Features:

• Can be used for all heating, ventilation and air-conditioning applications
• Preselectable control modes for optimum load adjustment: Δp-c (constant differential pressure), Δp-v (variable differential pressure)
• 3 speed stages (n = constant)
• LED for setting the setpoint and displaying error messages
• Electrical connection with the Wilo plug
• Fault lamp and contact for collective fault signal

The incredibly efficient pump Wilo-Yonos MAXO is electronically controlled. This Wilo Yonos Pump offers a glandless twin-head pump, synchronous motor according to ECM technology and integrated power control for continuous differential pressure control.

Each pump can be operated in individual operation (main/standby operation). For an automatic fault-actuated switchover, a corresponding switchgear must be provided on-site.
