                                                            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.
