Comment

**NOTE** In the event of a requirement for capacity control via an external control signal and connection to a bus protocol, the Stratos MAXO must be used. Yonos MAXO does not support these features. For further information, contact Wilo Customer Support, telephone 01283 523 000
Fits without any modification of piping.
Replacement pump has higher capacity.
This Pump is equipped with alarm output (SSM) as standard. Additonal functions (external on/off, external operation indication) can be added with the simple install of the Connect-Module. One Connect-Module would be required per pump head.

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
