Your advantages
- LED display provides complete transparency of set delivery head, speed stage or possible errors
- Simple adjustment over three speed stages when replacing an uncontrolled standard pump
- Easier electrical connection using the Wilo plug
- System availability ensured via collective fault signal
- Compact design and proven ease of use
Glandless circulator with flange connection, EC motor with automatic power adjustment.
Application
Hot-water heating systems of all kinds, air-conditioning systems, closed cooling circuits, industrial circulation systems.
Equipment/function
Operating modes:
- Δp-c for constant differential pressure
- Δp-v for variable differential pressure
- Setting the operating mode
- Setting of pump output (delivery head)
- Infinitely variable power adjustment according to the operating mode
- Deblocking function
- Soft start
- Integrated full motor protection
- Collective fault signal (potential-free NC contact)
- Fault signal light
- LED segment display for displaying the delivery head and fault codes
- Main/standby operation: for an automatic fault-actuated switchover, a corresponding switchgear must be provided on-site
- Predefined control mode and set delivery head must be identical for both 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
