Ventilation
The dehumidier can activate a normally closed damper
to bring in outdoor air through a fresh air intake duct. This
feature can not be used when a Y6456 has been installed
in a Remote Control application, and is not recommended
for two-zone installations.
Required Components
X4152 Ventilation Damper – 6 in. Normally Closed (NC)
6" Insulated Duct for Fresh Air Intake Duct
22N03 (24 VAC, 40 VA) 24 VAC Transformer for
Ventilation Damper
Intake Hood
18-22 AWG Wire
Optional Component
58N66 Outdoor Temperature Sensor
INSTALLATION & WIRING
VENT-AUTO & VENT-TIMED
The dehumidier 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 the 58N66 Outdoor Temperature
Sensor to be installed.
