Abstract At C-E Power Systems, an operating group of Combustion Engineering, Inc., Windsor, CT, the lighting and HVAC in six of 24 buildings are now under microprocessor control, and the necessary equipment to convert two additional buildings before the year end has been ordered. The initial analysis of the economic benefits of a /100,000 investment for the first six buildings showed the system will pay for itself in electricity savings in 30 months or less. In the programmable lighting system, a microprocessor-based central controller is /left double quote/softwired/right double quote/ to a single-chip microcomputer-based local transceiver. The data line provides a high integrity communications channel carrying multiplex commands from the central controllers as well as status and switch override message from the remote transceivers. The controller has the capacity to direct as many as 500 transceivers controlling 8,000 relays.
