VENTILATION (continued)

VENT-AUTO & VENT-TIMED

The dehumidifier can ventilate in four modes.

Vent-Timed: Ventilation occurs based only on time setting; no temperature restrictions..

Vent-Auto-B: Ventilation prevented when outdoor temperature is below 0°F and above 100°F.. Between 0°F – 20°F ventilation is only allowed during a HVAC heat call..

Vent-Auto-C: Ventilation prevented when outdoor temperature is below 0°F and above 100°F..

Vent-Auto-D: Ventilation prevented when outdoor temperature is below 0°F and above 90°F.. Between 0°F – 40°F ventilation is only allowed during a HVAC heat call..

Vent-Auto-B, -C, -D modes apply outdoor temperature limits and require an outdoor temperature sensor to be installed..

OUTDOOR TEMPERATURE SENSOR INSTALLATION

The Outdoor Temperature Sensor should be installed outside in a shaded location, or in the outdoor air intake duct..
