an outdoor ventilation duct is installed.

•An Aprilaire® Normally-Closed Damper (Model 6506) should be installed in the outside air intake. It should be wired to the terminals labeled “VENT DAMPER” on the dehumidifier control board. Follow all installation instructions supplied with the damper. Refer to each installation for ducting.

•The Outdoor Temperature Sensor (Model 4278) should be installed outside in a shaded location (Figure 16) or in an outside air intake duct, but no more than 3 feet from the outside (Figure 17).

•The Outdoor Temperature Sensor is not affected by wire length. However, do not route the wire alongside wires carrying high voltage (115 VAC or greater), as interference may occur.

1.Based on ASHRAE 62.2 ventilation requirement.

2.Based on outside air duct of 6” dia., 20’ long flex duct, 0.15” w.c. static pressure at outdoor air duct.

3.Based on ‘Cycle Period’ being in the default (1 hour) position.

4.A longer outside air duct and/or lower static pressure will require a longer Ventilation Time.

As an example, for a 2,500 square foot home with 3 bedrooms, set the cycle time to 30 minutes of ventilation per one-hour cycle.

A longer outdoor air intake duct or lower return static pressure will increase the ventilation time required. Additionally, local codes may affect the setting.
