Bayer Controls delivers controls commissioning for new and upgraded HVAC installations, ensuring systems are correctly configured, tested, and verified before handover. Our work covers controller setup, addressing and network configuration, functional testing, and performance verification across VRF systems, central controllers, and integrated plant, with particular strength in Mitsubishi Electric equipment. By methodically commissioning each system to manufacturer and Australian Standards requirements, we ensure installations operate as designed from day one and provide a documented basis for ongoing operation and maintenance.

Bayer Controls delivers planned and reactive HVAC maintenance for commercial buildings, keeping heating, ventilation, and air conditioning systems operating reliably and efficiently. Our maintenance covers scheduled servicing, performance verification, and fault rectification across VRF systems, central controllers, and associated plant, with particular strength in Mitsubishi Electric equipment. By identifying developing issues early and maintaining systems to manufacturer and Australian Standards requirements, we help clients minimise unplanned downtime, extend equipment life, and maintain consistent occupant comfort.

Bayer Controls provides asset management services that give building owners and facility managers clear visibility over the condition, performance, and lifecycle of their HVAC and controls assets. We maintain accurate asset registers, track servicing history, and assess equipment condition to support informed decisions around repair, replacement, and capital planning. With this approach, clients can forecast expenditure with confidence, prioritise works based on actual system condition, and maximise the return on their building services investment over the long term.

Bayer Controls produces detailed lifecycle reporting that documents the age, condition, and expected service life of a building's HVAC and controls assets. Each report draws on inspection findings and servicing history to identify equipment approaching end of life, flag emerging risks, and recommend a prioritised schedule of works. This gives owners and facility managers a clear, evidence-based basis for capital planning and budgeting, ensuring replacement and upgrade decisions are made proactively rather than in response to failure.

Bayer Controls provides building management system services built on the Tridium Niagara platform, covering integration, configuration, and commissioning of HVAC controls into a building's wider BMS. Working in Niagara N4, we integrate Mitsubishi Electric VRF systems, central controllers, and third-party plant via BACnet, ensuring equipment is correctly mapped, monitored, and controllable from a single platform. Whether integrating new equipment or resolving communication issues on an existing installation, we deliver reliable interoperability between controls and the building management system.

Bayer Controls provides power apportioning services using Mitsubishi Electric central controllers to distribute total energy consumption across individual indoor units for accurate tenant billing. We configure and commission the apportioning function on AE-200/AE-C400 and EW-50/EW-C50 controllers, ensuring energy usage is allocated according to each unit's actual operation. This gives building owners and managers a reliable basis for recovering running costs from tenants, with transparent data drawn directly from the system.

Bayer Controls offers offsite monitoring through secure remote access established directly to a site's central controller. This connection allows us to review maintenance tool data and fault logs remotely, providing visibility over system performance and operating status without the need for an on-site visit. By monitoring equipment condition and interrogating fault history remotely, we can diagnose issues quickly, respond to developing faults before they escalate, and reduce both response times and unnecessary call-outs.

Bayer Controls services air-cooled VRF systems, which use a single refrigerant circuit to provide simultaneous heating and cooling across multiple indoor units, rejecting heat directly to outside air. We commission, maintain, and fault-diagnose these systems across a range of manufacturers, with particular expertise in Mitsubishi Electric City Multi equipment. From outdoor unit performance to indoor unit operation and refrigerant circuit diagnostics, we keep air-cooled VRF systems running efficiently and reliably.

Bayer Controls services water-cooled VRF systems, including the Mitsubishi Electric City Multi PQRY range, which reject heat to a water loop rather than directly to outside air, making them well suited to high-rise and space-constrained buildings. We commission, maintain, and fault-diagnose these systems, covering outdoor unit operation, water loop interface, indoor unit performance, and refrigerant circuit diagnostics. With deep familiarity with the PQRY platform, we keep water-cooled VRF systems operating efficiently and reliably.

Bayer Controls services Mitsubishi Electric Hybrid VRF systems, which combine a refrigerant circuit between the outdoor unit and Hybrid BC controller with a water circuit to the indoor units, delivering simultaneous heating and cooling without refrigerant in occupied spaces. We commission, maintain, and fault-diagnose these systems, covering outdoor unit operation, HBC performance, water circuit interface, and indoor unit control. With established expertise in the HVRF platform, we keep these systems operating efficiently and reliably.

Bayer Controls services Mitsubishi Electric PAC-AH air handling unit connection kits, which allow a direct-expansion coil within an air handling unit to be driven by City Multi VRF outdoor units. We commission, maintain, and fault-diagnose these systems, covering the PAC-AH controller interface, coil and expansion valve control, sensor configuration, and integration with the wider VRF network. With established familiarity with the PAC-AH platform, we ensure DX air handling units operate reliably and in step with the connected system.
