Appendix – Fan Speed Configuration
The inline fans included with the CERV can be configured to help maximize comfort and fresh air
delivery to the home. There are three configuration settings for the inline fans:
•
Normal Operation : This will be the default fan speed for the system as it ventilates,
recirculates, heats, and cools your home. In Recirculation Heating and Recirculation Cooling
modes, the outside fan may increase to a higher speed to help boost the efficiency and
capacity of the CERV.
•
Triggered Ventilation : If a wireless switch is pressed to trigger a ventilation period, the fans
will increase to the Triggered Ventilation fan speed setting. This fan speed setting also applies
if you start a timed ventilation event from the wireless controller.
•
Scheduled Recirculation : When no heating, cooling, or ventilation is needed, but the
Scheduled Recirculation setting is greater than 0%, the inside fan will recirculate air throughout
the home. This fan speed setting allows you to recirculate at a higher or lower airflow than
normal operation.
The user may also specify a supply/exhaust fan balance setting for the system. If the fan balance
setting is nonzero, the exhaust fan will run higher or lower than the supply fan while ventilating in
order to compensate for ducting losses for balanced ventilation. For example, if the user sets a -10%
fan balance, and the “Normal Operation” fan speed is 50%, if the CERV is ventilating due to VOC or
CO2 levels, the supply fan to the home would run at 50%, and the exhaust would run at 40%. With a
+10% fan balance, the supply would be 50% and exhaust would be 60%.
