What is IoT and how does it work?

IoT is changing HVAC for the Better

Boosting HVAC System Efficiency Using information from a network of building sensors tracking data like temperature, humidity, air speed and air quality, Halo IoT can adjust how your HVAC systems functions to maximize comfort while minimizing energy consumption.


Halo HVAC IoT is far more advanced than a simple thermostat. We deliver data to our cloud (The Halo) for processing, allowing for energy savings and optimal occupant comfort through automation, predictive maintenance, digital ticketing workflows, and remote asset monitoring. With IoT intervention in your HVAC systems, typically you will save 30-60% on your energy costs while increasing occupant comfort. 


By providing access to real-time data, IoT sensors installed on HVAC equipment can improve energy efficiency by monitoring usage trends and even factoring in weather predictions. The result is better-regulated indoor climate control that keeps power consumption to a minimum. 

IoT’s intervention in the low side of the HVAC system enables modulation of variable frequency drives (VFD) & chilled water valves, and scheduling & duty cycling of the AHUs based on the temperature sensor, air quality sensors, humidity, pressure and many other factors. IoT-enabled HVAC automation systems allow you to deliver the maximum occupant comfort with optimal energy consumption. It leads to more sustainable use of resources. 


But before we get there, we need to understand how it works...

Why should IoT be used in HVAC?

Remote IoT monitoring for HVAC systems offers several compelling advantages:


  • Real-time insights: Remote monitoring provides real-time data on HVAC system performance, allowing you to promptly identify any issues or anomalies.
  • Proactive maintenance: With continuous monitoring, potential problems can be detected early, enabling you to schedule preventive maintenance before major breakdowns occur, reducing downtime and costly repairs.
  • Energy efficiency: Remote monitoring allows you to track energy consumption patterns, identify inefficiencies, and implement adjustments to optimize energy usage, resulting in cost savings and a more environmentally friendly operation.
  • Remote control: You can remotely adjust HVAC settings and temperature based on occupancy patterns, weather conditions, or user preferences, ensuring occupants’ comfort and convenience.
  • Predictive analytics: IoT monitoring enables data analysis to predict equipment failures or performance degradation, allowing you to take proactive measures to avoid disruptions and extend the lifespan of HVAC components.
  • Cost-effectiveness: By detecting issues early and optimizing energy consumption, IoT monitoring can lead to reduced maintenance costs and lower utility bills over time.
  • Improved safety and compliance: Monitoring sensors can detect unsafe conditions or deviations from regulatory standards, ensuring a safer environment and compliances.
  • Scalability and centralization: For larger buildings or multi-site facilities, remote IoT monitoring centralizes HVAC management, simplifying maintenance tasks and streamlining operations.

Overall, remote IoT monitoring empowers facility managers to make data-driven decisions, optimize HVAC system performance, enhance energy efficiency, and increase the overall reliability and lifespan of the equipment.

  11. Cost Savings: Energy-efficient operations and predictive maintenance lead to substantial long-term cost savings.
  12. Regulatory Compliance: Monitoring systems can help ensure compliance with HVAC-related regulations and standards.

Applications of IoT in HVAC 

Automation of HVAC operations


Halo HVAC IoT is capable of automating HVAC operations. There are no limitations to the scalable application of IoT. 


Our sensors in an IoT-powered HVAC system collect data from various data points, including airflow, ambient temperatures, humidity, air quality, energy use; chiller’s return & leaving water temperature amongst more applications. The data is securely sent to the Halo cloud through a gateway. The Halo gateway enables automation or manual control of the HVAC system. 


Your HVAC system data is processed and delivered back to devices such as VFDs, Valve cards, Relays retrofitted at several points of an existing HVAC system. These devices then apply these instructions to modulate various HVAC system components like the chilled water valve, secondary pump, condenser pump, etc. While reading it might seem like a long & complex process but it all happens within seconds without any manual intervention.

HVAC Monitoring

Halo HVAC sensors portal is a cloud based mobile internet platform and central hub for managing Halo products. 


All data is secured on dedicated servers operating Microsoft SQL Server. This online user interface is where all your device settings can be arranged, supervised, and modified to reflect your unique environment. You can access your sensors data on an internet browser simply by typing www.halohvac.co.uk/dashboard into the address bar. 


In addition, you can also download the Halo App to your smartphone or tablet. Start with the basic version or upgrade to Halo Premiere to enjoy the full features your Halo experience can offer.
