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 of 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.

Typical Applications

Multi-source heating systems with wood gasification boilers and heat storage.
Integration of solar hot water with storage and backup heat sources.
Industrial controls.
Multi-room heat and air conditioning setback.
Complex heat pump systems.

High-Humidity Monitoring

Vermont Energy Control Systems is working to provide a new humidity sensor developed at the University of Vermont, optimal for high-humidity environments where conventional sensors will fail. Applications include the processing and aging of specialty foods and long-term storage of root vegetables and other crops requiring high humidity.

New Case Study: Consolidated Dashboard

This case study describes the use of a Vesta controller to collect and display live data from a wide variety of other systems. This case study falls at the ‘very complicated’ end of the spectrum, but it shows the power of the open source tools provided with the Vesta controllers.

Use NOAA Weather Forecast Data

Did you know that Vesta system can receive and use NOAA weather forecast data? This means you can set rules for your system based on predicted temperature, cloud cover, and more.
