• Collaborates with sales, engineering, marketing, and product management to develop commercial application solutions responsive to market needs.

• Communicates in a timely manner the status and actions needed for problem resolution internally and externally; elevates urgent issues related to commercial HVAC control failures or opportunities.

• Identifies best CAREL controller practices from the OEM and contractor perspective, developing application standards that address common commercial HVAC requirements.

Technical Focus Areas Dedicated Outdoor Air Systems (DOAS) The specialist will apply CAREL control solutions to DOAS equipment requiring precise outdoor air conditioning, energy recovery, and dehumidification. This includes control of refrigerant-based cooling and heating coils, energy recovery wheels, heat pipes, and runaround coils. Key competencies include demand-controlled ventilation (DCV) logic, ASHRAE 62.1 compliance, CO₂-based reset strategies, and integration of CAREL humidity sensors and controllers to maintain neutral or slightly positive supply air dewpoint. The specialist will configure and optimize CAREL controls for refrigerant circuit management

Commercial Rooftop Units (RTUs) Expertise is required in configuring CAREL controllers and drives for packaged commercial rooftop equipment ranging from small tonnage split systems to large built-up rooftop platforms. The specialist will work with OEM engineering teams on compressor staging and variable speed control using CAREL inverters, economizer damper control sequences, heat exchanger management, and refrigerant circuit protection. Focus areas include demand response integration, power metering, and configuration of CAREL supervisory tools for fleet monitoring of multi-site RTU installations across retail and commercial portfolios.

Commercial Heat Pumps – Air-to-Water, Water-to-Water, and VRF The specialist will support OEMs developing commercial heat pump products using CAREL controls. This encompasses reversing cycle management, defrost logic, refrigerant charge optimization with CAREL electronic expansion valves (ExV), COP monitoring, and integration with hydronic distribution systems..
