Yonos MAXO is a glandless circulation pump with threaded connection or flange connection, EC motor with automatic power adjustment. It is used in hot water heating, air conditioning, cooling and industrial circulation systems.

Key features

  • LED display for the indication of set delivery head and error messages
  • Simple adjustment when replacing an uncontrolled standard pump with preselectable speed stages, e.g. Wilo-TOP-S
  • Electrical connection with Wilo plug
  • System availability ensured via collective fault signal
  • Pump housing with cataphoretic (KTL) coating protects against corrosion due to condensation formation

Applications

  • Hot-water heating systems
  • Air-conditioning systems
  • Closed cooling circuits
  • Industrial circulation systems

Connect-Modules Yonos MAXO

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.

  • 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
