Installation And Electrical Connection - Wilo Yonos ECO BMS Notice De Montage Et De Mise En Service

English
• Once power returns after a power interruption, the pump goes back into operation with
different start-up times, depending on the setting chosen. See chapter 10.2 for the
restart times.
• SSM: Faults always result in the activation of the collective fault signal ("SSM" via a relay).
The contact of the collective fault signal (potential-free normally closed contact) can be
connected to a building automation system. The internal contact is closed if the pump is
without power, if there is no fault or if there is a malfunction of the control module. The
performance of the SSM is described in chapters 7.2.2 and 10.1.
