Energy cost allocation system
First Claim
1. A system for allocating energy usage among a plurality of heat exchange terminals each of which comprises heat exchanger means and electrically driven motor means including electrical controls for controlling the operating state of said motor means so that said motor means is operable at at least one discrete operating speed and so that said motor means may be turned off, said system comprising:
- individual monitoring means each coupled to a respective one of said motor means for monitoring the operating state of each of said motor means and for providing a different electrical data signal for each said operating state, each of said monitoring means having associated therewith a unique address code;
central control means;
means providing electrical communication between each of said monitoring means and said control means;
said control means including means for sending signals cyclically polling each of said monitoring means at its unique address code to provide back to said control means said electrical data signals indicating the operating state of each said motor means associated with the polled monitoring means.

Abstract
A system for allocating energy use among a plurality of heat exchange terminals each of which includes a heat exchanger and an electrically driven motor and electrical controls for controlling the operation of the motor. Each heat exchange terminal has associated therewith a uniquely address-coded monitor connected for metering the condition of the motor controls. A central control console periodically polls the monitors at each address code, and in response the polled monitor sends to the interrogating console data indicating the status of the associated motor controls. Memory is provided for accumulating the data so that at the end of a predetermined period the console can compute the proportion of total energy used by each terminal and prepare bills therefrom.
