Solar Design Seminar Series

This three-part series will take you through the Viessmann Solar Design Guide.

After participating, you will leave with the following information:

  • What solar thermal technology is
  • What applications are best suited for Viessmann solar collectors
  • How to calculate the number of collectors for a project
  • How the Viessmann solar thermal system is installed
  • How to size the components of a solar thermal system (pipe, circulators, expansion tanks, etc)
  • If heat dissipation is required
  • How to start up the system once it has been installed

Expansion Control

Often the expansion tank is one of the items that doesn't get much thought when it comes to hydronic system design.

In this presentation, we will dig deeper into the expansion tank and address these questions:

  • Why is the expansion tank required?
  • What is the relationship between the expansion tank, fill valve and safety valve?
  • Is an expansion tank the same as a compression tank?
  • What is the critical sizing for an expansion tank?
  • Where in the hydronic system does the expansion tank belong?

Learning objectives:

  • Explain why an expansion tank is required
  • Contrast the design and functionality of an expansion tank and a compression tank
  • Describe how an expansion tank is sized
  • Describe the best location for an expansion tank

Building a Foundation: Vitocrossal 300 CU3A Seminar Series

Part 1:  Product Overview

This three-part series is for those interested in learning more about the Vitocrossal 300 CU3A boiler. The first class will take you through a limited overview of all aspects of installation – venting, piping, gas supply, Lambda Pro, wiring, programming, and the start-up wizard.

Learning objectives:

  • Describe the primary difference between a CU3A boiler compared to typical wall-hung condensing boilers
  • Identify common applications for a Vitocrossal 300 CU3A boiler
  • List four features of the Vitocrossal 300 CU3A and their benefits
  • Identify the most common method of piping for the CU3A boiler

Building a Foundation: Vitocrossal 300 CU3A Seminar Series

Part 2:  Wiring & Control Interface / Basic Programming

This three-part series is for those interested in learning more about the Vitocrossal 300 CU3A boiler. The second seminar will expand on the wiring & control interface, and the basic programming which is critical to understand for start-up procedures.

Learning objectives:

  • Identify the line voltage, low voltage and sensor connections
  • Describe the quality of the boiler control that sets Viessmann apart from others
  • Explain the two methods to wire the low water cut-off
  • Identify the HO1B control buttons and the home screen display symbols
  • Explain the importance of correct time and date in the control
  • Describe the two choices of boiler temperature control when using the start-up wizard
  • Describe the process of selecting the proper heating curve and how to adjust it for different emitters

Building a Foundation: Vitocrossal 300 CU3A Seminar Series

Part 3:  Service / Maintenance

This three-part series is for those interested in learning more about the Vitocrossal 300 CU3A boiler. The third seminar will be an overview of service and maintenance, which will take you through what tools are needed and the steps to follow when performing the annual maintenance on this boiler.

Learning objectives:

  • Describe how to remove the burner assembly and the proper cleaning techniques
  • List the recommended chemicals and tools needed to clean the heat exchanger
  • Describe two maintenance tips to avoid condensate backup
