Thermostats are incapable of achieving maximum efficiency for the cycles in air conditioning, heat pump and refrigeration systems. The Auditor on Board™ resolves this shortcoming.

At start up, a cooling system produces a large temperature drop using little energy.

As the temperature drops closer and closer to its lowest set point, the system compressor uses more and more energy to produce that temperature drop.

The Auditor on Board™ is installed between the primary controller (like a thermostat) and the compressor, allowing it to intercept signals from one to the other.

The Auditor on Board™ then determines when and for how long a compressor will run, helping the compressor operating cycle to run in its most efficient state.

By helping the compressor run in this more efficient state, the Auditor on Board™ reduces the total run time of the compressor. This reduces the total electrical consumption of the compressor.

Auditor on Board™ can save an average of 15% (kWh) usage and 10% (kW) peak demand on compressor operation.
