Your advantages
Wilo-Stratos MAXO-D (North America)

A head start into the world of tomorrow

More efficiency, connectivity and comfort than ever before – the Wilo-Stratos MAXO and the Wilo-Stratos MAXO-D deliver the future of pump technology to your doorstep. The world’s first smart-pump* features tomorrow’s innovations that make your life easier today.


Your advantages

  • Intuitive operation by means of application-guided settings with the Setting assistant plus the combination of a new display and operating button using Green Button Technology.
  • Maximum energy efficiency thanks to the combination of optimized and innovative energy-saving functions (e.g. No-Flow Stop).
  • Optimum system efficiency thanks to new and innovative intelligent control functions, such as Dynamic Adapt plus, Multi-Flow Adaptation, T-const. and ΔT-const.
  • Latest communication interfaces (e.g. Bluetooth) for connection to mobile devices and direct pump networking for multiple pump control via Wilo Net.

Environmentally friendly features

  • Combination of optimised and innovative control modes provides maximum energy efficiency
  • Highest system efficiency with the innovative “Multi-Flow Adaptation” and energy savings of up to 80%
  • Sustainable and carbon-neutral production and processes in our European factories
  • Full transparency of the pump's operating status via remote access to save resources compared to on-site assessments

Equipment/function

Field of application

The pump facilitates an operation with highest system efficiency via precise setting of the control mode for the system-specific application (e.g. radiator, underfloor heating, ceiling cooling).

  • Heating
  • Radiator
  • Underfloor heating
  • Ceiling heating
  • Fan heater
  • Heat exchanger

Cooling

  • Ceiling cooling
  • Underfloor cooling
  • Air-conditioning devices
  • Heat exchanger

Heating and cooling combined

  • Automatic switchover

The following control modes are available depending on the selected application:

Control modes

  • Constant speed (control mode)
  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • Dynamic Adapt plus for continuous (dynamic) adjustment of the delivery rate to the current requirement
  • T-const. for constant temperature regulation
  • ΔT for differential temperature control
  • Constant Q for constant volume flow control
  • Multi-Flow Adaptation: Total volume flow determination through the feeder pump for the needs-based supply of secondary pumps in the heating circuit distributors
  • User-defined PID controller

Optional functions

  • Q-limitmax. for limiting the maximum volume flow
  • Q-limitmin. for limiting the minimum volume flow
  • No-Flow Stop (zero-flow-deactivation)
  • Automatic setback operation
  • Index circuit evaluator (Δp-c control with external actual value sensor)
  • Thermal disinfection detection (Stratos MAXO-Z)
  • Variable pitch of Δp-v pump curve

Manual settings

  • Selection of the field of application using the Setup Guide
  • Setting the related operating parameters
  • Nominal duty point: direct input of calculated duty point at Δp-v
  • Status display
  • Setting and resetting the energy meters (heating and cooling)
  • Pump venting function
  • Key lock for disabling the settings
  • Function for resetting the factory settings or the saved restoration points (parameter sets)
  • Parameterising the analogue inputs
  • Parameterising the binary inputs
  • Parameterising the relay outputs
  • Dual pump function (for 2 single pumps, which should be operated as twin-head pump)

Automatic functions

  • Power adjustment according to requirements for energy-efficient operation depending on the operating mode
  • Setback operation
  • Deactivation at zero flow (No-Flow Stop)
  • Soft start
  • Automatic troubleshooting routines (e.g. deblocking function)
  • Switchover heating/cooling mode
  • Full motor protection with integrated trip electronics

2 x digital inputs:

  • For potential-free control outputs or switch
  • Parametrizable functions:
    • Ext. Off
    • Ext. Min
    • Ext. Max
    • MANUAL (BMS-OFF)
    • Key lock
