Comparing Intesis Multi-System Adapter and CoolMasterNet: Pioneers in HVAC Integration Technology

The contemporary advancements in Heating, Ventilation, and Air Conditioning (HVAC) technology deliver the integration of sophisticated HVAC systems with Building Management Systems (BMS). Notably, two state-of-the-art products, CoolAutomation’s CoolMasterNet and Intesis’s Multi-System Adapter, stand out in the industry. This article undertakes a comprehensive comparison of these HVAC integration systems, evaluating their key features, compatibility, installation processes, and overall value proposition.


CoolMasterNet, presented by CoolAutomation, is an advanced HVAC gateway solution that boasts of managing multiple HVAC units simultaneously1. It is available in two versions: CoolMaster and CoolMasterPRO, which offer versatility in residential automation and Building Management System (BMS) integration1. CoolMasterNet’s key feature lies in its capability to simultaneously connect to diverse types of HVAC systems and allows concurrent control by multiple Modbus masters1.

Intesis’s Multi-System Adapter is a multi-protocol interface designed to control various air conditioning systems from a multitude of manufacturers. Provided in small and medium versions, these adapters support a wide range of HVAC systems and indoor units. A distinguishing feature of Intesis adapters is the built-in support for multiple protocols such as KNX, BACnet/IP Client, BACnet MS/TP Master, Modbus RTU/TCP, and ASCII.


CoolMasterNet shines in its vast compatibility range, including major HVAC systems by Daikin, Mitsubishi, Toshiba, and Fujitsu. It also interfaces seamlessly with home automation systems like Crestron, Control4, and Savant. However, it’s important to note that CoolMasterNet necessitates an external dongle for KNX support, implying an additional cost1.

The Intesis Multi-System Adapter extends the compatibility spectrum of CoolMasterNet. The small version is compatible with Hisense, Hitachi, Midea, Mitsubishi Electric, Panasonic, and Samsung HVAC systems. The medium version increases the capacity, handling up to 100 groups for Mitsubishi Electric City Multi systems. The built-in support for multiple protocols further distinguishes Intesis from CoolMasterNet.

Installation and Configuration

Both systems offer user-friendly and flexible installation processes. CoolMasterNet impresses with its plug-and-play connectivity and provides both cloud-based and direct connection control options.

Intesis, although it requires a slightly higher level of expertise in protocol communication for setup, offers a robust solution. Its device discovery functionality simplifies the setup, reducing commissioning time.

Overall Value

The comparison of CoolMasterNet and the Intesis Multi-System Adapter largely depends on specific project requirements. CoolMasterNet holds an advantage for multi-unit installations with a variety of HVAC system types, although it requires an additional dongle for KNX support.

On the other hand, Intesis stands out with its multi-protocol support, wide HVAC compatibility, and built-in KNX support. Its additional adapters for different brands increase its flexibility, making it an exceptional choice for intricate building automation projects.

To conclude, both CoolMasterNet and the Intesis Multi-System Adapter are leading-edge solutions in the realm of HVAC integration technology. With their distinct features, broad compatibility, and user-friendly installation processes, they stand as the ideal choices for HVAC control in both residential and commercial settings. As we venture further into the evolving world of building automation, these systems represent the roadmap towards a future of smart, interconnected, and efficient built environments.
