Abstract
Disclosed is a terminal unit for an air conditioning system. The apparatus has a common chamber for primary and secondary air and a throttling valve at the primary air duct connection controlled by a zone thermostat. The terminal unit fan is independently controlled by an air flow sensor located ahead of the throttling valve in order to prevent fan overload.
