WILO Wet Rotor Premium Smart Pumps Stratos MAXO 32/0.5-12 PN6/10, DN32, 273W

Premium Smart-Pump Wilo-Stratos MAXO

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

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 mode.
• Constant temperature (T-const.)
• Constant differential temperature (dT-const.)
• Demand-driven volume flow optimization of the booster 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 operation (automatic, external or manual)
• Adjustable volume flow limitation via Q-Limit function (Qmin. and Qmax.)
• Double pump operating modes: Efficiency-optimized addition mode for dp-c and dp-v, main/standby operation
• Saving and restoring configured pump settings (3 recovery 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
• Set point
• Volume flow
• 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 commercial Pt1000, power supply with +24VDC
• 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, Heating/Cooling, Manual override (BMS decoupled), Operation lock (button lock and remote control configuration protection))
• 2 configurable signal relays for operating and fault messages
• Slot for Wilo-CIF modules with interfaces for building management system BMS (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, double 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 failure
• Graphical color display (4.3 inch) with single-button manual operating level
• Reading out and setting operating data and e.g. creating a commissioning report via Bluetooth interface (without further accessories) using the Wilo Assistant App
• Double pump management integrated (double pumps are pre-wired), when using 2 single pumps as a double pump unit, connection via WILO Net
• Cable break detection for analogue signal (in conjunction with 2-10V or 4-20mA)
• Outdoor installation with weather protection according to installation and operating instructions possible
• Date and time pre-set
• Thermal insulation shell for heating applications
• 5-year warranty
