Powerful and Flexible

Our Vesta is an ideal monitoring and control platform. It has been used successfully in a wide range of applications from home heating to industrial control. Let us help you solve your monitoring or control problems.

Identify and solve problems quickly.

If there is a problem, Vesta provides powerful tools for quick analysis and diagnostics. Detailed datalogs and interactive charts are available from anywhere, including your smartphone.

Make everything work together.

BACnet, 1 wire, Modbus, current loop, RTDs, Insteon, thermistors - Vesta works with all of them. Too often, proprietary subsystems are isolated. Our open-source solution plays well with others.

NEW BENEFIT: Forecast data

Vantage and Pro models can now access a wide range of forecast data including temperature, cloud cover, and insolation. This data can be monitored, datalogged, and used in rules to improve system performance.

NEW PRODUCTS: Pre-configured kits

We now have preconfigured kits available. These kits are ready to go right out of the box, with a Vesta controller and a selection of sensors. Contact us for pricing and delivery information - as always, no annual fees. Available kits include:

  • Professional Diagnostics - packaged in a foam case, ready to gather detailed data to support troubleshooting and analysis.
  • Building Monitor - perfect for keeping tabs on apartments or commercial buildings.
  • Second Home Kit - know what's happening when you're not there and alert appropriate people when there's a problem.

Vesta is the solution

The Vesta can provide direct control of almost any device such as standard Taco, Grundfos, and Honeywell circulators and zone valves. 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.

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.
