The Controls & Refrigeration Systems Specialist (Building Automation Technician) position primary responsibility for the operation and maintenance of HVAC-R automation systems and other controls systems. Works with the Building Automation System (BAS) and performs calibration, diagnosis, repair, and replacement of Direct Digital Control (DDC) controls and pneumatic, electro-mechanical, and electronic components. Assists plumbers, pump mechanics, electricians, HVAC mechanics, refrigeration technicians, and other trades in the diagnosis, repair, and replacement of their system components.

BAS Operation:
Works with the Metasys Extended Architecture BAS programs and the legacy Metasys PMI functions to analyze and diagnose issues with equipment on the BAS. Uses these functions to respond to customer requests, construction and maintenance needs, equipment failures, power limitations, and planned and unplanned events, including emergencies.

Works directly with customers to troubleshoot and resolve HVAC and other controls issues. Informs customers on how the BAS works, what local control they have over their space, and what limitations there are to their local control.

Monitors spaces and equipment connected to the Building Automation System for trouble, failures, alarms, etc. Initiates responses to resolve these issues.

Under supervision, adjusts set-points and parameters for BAS-connected equipment to improve performance and to respond to changing conditions and customer needs.

Under supervision, programs and adjusts schedules on equipment and alarms in the BAS. Puts overrides on BAS points as needed to overcome functional issues including diagnosing equipment and sensors, understanding the limitations in the software, following the sequence of operations, and ensuring the proper functions of equipment.
