Congratulations on your purchase, and welcome to the community of Vesta owners. This page is a collection of resources to help you make the most of your system.


How-To Documents

There are a number of short documents that show how to accomplish specific tasks related to the Vesta itself and the network it's connected to.

  • Get Vesta IP Address. In order to connect to your Vesta from remote locations, you need to know its external IP address. This page will give you the IP address based on your serial number. The serial number is on the right side panel of your Vesta.
  • Obtain Network Information. As a network device, the Vesta has to be configured for the network it will be on. Normally that's done at the factory prior to delivery. This page describes how to obtain the information that we need to set up the Vesta. If your network configuration changes (perhaps due to a new router, for instance) this information may be needed to reconfigure the Vesta.
  • Enable External Access. This is the ability to access your Vesta from 'outside' - when you're not in the same building. External access is not necessary, but most users want to see and/or control their system from their smart phones while on the road. This document covers the network configuration that's required to make external access possible.
  • Troubleshoot Network Issues. Sometimes computer networks don't work the way they should. If you're having difficulty accessing your Vesta, this document can help.
  • Change Network Settings. The Vesta is usually set up before leaving the factory, but if it's moved to a different network (or if the network configuration changes) the Vesta's network settings will have to be changed to match. This document describes the process.


Tutorials cover topics that don't relate directly to the Vesta itself, but which may be relevant to Vesta users.

  • Understand and Use Relays. Relays are a key electrical device in most systems. This document covers theory, terminology, and terminal numbering standards.
  • Heat Storage. Heat storage is becoming a more common practice, and there are many approaches. This document provides a quick introduction.
  • Thermostat Wiring. What goes on inside a thermostat? What are all those wires? This document answers these questions.

Application Notes

These are brief documents that show how to use Vesta hardware and software to perform typical system functions. Each example includes a schematic, wiring, and Vesta setup as needed.

  • Control a Circulator. This shows using a Vesta relay to turn a circulator pump on and off based on a system temperature. This technique applies to control of almost any on/off device.
  • Monitor a Pump. This example shows monitoring that status of a device (a pump in this case) that's not controlled by the Vesta. Rules are shown that will send an alarm message if there's a problem.
  • Failsafe Control. In this example, the Vesta is set up to take control of a device (a blower) in such a way that it can be switched back to the original controller at any time, and automatically if the Vesta fails.
