ABSTRACT:
An improved thermally actuated diffuser is disclosed. The diffuser comprises three thermal sensor actuators. A first thermal sensor actuator is responsive to changes in the room air temperature and is engaged when cool air is supplied through the duct into the room. A third thermal sensor actuator is responsive to changes in the room air temperature and is engaged when warm air is supplied to the room. A second thermal sensor actuator is responsive to changes in the duct air temperature and brings either the first or second thermal sensor actuator into engagement with the diffuser when the appropriate temperature of air is supplied through the duct and disengages the thermal actuator not being used with that duct air temperature.
