Electronic temperature control system
A digital computerized temperature control system maintains ambient temperatures at preselected levels respectively at a plurality of remote locations, each of which may be provided with a digitally operated electronic thermostat of the type described in U.S. Pat. No. 3,942,718. The system includes a real time clock , a keyboard data-entry unit, serial data controllers for sequentially polling each of the thermostats and producing polled temperature data, including a first memory for storing the data corresponding to the desired temperature limits for each thermostat location and a second memory for storing the polled temperature data. A comparator compares the polled temperature data with the desired ambient temperature limit data and accordingly produces overlimit, underlimit and equal limit counts which are stored in another memory. A central processor unit selectively produces heating, cooling, and no-operation signals in accordance with the overlimit, underlimit and equal limit counts.
