WILO Wet Rotor Premium Smart Pumps Stratos MAXO 25/0.5-10 PN10, G11/2, 268W

Premium Smart Pump Wilo-Stratos MAXO

High-efficiency inline wet rotor pump with EC motor and electronic power adjustment. Can be used for heating water, chilled 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 adaptation to system requirements without setpoint specification Wilo-Dynamic Adapt plus (factory setting). Up to 20% energy saving compared to dp-v control.
• Constant temperature (T-const.)
• Constant differential temperature (dT-const.)
• Demand-oriented volume flow optimization of the feeder pump through networking and communication with multiple pumps (Multi-Flow Adaptation).
• Constant volume flow (Q-const.)
• Differential pressure control dp-c at a remote point in the pipe network (critical 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 detection
• Cooling quantity detection
• Automatic pump shutdown upon zero flow detection (No-Flow Stop)
• Switching between heating and cooling mode (automatic, external or manual)
• Adjustable volume flow limitation by Q-Limit function (Qmin. and Qmax.)
• Double pump operating modes: Efficiency-optimized addition mode for dp-c and dp-v, main/standby mode
• Save and restore configured pump settings (3 restore points)
• Fault/warning message display in plain text including troubleshooting recommendations
• Venting function for automatic de-aeration of the rotor chamber
• Automatic night setback
• Automatic deblocking function and integrated full motor protection
• Dry-running detection

Display:

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

Design:

• 2 configurable analog inputs: 0-10V, 2-10V, 0-20mA, 4-20mA and commercial Pt1000, power supply with +24VDC
• 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, Heating/Cooling, Manual Override (Building Automation decoupled), Operation 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 BA (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, twin 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 failure or sensor value loss
• Graphical color display (4.3 inch) with operation via single-button manual control level
• Reading and setting operating data and e.g. creating a commissioning report via Bluetooth interface (without additional accessories) using the Wilo Assistant App
• Integrated twin pump management (twin pumps are pre-wired), when using 2 single pumps as a twin 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 preset
• Thermal insulation shell for heating applications
• 5 years warranty
