Overview of assessment

A person who demonstrates competency in this unit must be able to coordinate the servicing faultfinding and optimisation of HVACR control systemsThis includes working individually or as part of a team on analysis and optimisation technical tasks

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently

communicate HVACR servicing and faultfinding tasks and requirements to others

identify relevant WHS other regulatory requirements standards and codes

investigate sustainability implications of HVACR control systems

assess HVACR control system and hardware including building management system control systems

use appropriate analysis and simulation software and validation techniques

review thermal loads hardware energy options tariffs consumption benchmarks and comparative tariffs

map and monitor control system IO hardware and energy use

optimise HVACR control system for seasonal and load cycles

measure control system performance

develop optimal control diagram and settings

report and document results

Context of and specific resources for assessment

This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job then a simulated working environment must be used where the range of conditions reflects realistic workplace situations

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team

Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability

Access must be provided to appropriate learning andor assessment support when required Where applicable physical resources should include equipment modified for people with disabilities

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM Metal and Engineering Training Package

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance over time and in a range of workplace relevant contexts together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application

Assessment may be applied under projectrelated conditions real or simulated and require evidence of process

Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency where required

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed
