Job description

Position Summary

This role focuses on maximizing the application of CAREL's control and cooling solutions in commercial HVAC environments by developing, communicating, and implementing market best practices for medium‑to‑large equipment installations with OEMs and end‑users. The Application Specialist guides OEM applications and commissioning for commercial HVAC equipment including Dedicated Outdoor Air Systems (DOAS), rooftop units (RTUs), commercial heat pumps, variable refrigerant flow (VRF) systems, and air handling units (AHUs), leveraging CAREL's full portfolio of controllers, drives, dampers, heat exchangers, valves, and supervisory solutions.

Role Overview

The Application Specialist proactively leads initiatives to apply efficient CAREL control strategies for commercial HVAC systems, supports OEMs and building owners in early implementation phases, and serves as the CAREL commercial HVAC control expert. The role delivers technical training internally and externally.

Key Equipment Platforms

• Dedicated Outdoor Air Systems (DOAS) – energy recovery ventilators, dehumidification units, and fresh air handling for commercial and institutional buildings
• Commercial Rooftop Units (RTUs) – packaged and split rooftop systems serving retail, office, and industrial light‑commercial facilities
• Commercial Heat Pumps – air‑to‑water, water‑to‑water, and geothermal heat pump systems including VRF controls for multi‑zone commercial applications
• Air Handling Units (AHUs) and Fan Coil Units (FCUs) – terminal and central station air handlers for commercial, healthcare, and hospitality environments
• Chillers and Chilled Water Systems – commercial chilled water plant controls, primary‑secondary pumping, and sequencing

Essential Duties & Responsibilities

• Actively support design and implementation of complete CAREL HVAC control solutions with OEMs in commercial markets, focusing on energy efficiency, dehumidification performance, ventilation compliance (ASHRAE 62.1), demand‑controlled ventilation, and integration with BMS/BAS platforms.
• Guide OEM selection and configuration of CAREL controllers, electronic expansion valves, variable speed drives, and supervisory systems for DOAS, RTU, heat pump, and AHU applications.
• Support commissioning, startup, and troubleshooting of commercial CAREL‑controlled equipment at OEM facilities and customer job sites, focusing on refrigerant circuit optimization, economizer logic, heat recovery wheel controls, and humidity management.
• Provide technical expertise on integration of CAREL systems with building automation systems via BACnet, Modbus, and LonWorks protocols in commercial building environments.
• Participate in product strategy and development discussions with CAREL's global engineering teams based on commercial application needs.
• Develop and deliver technical training programs, application notes, configuration guides, and commissioning documentation for OEM partners, mechanical engineers, and building contractors.
• Partner proactively with OEM engineering teams to plan, design, and solve systemic control issues before units ship to commercial job sites.
• Collaborate with sales, engineering, marketing, and product management to develop commercial application solutions responsive to market needs.
• Communicate status and actions needed for problem resolution internally and externally; elevate urgent issues related to commercial HVAC control failures or opportunities.
• Identify 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)

Apply CAREL control solutions to DOAS equipment requiring precise outdoor air conditioning, energy recovery, and dehumidification. Key competencies include demand‑controlled ventilation, ASHRAE 62.1 compliance, CO₂‑based reset strategies, and integration of CAREL humidity sensors and controllers.

Commercial Rooftop Units (RTUs)

Configure CAREL controllers and drives for packaged commercial rooftop equipment ranging from small tonnage split systems to large built‑up rooftop platforms. Focus on compressor staging, variable speed control, economizer damper control sequences, heat exchanger management, and refrigerant circuit protection.

Commercial Heat Pumps – Air‑to‑Water, Water‑to‑Water, and VRF

Support OEMs developing commercial heat pump products using CAREL controls, including reversing cycle management, defrost logic, refrigerant charge optimization, COP monitoring, and integration with hydronic distribution systems. Geothermal and ground‑source heat pump controls are also within scope.

Air Handling Units, Fan Coil Units, and Central Station Equipment

Guide OEMs in applying CAREL's full controls ecosystem to commercial AHUs and central station equipment, covering VAV controls, static pressure reset, supply air temperature reset, heat recovery, and humidification.

CAREL Product Integration and Supervisory Systems

Provide guidance on building integrated commercial HVAC solutions using CAREL controllers, electronic expansion valves, supervisory software, and variable speed drives, ensuring correct configuration, programming, and commissioning.

Energy Efficiency and Building Integration

Apply knowledge of ASHRAE 90.1, ENERGY STAR, demand response programs, and time‑of‑use energy optimization. Integrate CAREL supervisory platforms with building management systems via open protocols and cloud‑based energy monitoring solutions.

Reporting Responsibilities

This position reports directly to the Sr. Application Manager within CAREL's matrix organization model and collaborates across sales, engineering, product management, and global marketing solutions teams.

Competencies

Commercial HVAC Systems Expertise

Demonstrated ability to configure, commission, and troubleshoot medium‑to‑large commercial HVAC equipment, with strong preference for hands‑on experience with CAREL controller platforms, electronic expansion valves, and variable speed drives.

Problem Solving

Identify and resolve technical problems in a timely manner; skilled at gathering and analyzing system data from CAREL controllers.
