General Information
Expert Training
This catalog presents complete descriptions and schedules for our current offering of HVAC and controls courses. These courses are designed to increase technician competence and build confidence when servicing newer systems and controls.
Course instructors have strong HVAC and controls service backgrounds and extensive teaching experience. They also have ready access to Trane's highly knowledgeable product, service and systems engineers and to Trane's extensive technical reference library. A controlled laboratory environment, complete with fully operational Trane HVAC systems, provides the ideal setting for the hands-on approach used in Trane service courses.
The cost of professional training always pays you back - sometimes within weeks! Well-trained technicians, with a good understanding of controls, refrigeration and airside systems, using correct diagnostic methods, are more likely to minimize service costs by efficiently identifying and correcting problems, and not wasting time and materials with trial and error methods.
Enrollment Policy
To get the most effective training, carefully match your students with the appropriate courses by reviewing the course content and objectives with them. All courses are offered on a first registered first attend basis. If the class you prefer is filled, we can hold standby space for the date you prefer (in case there's a cancellation) and register you for the same course offered at a later date.
If you register in advance, we will send you a confirmation letter about a month before the scheduled course starting date to verify your enrollment. Check it carefully and contact us immediately if you find an error in it. If you haven't received confirmation within two weeks of the course start date, you may not be properly registered for the course. In this case, contact us immediately! If you register late (within 2 weeks of the course date), we will FAX your confirmation letter to you at that time.

Course Benefits
This course is intended to improve a technician's ability and confidence when electrically troubleshooting commercial HVAC equipment. The course will broaden the technician's capabilities to troubleshoot controls and other electrical circuits by teaching an understanding of practical electrical theory as applied to the products and components found in HVAC. The information and skills learned should greatly decrease service diagnosis time and take the guesswork out of isolating problems found in single-, and three-phase air conditioning and heating products.

Course Benefits
This course will benefit technicians who service the unitary control systems of Trane commercial products. It assumes the student is trained and has experience servicing the mechanical and refrigeration portions of the products and systems covered. Coverage concentrates on electronic and micro-electronic controls used by Trane for commercial unitary products and systems. This course does not cover centrifugal chiller controls. Major emphasis is placed on master energy controls (MEC) such as the W7100, IntelliPakTM, Voyager® and Precedent-Reliatel unitary control processors. This course will provide general coverage of control system theory to help students "visualize" overall control strategies. Each MEC is covered in the classroom through lecture and discussion. Then each student is afforded the opportunity to operate, check out and troubleshoot the MECs on operating equipment in the training laboratory. Students will also be exposed to some Integrated ComfortTM Systems (ICS) controls such as Tracer Integration Modules (TIM) and TCM. These ICS controls

are covered from the HVAC equipment standpoint in order to teach interfacing and troubleshooting concepts.
Specific Course Objectives
· Become proficient at troubleshooting the W7100, Voyager, IntelliPak and Precedent-Reliatel UCPs. · Understand control system logic and system functional limitations. · Learn operation, checkout and troubleshooting techniques. · Build on a strong foundation of control concepts and fundamentals for more precise and logical troubleshooting techniques. · Develop diagnostic skills to become more adept at determining control system problems. · Troubleshoot commercial air condition ing controls used on older Trane or competitive equipment. · Develop skills to isolate ICS control problems from equipment control problems.
Target Audience
This course provides the most benefit to service technicians who need broader control familiarity and BAS technicians who lack HVAC experience. It is wellsuited for "systems oriented" technicians who want to use a diagnostic approach rather than parts changing methods. It is intended for A/C technicians who want to discover how controls and control systems really work. Industrial facility technicians should attend only if the specific controls covered are used in their facility.
Prerequisites
Students should be versed in electric and electronic control terminology. They should have a firm foundation of electrical wiring schematics and troubleshooting skills as well as general HVAC systems understanding of how and why individual controls interface with HVAC equipment. HVAC Electrical Troubleshooting is an excellent foundation course for this one.

Course Benefits
This course will benefit technicians who regularly work with commercial or industrial type HVAC units which utilize different starting methods. It is assumed and required the student has a good working knowledge of electricity and is responsible with maintaining good safety procedures. Trane has announced the addition of a unit mounted "medium voltage (2200/4160)" starter. With starter technology growing at a rapid pace, and with the addition of the 2200/4160 unit mounted starter, we feel the time has come to offer this training. Safety will be paramount and safety procedures will be discussed pertaining to every starter discussed. The material presented will mainly cover the starting methods used by Trane, however this coverage can be easily applied to manufacturers who use other starters.
Coverage will include motor basics, SAFETY with all starters, and a strong emphasis will be placed on safety concerning medium voltage starters. This course will also cover wye-delta starters; frequency drives; solid state starters; across the line starts as well as discussions of why starting methods are required.

Course Outline
troubleshooting, operation / maintenance of starter types used with chiller systems. Usually advanced technicians are tasked with starter work, however this class is a "ground level" course, well-suited to anyone with a strong electrical background. We will also be discussing medium voltage starters which are now unit-mounted on some Trane chillers at the factory. This poses a scenario not directly associated with the lower voltage starters. Heavy safety emphasis will be apparent during the entire course, however special attention will be given to medium voltage starters.
These starters are used in many applications other than HVAC. Anyone wanting a good understanding of starters (provided they have a strong electrical background) are welcome to attend.
Prerequisites A strong understanding of electrical principles is mandatory. Training in control theory and the ability to understand wiring schematics is also important. HVAC Electrical Troubleshooting is an excellent foundation course to attend if the above requirements are not met.

Course Benefits This course will broaden any technician's level of service and overhaul expertise. It will help them gain confidence and experience in system start-up, maintenance, repair and major overhaul of water-cooled CenTraVac® chillers. The course provides learning situations not otherwise available or that may take months or even years of on-the-job exposure to encounter.
This course lays a substantial foundation for the technician's continued professional growth and provides familiarity with other centrifugal chiller products. This is a mechanical service course only. Controls course attendance is required for complete CenTraVac chiller service coverage.
Notice: The Trane Company reserves the right to reject any training course application.
