Y8150 Fresh Air Ventilation System,
W8150 Fresh Air Ventilation Control
PRODUCT DATA
FEATURES
APPLICATION
The Y8150 Fresh Air Ventilation System, W8150 Fresh Air Ventilation Control provide fresh air to a home. The control operates a fresh air intake damper and, when necessary, activates the main HVAC blower to efficiently meet ASHRAE ventilation rates.
•Designed to help meet local ventilation codes and standards, including ASHRAE 62.2-2010 standard, “Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings.”
•Microcontroller optimizes the air delivery schedule to make efficient use of normal HVAC run times.
•Easy-to-use input dials allow customized ventilation for each installation.
•Test mode that includes immediate feedback to installer to confirm that air delivery requirements of selected ventilation standard are being met.
•Economical supply-only ventilation; works with forced air system.
•Can be used with other equipment, such as an HRV/ ERV, for balanced ventilation.

INSTALLATION
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.
•Humid climates may require additional dehumidification equipment.
Choosing a location…
When choosing locations for equipment, duct connections, and fresh air intake, be sure to consult local code requirements.
