1. Bonitron A\C Demand Scheduler Alex Brown Cory Haugh Ajmer Dwivedi

2. Purpose of Project Create A/C demand scheduler to reduce peak demand Important because pricing of electricity is a function of both the amount and the peak usage By scheduling the largest loads in a building (the air conditioners) to never run simultaneously peak power can be greatly reduced

3. Previous Group’s Work Created schematic of outdated circuit Created Logic Diagram for Microcontroller Implemented Logic on Altera FPGA Made Functional Prototype

4. Work Required Fit entire circuit into previous designs box –Create custom PCB layout –Use cheap small microcontroller to replace large FPGA board Reduce cost by eliminating 1000$ FPGA prototyping board Add additional features –LCD display for visual input and verification –Serial port to connect to computer monitoring station

5. Previous Group’s Prototype

6. Current Status Met with Keith Benson to identify project specifications Read previous groups work and schematics to understand circuits function Identified DigiKey part numbers and pricing for all currently used parts Identified replacement microcontroller to replace FPGA board
