WILO Wet Runner Premium Smart Pumps Stratos MAXO 50/0.5-9 PN6/10, DN50, 451W

Premium Smart Pump Wilo-Stratos MAXO

High-efficiency inline glandless circulator pump with EC motor and electronic power adjustment. Can be used for heating water, cold water, and water-glycol mixtures. Energy Efficiency Index (EEI) between ≤0.17 and ≤0.19, depending on the pump type.

Control Modes:

• Permanent, automatic power adjustment to system requirements without setpoint specification Wilo-Dynamic Adapt plus (factory setting). Up to 20% energy saving compared to dp-v control mode.
• Constant temperature (T-const.)
• Constant differential temperature (dT-const.)
• Demand-driven flow optimization of the booster pump through networking and communication with multiple pumps (Multi-Flow Adaptation).
• Constant flow rate (Q-const.)
• Differential pressure control dp-c at a remote point in the pipe network (worst point control)
• Constant differential pressure (dp-c)
• Variable differential pressure (dp-v) with the option of nominal operating point input
• Constant speed (n-const.)
• User-defined PID control

Functions:

• Heat quantity measurement
• Cooling quantity measurement
• Automatic pump shutdown on zero flow detection (No-Flow Stop)
• Switching between heating and cooling operation (automatic, external or manual)
• Adjustable flow limitation via Q-Limit function (Qmin. and Qmax.)
• Dual pump operating modes: Efficiency-optimized addition operation for dp-c and dp-v, main/standby operation
• Saving and restoring configured pump settings (3 restore points)
• Fault/warning message display in plain text, including troubleshooting recommendations
• Venting function for automatic venting of the rotor chamber
• Automatic night setback
• Automatic deblocking function and integrated full motor protection
• Dry-running detection

Display:

• Control mode
• Setpoint
• Flow rate
• Temperature
• Power consumption
• Electrical consumption
• Active influences (e.g. STOP, No-Flow Stop)

Design:

• 2 configurable analogue inputs : 0-10V, 2-10V, 0-20mA, 4-20mA and standard Pt1000, power supply with +24VDC
• 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, Heating/Cooling, Manual Override (Building Automation decoupled), Operating Lock (Keypad lock and remote control configuration protection))
• 2 configurable signal relays for operating and fault messages
• Slot for Wilo-CIF modules with interfaces for building automation (Optional accessories: CIF modules Modbus RTU, Modbus TCP, BACnet MS/TP, BACnet IP, LON, PLR, CANopen)
• Wilo Net as Wilo system bus for communication between Wilo products, e.g. Multi-Flow Adaptation, dual pump operation and Wilo-Smart Gateway
• Integrated temperature sensor
• Automatic emergency operation in special conditions (pump speed definable) e.g. in case of bus communication or sensor value failure
• Graphical color display (4.3 inch) with one-button manual control
• Reading and setting operating data as well as e.g. creating a commissioning report via Bluetooth interface (without further accessories) using the Wilo Assistant App
• Dual pump management integrated (dual pumps are pre-wired), when using 2 individual pumps as a dual pump unit, connection via WILO Net
• Cable break detection for analog signal (in conjunction with 2-10V or 4-20mA)
• Outdoor installation with weather protection possible according to installation and operating instructions
• Date and time pre-set
• Thermal insulation shell for heating applications
• 5-year warranty
