Circulation pump Wilo-Stratos MAXO 80/0.5-6 PN6

Wilo-Stratos MAXO Smart Premium Pump

Introducing the Wilo-Stratos MAXO inline glandless pump, a top efficiency device equipped with an EC motor and advanced electronics for electronic capacity adjustment. This pump is designed to handle hot water, cold water and a mixture of water and glycol, providing high energy efficiency (EEI ≤ 0.17 or ≤ 0.19, depending on the version)

Types of control

• Wilo-Dynamic Adapt plus - constant, automatic adaptation of output to system requirements without the need for setpoints, enabling energy savings of up to 20% compared to dp-v control mode
• Fixed temperature (T-const.)
• Constant differential temperature (dT-const.)
• Multi-Flow Adaptation - demand-driven optimization of the pump's rotary flow by connecting and communicating with several devices
• Constant flow (Q-const.)
• Control of differential pressure dp-c at a remote point in the pipeline (erroneous point control)
• Constant differential pressure (dp-c)
• Variable differential pressure (dp-v) with nominal operating point input option
• Constant speed (n-const.)
• User-defined PID control

Functions

• Heat quantity registration
• Registration of cold quantity
• Automatic shutdown when zero flow is recognized (No-Flow Stop)
• Switching between heating and cooling modes (automatic, external and manual)
• Adjustable flow limitation thanks to Q-Limit function (Qmin. and Qmax.)
• Type of operation of dual pumps - efficiency-optimized operation with connection for dp-c and dp-v, enabling operation in basic or reserve mode
• Saving and restoration of configured pump settings (3 restoration points)
• Failure and warning signaling in text form with diagnostic assistance
• Impeller chamber venting function
• Automatic night setback operation
• Automatic non-locking function and built-in full motor protection
• Dry operation detection

Version and configuration

• 2 configurable analog inputs: 0-10 V, 2-10 V, 0-20 mA, 4-20 mA and standard PT1000; power supply from +24 V DC
• 2 configurable digital inputs (Ext. Off, Ext. Min, Ext. Max, heating/cooling, manual override capability - building automation paired, key lock and remote control configuration protection)
• 2 configurable relays for signaling operation and failure messages
• Wilo CIF module slot with interfaces for building automation (optional accessories: CIF modules Modbus RTU, Modbus TCP, BACnet MS/TP, BACnet IP, LON, PLR, CANopen)
• Wilo Net - a bus system that allows Wilo products to communicate (including Multi-Flow Adaptation, dual pump integration, Wilo-Smart Gateway)
• Integrated temperature sensors
• Automatic fail-safe mode - predefined pump speed in emergency situations, e.g., communication shutdown or incorrect sensor values
• Graphic color display (4.3 inches) with one-button operation via manual operation module
• Bluetooth interface - allows reading and setting of operation data and protocol generation (Wilo-Assistant application)
• Dual pump operation management - possibility to wire two single pumps as a dual pump unit using the Wilo Net system
• Ability to recognize analog signal wire breaks (for 2-10 V or 4-20 mA)
• Outdoor positioning with protection against climatic factors according to the installation and operating instructions
• Date and time set as standard
• Thermal insulation covers for use in heating systems
