ABSTRACT:
The environmental control system of the present invention is used in a multiple room structure which includes independently actuatable heating and cooling devices in each room. This system operates by monitoring the ambient air temperature in each room and by controlling the operation of each heating and cooling device to achieve a desired ambient air temperature in each room. The structure of the present invention includes a room status indicator which indicates the occupied or vacant status of each room. A centrally located control panel permits an operator to assign heating mode and cooling mode temperature limits to each room. A temperature sensing and control unit is positioned in each room and is coupled to the heating and cooling device in each room. The temperature sensing and control unit measures the ambient room air temperature, determines the operating mode of the heating and cooling device and controls the operating mode of the heating and cooling device in response to a control signal. A central processor is coupled to the room status indicator, to the control panel and to each of the temperature sensing and control units to continuously monitor and control the operation of each room heating and cooling device to achieve the desired ambient room air temperature in each room.
