A fresh air duct and damper must be installed between the
outdoors and the return side of the HVAC equipment. The
W8150 control will be mounted near the HVAC system and
wired between the thermostat and the fan control.
You will need…
• W8150 Fresh Air Ventilation Control.
• damper.
• transformer.
• insulated ductwork.
• outdoor weather hood.
• starting collar.
• access to 120 Vac power.
• airflow measuring tool.
TIPS:
• To meet ASHRAE 62.2-2010, system must have at least a
MERV 6 filter installed.
• In cold climates, balanced ventilation is recommended. An
exhaust fan or heat recovery ventilator can be used.
