WILO Wet Rotor Premium Smart Pumps Stratos MAXO 40/0.5-4 PN6/10, DN40, 115W

Wilo-Stratos MAXO Premium Smart Pump

High-efficiency inline glandless 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 &le,0.17 and &le,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 savings compared to dp-v control mode.
• Constant temperature (T-const.)
• Constant differential temperature (dT-const.)
• Demand-driven flow optimisation 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 (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 measurement
• Cooling quantity measurement
• Automatic pump shutdown on zero flow detection (No-Flow Stop)
• Switching between heating and cooling mode (automatic, external or manual)
• Adjustable flow rate limitation through Q-Limit function (Qmin. and Qmax.)
• Twin pump operating modes: Efficiency-optimised addition mode for dp-c and dp-v, duty/standby mode
• Saving and restoring configured pump settings (3 restoration points)
• Fault/warning message display in plain text including troubleshooting recommendations
• Ventilation 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

Design:

• 2 configurable analog 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 (GA) (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 colour display (4.3 inches) with one-button manual control
• Reading and setting operating data as well as e.g. creating a commissioning report via Bluetooth interface (without additional accessories) using the Wilo Assistant App
• Twin pump management integrated (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 pre-set
• Thermal insulation shell for heating applications
• 5-year warranty
