Circulation pump Wilo-Stratos MAXO 40/0.5-12 PN6/10

The Wilo-Stratos MAXO Smart Premium pump is a glandless Inline pump with the highest efficiency, equipped with an EC motor and an advanced electronic capacity matching system. The unit is designed for hot water, cold water and water-glycol mixtures, achieving a very low EEI - ≤ 0.17 or ≤ 0.19, respectively, depending on the pump type

The control system offers multiple modes, including

• Wilo-Dynamic Adapt plus: constant, automatic adaptation of power to the system's requirements without the need for setpoints, providing energy savings of up to 20% compared to dp-v control mode
• Constant temperature control (T-const.)
• Differential constant temperature control (dT-const.)
• Multi-Flow Adaptation: optimization of rotary flow by communicating with several pumps
• Constant flow mode (Q-const.)
• Remote point differential pressure control (dp-c) and variable differential pressure control (dp-v) with nominal operating point setting option
• Constant speed (n-const.)
• User-defined PID control

Additional pump functions include

• Heat and cold quantity recording
• Automatic shutdown when zero flow is detected (No-Flow Stop)
• Switching between heating and cooling modes - automatically, externally or manually
• Adjustable flow limitation by Q-Limit function (Qmin and Qmax setting)
• Optimized operation of dual pumps (primary mode and reserve mode) by connecting for dp-c and dp-v
• Saving and restoring settings (up to 3 restore points)
• Failure and warning signaling in text form with help
• Function of automatic venting of the rotor chamber
• Automatic operation in night setback mode
• Non-locking function and full motor protection
• Dry operation detection

The display can read the type of control, setpoint, flow rate, temperature, power consumption, current consumption and active signals (e.g. STOP, No-Flow Stop), among others

The Smart Premium system version includes

• 2 configurable analog inputs (0-10 V, 2-10 V, 0-20 mA, 4-20 mA and standard PT1000) with +24 V DC power supply
• 2 configurable digital inputs (e.g. Ext. Off, Ext. Min, Ext. Max, heating/cooling, manual override, 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 modules: Modbus RTU, Modbus TCP, BACnet MS/TP, BACnet IP, LON, PLR, CANopen)
• Wilo Net system for communication between Wilo products (including Multi-Flow Adaptation; integration of dual pumps and Wilo-Smart Gateway)
• Integrated temperature sensors
• Automatic fail-safe mode (preset speed in case of communication failure or erroneous sensor readings)
• Graphic 4.3-inch color display with manual operation module (one button)
• Reading and setting of operation data and preparation of commissioning report via Bluetooth (Wilo-Assistant application)
• Management of dual pump operation integrated (combination of two single pumps into a dual unit, communication via Wilo Net)
• Analog signal break detection capability (using 2-10 V or 4-20 mA signals)
• Possibility of external mounting with protection against climatic factors according to the instructions
• Serial date and time setting
• Thermal insulation covers for heating systems
