This unit involves the skills and knowledge required to audit heating, ventilation and air conditioning/refrigeration (HVAC/R) control systems for compliance with regulations and standards.

It includes working safely, setting up and conducting evaluation measurements, evaluating performance from measured parameters, and documenting results and recommending any resulting corrective actions.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least one occasion and include:

interpreting compliance documents

setting up and conducting appropriate examinations and tests

identifying non-compliance defects

reporting examination and test results and non-compliance issues clearly and accurately

applying relevant work health and safety (WHS)/occupational health and safety (WHS/OHS) requirements, including using risk control measures

auditing heating, ventilation and air conditioning/refrigeration (HVAC/R) control systems for compliance with regulations and standards

completing auditing work and documenting results

dealing with unplanned situations

preparing to audit HVAC/R control systems.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of:

HVAC/R control system audits, safe working practices and relevant standards, codes and regulations, including:

review of HVAC/R system components

performance requirements of control applications from available system specifications and design briefs

descriptions of operation

measurements and recordings of system performance, as required to confirm plant control compliance with desired conditions

comparison of system specifications, control strategies, design briefs and recorded test results with current HVAC/R energy management principles to establish the economy of operation of HVAC/R plant

preparation a detailed report outlining the results of investigation and stating suggested control system adjustments, alterations and modifications to improve the performance of the plant

relevant job safety assessments or risk mitigation processes

relevant manufacturer specifications

relevant systems for compliance with regulations and relevant industry standards

relevant WHS/OHS legislated requirements

relevant workplace documentation

relevant workplace policies and procedures.

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or simulations

relevant and appropriate materials, tools, facilities and equipment currently used in industry

applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.
