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.

  • 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
