Basic Electricity & Hydronics

Basic Electricity and Control Theory - Bruce Marshall

Perfect for:

• Service technicians and equipment installers looking for a good overview of HVAC controls
• Technicians in need of additional NORA CEU’s

Learn about:

• Zone valves & zone controls
• Proper control wiring
• Pump relay controls
• Outdoor reset controls

This seminar is about basic electricity and low voltage controls. If you are intimidated by electricity or just don’t get it, this is for you. We will explain series and parallel circuitry. Ohm’s Law and the relationship between volts, amps, watts and ohms will be taught. Various electrical components such as transformers, relays, zone valves, and multiple controls will be thoroughly explained. You will learn useful information such as compatibility between Honeywell and Taco controls. Outdoor reset and priority zoning will also be discussed. The attendee will gain an understanding of basic electricity and controls used in the heating industry. This course will be of value from the beginner to the experienced technician.
Approved for 3 NORA CEU’s.

Basic Hydronics

Perfect for:

• The new contractor looking to gain more knowledge on the operation of a modern
• hydronic system
• Experienced contractors looking to brush up on the basics and keep abreast of modern technology developments

Learn about:

• Heat transfer principles
• Various piping techniques
• All hydronic heating system components
• Proper boiler pumping

This seminar will explain how heat is transferred from water to air. Convection, conduction, and radiant concepts will be covered. An explanation of the components of a heating system and their relationship to each other will be given. The course covers boilers, pressure reducing valves, relief valves, expansion and compression tanks, air scoops, Vortech air separators, flow checks, integral flow checks, pumps and circulators, zone valves, and Venturi tees. The relationship between BTU, GPH, and Delta T will be thoroughly explained and some “rules of thumb” explained. The concept of “pumping away” and why it should be utilized will be explained in depth. Near boiler piping including by-pass location will be studied. Proper piping techniques will also be covered; series loop systems, 2 pipe direct return, 2 pipe reverse return, mono-flo, and primary / secondary piping.
Approved for 4 NORA CEU’s.
