Why is there persistent condensation on my SummerAire Fan windows?

  Persistent condensation usually occurs due to improper adjustment of the dehumidistat or an improper ventilation rate. Adjust the dehumidistat to the correct RH reading (see operation manual) or to a lower setting, and check its operation; replace it if defective. Consider installing a dehumidistat in the living area. To address ventilation, ensure the HRV is running continuously, increase the fan speed, and balance the system.

  If the fan speed doesn’t seem to change, it might be due to an improperly installed duct system or incorrect voltage. Ensure the motor amp draw doesn’t exceed the nameplate rating; increased static (i.e., dampening) may be necessary. Measure the line voltage and the voltage to the motor to determine if it’s correct, and confirm that your voltmeter is reading correctly. All voltages must be measured with the duct system installed. The correct voltages are: Low speed 97 volts, Medium speed 105 volts, High speed 120 volts. If the voltages are correct, then the duct system static is too low.

  If you find water in the bottom of the HRV, the drain lines might be obstructed, or the HRV heat exchange core may not be installed correctly. Check the water drain connections and ensure the water drains properly from the pan(s). Also, check the orientation label on the front of the core and position the core correctly. The HRV may also not be level.
