High-Efficiency Pump Control with the Wilo-Stratos MAXO

The Wilo-Stratos MAXO is a high-efficiency HVAC circulator pump designed for modern commercial buildings and advanced building automation systems (BAS). Built for reliability and intelligent performance, this smart pump can be easily integrated into heating, cooling, air conditioning, ventilation, and domestic hot water systems.

With built-in connectivity and flexible control options, the Stratos MAXO allows engineers, contractors, and facility managers to optimize HVAC system efficiency, energy consumption, and building performance.

Why Circulator Pumps Matter

Modern HVAC systems depend on equipment that can communicate with building management platforms. The Wilo-Stratos MAXO is designed for simple integration with common HVAC control networks, including:

• BACnet IP
• Modbus TCP
• Analog and digital control signals

Optional CIF communication modules allow the pump to easily connect to existing building automation and energy management systems, giving operators centralized visibility and control of hydronic circulation performance.

This makes the Stratos MAXO an excellent solution for commercial HVAC systems in hospitals, schools, office buildings, manufacturing facilities, and large residential complexes.

Faster Installation and Commissioning with Bluetooth Connectivity

The Wilo-Stratos MAXO includes integrated Bluetooth communication, allowing installers to configure and commission the pump directly from a mobile device using the Wilo-Assistant App.

Technicians can:

• Configure pump settings remotely
• Commission equipment in tight or hard-to-reach mechanical rooms
• Monitor pump performance
• Adjust operating parameters without physical access to the pump

This capability significantly reduces HVAC installation time and startup costs.

Energy-Efficient HVAC Pump Performance

Energy efficiency is a major focus in commercial building design, and the Wilo-Stratos MAXO delivers excellent performance with an Energy Efficiency Index (EEI) as low as ≤ 0.17.

Advanced energy-saving features include:

Multi-Flow Adaptation
Automatically adjusts pump flow to match the requirements of connected HVAC circuits.

No-Flow Stop
Stops the pump when demand drops to zero, reducing unnecessary energy consumption.

Dynamic Output Control
Automatically adapts pump performance to changing system demand without requiring manual setpoints.

These intelligent controls help reduce HVAC energy use, operating costs, and overall building energy consumption.

Remote Monitoring and Smart Building Connectivity

With Smart Connect functionality available through the Wilo-Assistant App, operators can remotely access pump data and system performance.

Facility managers can:

• Monitor operating data in real time
• Access system diagnostics
• Adjust pump settings remotely
• Optimize HVAC performance without visiting the mechanical room

When paired with the optional Wilo Net gateway, the Stratos MAXO can integrate into remote monitoring platforms, enabling advanced facility management and predictive maintenance strategies.

Flexible Pump Configurations for Commercial HVAC Systems

The Wilo-Stratos MAXO is available in several configurations to meet the needs of different system designs:

• Single pump configuration
• Dual pump configuration for redundancy
• Domestic hot water circulation version (Stratos MAXO-Z)

These options allow engineers to specify the right solution for commercial hydronic heating, chilled water systems, domestic hot water recirculation, and large building HVAC applications.

Key Benefits of the Wilo-Stratos MAXO

• High-efficiency ECM circulator pump for HVAC systems
• Seamless integration with BACnet and Modbus BAS networks
• Bluetooth commissioning for faster installation
• Advanced energy-saving functions to reduce operating costs
• Smart connectivity for remote monitoring and control
