Abstract: An environment control system permitting the occupant of a room or space in a multi-room building sharing a common air supply conduit with other rooms to control the environment in his or her room selectively and/or automatically. The system =includes a small wireless portable remote control unit readily accessible to the occupant for selecting predetermined conditions. These conditions are transmitted to a remote receiver which provides signals to a main control unit coupled to external environmental control units such as motors which operate damper valves in the room, air conditioning units supplying air to the common conduit heaters within the room and the like. Both the remote control unit and the main control unit include a programmed microcontroller. The portable control unit may be used to select the desired environmental conditions within the room while the lights are on and transmits this information to the main control unit which acts to energize and deenergize the external control units.

Abstract: An air flow control system for the dampers of the individual offices or rooms in a group of offices or rooms sharing a common air supply duct with a thermostatic control in but a single one of the offices or rooms. The system includes a motor operated damper in each room or office, the motor being controlled to shut the damper when a signal from a remote transmitter is received by a receiver in a control circuit with the motor. The transmitter is selectively actuated by the individual occupying the particular room or office. The control circuit is activated when the signal is received by the receiver, and after a delay period automatically sends a signal to drive the motor to reopen the damper. The occupant may thus control the closing of the damper when the temperature of the air through the supply duct causes the room to be uncomfortable, and need not be concerned about reopening the damper.
