Wilo-Connect module Yonos MAXO

The flexible solution for building management system integration.

The Wilo-Connect module enables the optimal integration of the Wilo-Yonos MAXO into the building management system. Dual pump management is already integrated with no additional components required.

The “Ext. OFF” function ensures a soft start. The power needed to activate the pump is significantly reduced, decreasing the impact on the upstream switching elements. The pump operation is indicated by means of a collective run signal. The module can be used both in new installations and to upgrade existing systems.

Your advantages

  • A universal module for the complete series that is suitable for single and twin-head pumps, for new installations and for retrofitting pumps that have already been installed
  • Dual pump management already integrated without the need for additional components
  • Plug connection allows easy installation
  • “Ext. OFF” function ensures soft switching on and off for the preservation of upstream switching elements
  • Monitoring of operational readiness via the building management system using collective run and fault signals
  • Integrated dual pump management with fault indication for the pump affected and automatic switchover in case of a fault


The ‘Wilo-Connect-Module Yonos MAXO’, which allows for additional features on the existing Wilo-Yonos MAXO pump range, enabling greater energy saving capabilities.

The highly anticipated module gives users greater flexibility by enhancing the functionality of the Wilo-Yonos MAXO. It will also allow for integration into building management systems (BMS) with volt free contacts, fault/alarm signal, enable signal, run signal and dual pump management/integral changeover control for smooth operation when no BMS is on site.

Dual pump management gives auto changeover of twin head pumps on a time or failure basis where no BMS is on site, this means there is no need for a manual changeover by an operative.

The Wilo-Yonos MAXO already has multiple variable speed setpoints that give the pump a far greater level of control, thus more energy saving when fitting into a new or existing systems. In some cases the pump can have a payback time of less than a year, making it an incredibly energy efficient and economical solution.

Providing a competitive option to the market, when combined with the Connect Module, the Wilo-Yonos MAXO offers up to 32 variable speed setpoints and multiple alarm warning codes that can help indicate if there is a system issue or pump issue, error codes and alarms can even indicate if there is dirt in the systems or if the pumps is running dry - eliminating any potential failure. The pump is also physically much smaller than a lot of competitors modern products, which makes it much easier to fit when replacing older fixed speed pumps.
