HVAC & INDOOR ENVIRONMENTAL QUALITY

HVAC Energy Controls

Heating and cooling systems account for the largest share of energy consumption in commercial and institutional buildings. Intelligent HVAC controls reduce that load by optimizing equipment operation — cutting energy use without compromising occupant comfort or system reliability.

Cooling Controls

Cooling Controls

Cooling Controls

Energy economizers automatically optimize compressor cycles based on demand, reducing electricity consumption by 10–30% without equipment replacement. Compatible with air conditioning, compact units, and refrigeration systems.


  • Energy Savings: 10–30% reduction in cooling electricity consumption.
  • Reduced Equipment Wear: Optimized cycles extend compressor service life.
  • Reliability: Consistent, safe operation year-round
  • 15-Year Warranty: Replacement warranty on all cooling control units.

Cooling Controls

Intelligent heating controls adjust burner operation to match actual demand, reducing fuel consumption by 10–30% across warm air systems, hot water heating, and steam heating applications.



  • Fuel Savings: 10–30% reduction in heating fuel consumption
  • Year-Round Efficiency: Demand-based operation without expensive component replacement
  • Reduced Maintenance: Lower wear extends equipment service life
  • 15-Year Warranty: Replacement warranty on all heating control units.



Indoor Air Quality & System Performance

Poor indoor air quality degrades HVAC performance. Particulate buildup on coils, filters, and ductwork reduces airflow efficiency and forces systems to work harder — increasing energy consumption and accelerating equipment wear.
Proactive air quality management reduces HVAC system load, extends equipment service intervals, and maintains consistent airflow performance across the building. Cleaner air means more efficient systems.
Key indoor air quality factors — particulate contamination, biological growth on HVAC components, and volatile organic compounds — are measurable and controllable. Watts Matter designs monitoring and purification systems that address these factors at the source.

UV-C Air Purification

UV-C light at 254nm is the most effective germicidal wavelength for inactivating airborne microorganisms — bacteria, viruses, mold spores, and other biological contaminants. Installed within HVAC ductwork or as standalone units, UV-C systems continuously treat air as it circulates through the building.
Keeping HVAC coils and internal surfaces free of biological growth maintains designed airflow rates and heat transfer efficiency — directly reducing energy consumption and extending service intervals.oor indoor air quality degrades HVAC performance. Particulate buildup on coils, filters, and ductwork reduces airflow efficiency and forces systems to work harder — increasing energy consumption and accelerating equipment wear.

Pathogen Inactivation: Inactivates bacteria, viruses, and mold at the germicidal wavelength


HVAC Integration: Mounts within existing ductwork or air handling units


Standalone Deployment: Far-UV-C units available for open-space applications


Real-Time Monitoring: Optional air quality sensors provide continuous environmental data


Certified Safety: Systems specified to relevant safety and performance standards
