Remote switch is on • Adjust remote switch to desired position. Thermostat Fan switch is in On position • Normal operation. HVAC system is running to satisfy heating or cooling requirements. • Normal operation. Ventilation limit is set to 100% ventilation limit. • Set ventilation limit to 60%. The control may not be able to meet the recommended ventilation requirements. • Increase ventilation airflow through fresh air duct and adjust settings. Low ventilation air flow. • See Problem: Not enough airflow. • Damper does not open during checkout or • Damper does not close. Incorrectly wired. • Check wiring connections per appropriate wiring diagram. Transformer output. • Verify 24 Vac applied to actuator. Damper actuator motor failure or mechanical failure. • Manually open damper and verify free movement; damper should return to closed position when no power is applied. • If damper moves freely but does not operate when 24 volts is applied, replace damper actuator. • If damper does not move freely, replace fresh air damper. Cooling compressor comes on when there is no cooling call from the thermostat. Incorrectly wired. • Check wiring connections per appropriate system diagram. • An isolation relay may be required when appliances are connected to the GT terminals on the ventilation control. (For an example, see wiring a fan for a steam humidifier diagram.) Not enough airflow Obstruction or duct size • Check for obstructions in the fresh air duct and weather hood. • Check for kinks in ductwork. • Make sure all manual dampers are fully open. • Make sure the stops on the EARD damper allow it to open fully. • Increase duct size. • Add a booster fan to the fresh air duct. NOTE: After any changes to the ductwork, repeat the Measuring Airflow section. 9 68-0282—07 Y8150 FRESH AIR VENTILATION SYSTEM, W8150 FRESH AIR VENTILATION CONTROL 68-0282—07 10 WIRING DIAGRAMS Consult thermostat Installation Instructions for alternate terminal designations.
