Vermont Energy Control Systems

Practical monitoring and control for the real world

Home

Vermont Energy Control Systems produces the Vesta family of controllers, sensors, and related equipment. This open-source platform gives you the tools to get the most out of your system. Applications range from complex heating systems to thermal management to greenhouses to humidity monitoring and control.

Our goal is to help you get the most out your system - new or old, simple or complex. Our Open Source solution puts you in control:

  • Monitor temperature, pressure, electrical current, humidity and more - quickly, easily, and accurately from anywhere. See what's happening at any time.
  • Log your data - every input, every output, every minute. Up to 12 months of data can be logged internally. Data can also be logged to a remote database if desired.
  • Control your environment. Perform direct control of relays, lights, pumps, and fans using simple rules.
  • Analyze system performance. See and understand system behavior.

Vesta is the solution

The Vesta can provide direct control of almost any device from standard Taco, Grundfos, and Honeywell circulators and zone valves to industrial controls. It performs all the functions of a zone controller, differential controller, outdoor reset controller, and setpoint controller in a single device. Unlike the individual stand-alone devices that it replaces, all functions work seamlessly together. Every input, output, and control action is logged to support analysis and fine-tuning.
