BEDROOMS M22009 Ventilation Limit* Ventilation Standard 1 2 60% ASHRAE 62.2 100% 62-1999 Setting ventilation limit and ventilation standard. 68-0282—07 6 Y8150 FRESH AIR VENTILATION SYSTEM, W8150 FRESH AIR VENTILATION CONTROL Y8150 FRESH AIR VENTILATION SYSTEM, W8150 FRESH AIR VENTILATION CONTROL 1. Be sure power is turned on. 2. Set the Ventilation Standard on the control. 3. Set the bedrooms dial. 4. Set the area (sq ft) dial. 5. Set the airflow (cfm) dial. 6. Press the test button and observe the lights: Green light is flashing. The dial settings meet the chosen standard. Red light is flashing. There is not enough fresh air delivered to meet the requirements of the selected standard. See Troubleshooting section. 7. Record settings on the label inside the cover as shown in the diagram. TIPS: • Ventilation control reads new dial setting only when test button is pushed or power is cycled. To ensure dial settings are read, push test button after any changes are made. • For single bedroom homes, set the bedrooms dial to 2 (this may result in more ventilation than the minimum required). • For homes having more than five bedrooms and only a single ventilation system, set the bedrooms dial to 5 (this may result in less ventilation than the minimum required). • For conditioned square feet, set area (sq ft) dial to the nearest value. • For airflow, set airflow (cfm) dial to the nearest value. • Vaulted ceilings do not need to be considered when setting this control. • For homes with multiple systems: Honeywell recommends a ventilation control and fresh air intake for each system. Measure ventilation airflow for each system independently. Refer to Multi-system Setup Example for further details. Honeywell Golden Valley, MN 55422 50001159-001 Rev.

On thermostat, set Fan switch to Auto and System switch to Off. 2. Set any remote switches throughout the house in the Off position. 3. On the W8150, set the control switch to Off (remote only). 4. Press Test button for two seconds to enter test mode: • A light on the control begins flashing. • The HVAC system fan comes on. • The damper moves to the Open position. 5. Press the Test button again to exit test mode: • No lights on the control are on. • The HVAC system fan turns off. • The damper returns to the closed position. 6. Return the thermostat, ventilation control, and remote switches to the original settings. 7. Refer to Troubleshooting section, if needed. TROUBLESHOOTING Problem Possible cause What to do Flashing red light during test mode Not enough airflow • Measure airflow and check dial setting. • See Problem: Not enough airflow. (The current settings do not meet the selected ventilation requirement) Ventilation on-time limit setting • If the device is set to 60%: Set the ventilation control to 100% maximum on time. This allows the HVAC fan to run up to 100% of the time. It may be preferable to increase airflow. • If the device is set to 100%: There is not enough airflow through the fresh air duct. • Ventilation continues to occur according to the settings but chosen standard may not be met. Flashing red light Low voltage • Check the voltage from the transformer for at least 20 Vac. If voltage is during normal OK, replace W8150 Control. If voltage is not OK, disconnect damper and operation remote switch connections and check again. If voltage does not return to at least 20 Vac, replace transformer. No light on ventilation control when switch set to: • On • Override Off/ • Remote Only and a remote switch is on. No power to control • Verify 24 volt input to R and C terminals on ventilation control. • Check wiring connections per appropriate system diagram and replace transformer, if necessary. Device malfunction • Cycle power off to control for ten seconds and recheck. If control does not recover, replace ventilatio...
