Premium smart-pump Wilo-Stratos MAXO

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

Control modes:

  • Permanent, automatic performance adaptation 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.)
  • Needs-based volume flow optimisation of the feeder pump through connectivity and communication between multiple pumps (Multi-Flow Adaptation).
  • Constant volume flow (Q-const.)
  • Differential pressure control (dp-c) to a remote point in the pipe network (index circuit evaluator)
  • Constant differential pressure (dp-c)
  • Variable differential pressure (dp-v) with the option to set the nominal duty point
  • Constant speed (n-const.)
  • User-defined PID control

Functions:

  • Heat quantity measurement
  • Cooling quantity measurement
  • Pump automatically deactivates when no flow is detected (No-Flow Stop)
  • Switchover between heating and cooling mode (automatic, external or manual)
  • Adjustable volume flow limiter using the Q-Limit function (Qmin. and Qmax.)
  • Operating modes of twin-head pumps: Efficiency-optimised parallel operation for dp-c and dp-v, main and standby operation
  • Ability to save and restore configured pump settings (3 restoration points)
  • Fault and warning messages shown in plain text with advice on resolving the issue
  • Pump venting function for automatic venting of the rotor chamber
  • Automatic setback operation
  • Automatic deblocking function and integrated full motor protection
  • Dry-running detection

Display:

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

Version:

  • 2 configurable analogue inputs: 0–10 V, 2–10 V, 0–20 mA, 4–20 mA and commercially available PT1000; +24 V DC power supply
  • 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, heating/cooling, manual override (uncoupled from building automation), operation lock (key lock and remote operation configuration protection))
  • 2 configurable signal relays for operational and fault messages
  • Slot for Wilo-CIF modules with interfaces for building automation (BA) (optional accessories: Modbus RTU CIF Module, BACnet MS/TP, LON and PLR)
  • Wilo Net as a 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 with definable pump speed for exceptional circumstances, e.g. bus communication or sensor value malfunction
  • Graphic colour display (4.3 inches) with one-button manual operation
  • Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface (no further accessories required)
  • Integrated double pump management (double pumps are prewired) when using 2 single pumps as double pump unit (connection via Wilo Net)
  • Cable break detection when using an analogue signal (in connection with 2–10 V or 4–20 mA)
  • Outdoor installation with weather protection possible in accordance with the installation and operating instructions
  • Pre-set date and time
  • Thermal insulation shell for heating applications
