Virtual Comfort College Course Topics:

  • HeatPumPro Zone Weighting
    • This course will focus on how the Arzel HeatPumPro controls the W2/Y2 outputs to match the system capacity to the size of the zones, and how the zone weighting can help eliminate the need for a bypass damper, as well as reduce energy consumption on the HVAC equipment.
    • Why attend? Gain a better working knowledge on using 2 stage equipment or using ECM upgrade motors in place of PSC motors to reduce energy consumption, and maximize comfort for your customer.
  • Forced Air and Hydronics
    • This course will address installing a forced-air system with a hydronic system and explain how they can run together, providing additional stages of heating for better comfort.
    • Why attend? Learn and understand how the controls on the boiler and forced air system can work together from the zoning control to enhance the effectiveness of your customers’ HVAC system.
  • Zone Sizing and System Adjustments
    • The course will explain how to better determine the number of zones a building needs and how to avoid micro zoning that could potentially damage the HVAC equipment.
    • Why attend? Communicate better with your customers and council against micro zoning that can damage the HVAC equipment, and learn how to best optimize the system in the event a small zone is desired by their customer.
  • Bypass Theory
    • This course will cover the purpose of bypass air, the methods of controlling bypass air, how bypass air has been improperly used, and how bypass is properly calculated bypass to minimize or negate the negative effects commonly associated with using a pressure relief damper.
    • Why attend? Be able to confidently determine if a bypass is needed in a zoning application, and how to size it properly to limit or negate the negative effects bypass air can have on an HVAC system.
  • Arzel CoolMizer
    • The course will concentrate on the need for fresh air and economizers in more energy-efficient buildings, plus the requirements or needs created by the thermal envelope of a tight building structure, and how the Arzel CoolMizer was designed to meet these specific applications.
    • Why attend? Discover our easy economizer solution for split system HVAC units and understand how it belongs into the fast-growing market for green construction and better IAQ.
  • Multistage Equipment and Zoning
    • This course will describe how multi-stage equipment from 2 stage to modulating and inverting equipment is affecting the home zoning performance, and how the two technologies are operating together to enhance comfort and reduce energy consumption.
    • Why attend? Get more prepared to discuss the advantages of installing multi-stage equipment with zoning together for the greatest in comfort and energy savings for your customer.
  • Effective low voltage testing
    • The course will cover the basics of HVAC controls, leading to more advanced applications where technicians often seem to stumble and look for guidance.
    • Why attend? Gain a better grip on how HVAC controls work to more effectively diagnose faults as well as create more robust solutions for your customer.
  • Airflow Dynamics and Bypass Theory
    • This course will focus on what the appropriate static pressure should be in an HVAC System, with and without zoning, as well as how to best control the static pressure if it becomes too high.
    • Why attend? Get away from the idea of “it’s good enough” and push the HVAC equipment to provide the maximum performance and comfort for your customers.
  • Proper Zoning System Design
    • Section 1: Introduction and definition of the difference between TSP and ESP, as. well as how and where to test for the TSP and ESP.
    • Section 2: Common design failures when designing the ductwork for zoning applications, and how to avoid future failures of such kind.
    • Section 3: Homeowner input: What facts are needed from the customer to effectively correct their home’s trouble spots and comfort issues?
    • Why attend? Clear up common misconceptions when installing zoning to a forced-air furnace, understand how it affects the operation of the equipment, and confidently design the zoning system to maximize comfort for your customers.
  • Arzel HeatPumPro Setup and Troubleshooting
    • Section 1: A detailed description of the HeatPumPro set-up to answer technicians’ questions and address the most common set-up errors that can create undesirable operation.
    • Section 2: Basic electrical troubleshooting discussing how to properly use a multimeter to diagnose HVAC equipment IE: thermostats, zoning panel, furnace inputs.
    • Section 3: Arzel specific troubleshooting, learn how to properly use your manometer to diagnose damper operation.
    • Why attend? Become more familiar with how the HeatPumPro can optimize comfort and save your customers money on energy costs by effectively controlling the HVAC equipment.
