How does a VFD work?
Using zone flap controls set to individual thermostats, the zones will open and close based on the need for demand heating/cooling. If both zones require heat, then the vent controls will be open to supply flow to those zones. If one zone is turned off, the zone damper will close. This increases the system pressure. Normal furnaces will continue to run at the same speed using excess energy. With the Arctic Air Handler, the static pressure sensor senses an increase in pressure as a result of a closed zone and immediately turns down the RPM reducing the CFM and reducing operating costs as well as excess fan noise.
