UEEEL0008 - Evaluate and modify low voltage heating equipment and controls

For Melbourne campuses

Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:
*applying work health and safety (WHS)/occupational health and safety (OHS) workplace procedures, including identifying hazards, assessing risks and implementing control measures
*checking circuits are isolated in accordance with workplace procedures and regulatory requirements
*determining the operating parameters of existing heating circuits and equipment
*testing the function of a thermostat
*calculating the heat energy in a simple heating process
*testing the operation of an over temperature cut-out of the safety thermostat
*altering existing heating circuits and equipment to comply with specified operating parameters
*selecting heating circuits and equipment to comply with a specified function and operating parameters
*determining the cause of low efficiency in existing heating circuit and equipment
*determining conditions causing an existing heating circuits and equipment to be unsafe
*connecting heating equipment and appliances
*identifying faulty components in heating appliances and controls from test results
*testing heating appliances and controls for serviceability
*ensuring all work complies with relevant Australian Standards and legislation
*completing work and documenting activities
*dealing with unplanned events/situations.

Students will also be expected to demonstrate the following knowledge:
*electrical heating control devices, including:
*methods of manual heat control, automatic heat control
*types and application for common thermostats
