Your advantages
  • High drinking water hygiene ensured through collective fault signal
  • Energy-saving due to high-efficiency hydraulics and synchronous motor
  • Complete transparency of the delivery head, speed and possible faults thanks to its LED display
  • Simple adjustment over three speed stages using the green Knob when replacing an uncontrolled standard pump
  • Easier electrical connection thanks to the Wilo-Plug
  • Compact design and proven user-friendliness
The most efficient solution for domestic hot water circulation in larger buildings.

The Wilo-Yonos MAXO-Z is an efficient circulator for the hygienically safe provision of domestic hot water in commercial buildings. Thanks to its LED display, it gives you complete transparency regarding the delivery head, speed stage or any possible faults. The compact construction and Wilo plug for the electrical connection simplifies the installation. The Green Button makes pump operation simple.

Connect-Module Yonos MAXO
Item no.: 2210108

The Wilo-Connect module Yonos MAXO is a retrofittable plug-in module for Wilo-Yonos MAXO/Yonos MAXO-D/Yonos MAXO-Z pumps.
The Wilo-Connect module Yonos MAXO is installed on the electronic module of the pump at the position of the Wilo plug.

Utilisation of the Wilo-Connect moduleYonos MAXO dispenses with external contactors and other switchgears as well as the associated installation workload. The load of customer-side switchgears (relays) due to high starting currents is reduced to a minimum by the Connect module Yonos MAXO.

Equipment/function
  • Run signal display
  • SSM collective fault signal as potential-free NC contact
  • SBM collective run signal as potential-free NO contact
  • Overriding Off control input (External Off)
  • Integrated dual pump management with the functions:
  • Main/standby operation with runtime-dependent (24 h) switchover from main to standby pump
  • Fault-sensitive switchover to operational standby pump
