Stratos MAXO-D 30/0,5-10 PN 16

Premium smart-pump Wilo-Stratos MAXO-D

High-efficiency in-line glandless twin-head pump with EC motor and electronic power adjustment. Can be used for chilled water, heating water and water/glycol mixtures. Energy efficiency index (EEI) between ≤ 0.17 and ≤ 0.19 depending on pump type.

Control modes:

• Permanent, automatic power adjustment to system requirements without setpoint specification Wilo Dynamic Adapt plus (factory setting). Up to 20% energy savings compared to dp-v control mode.
• Constant temperature (T-const.)
• Constant differential temperature (dT-const.)
• Needs-based volume flow optimisation of the feeder pump through connectivity and communication between multiple pumps (Multi-Flow Adaptation).
• Constant volume flow (Q-const.)
• Differential pressure control (dp-c) to a remote point in the pipe network (index circuit evaluator)
• Constant differential pressure (dp-c)
• Variable differential pressure (dp-v) with the option to set the nominal duty point
• Constant speed (n-const.)
• User-defined PID control

Functions:

• Heat quantity measurement
• Cooling quantity measurement
• Pump automatically deactivates when no flow rate is detected (No-Flow Stop)
• Switchover between heating and cooling mode (automatic, external or manual)
• Adjustable volume flow limiter using the Q-Limit function (Q_min. and Q_max.)
• Dual-pump operations: Efficiency-optimised parallel operation for dp-c and dp-v, main and standby operation
• Ability to save and restore configured pump settings (3 restoration points)
• Fault and warning messages shown in plain text with advice on resolving the issue
• Pump venting function for automatic venting of the rotor chamber
• Automatic night setback
• Automatic deblocking function and integrated full motor protection
• Dry-running detection

Display:

• Control mode
• Setpoint
• Volume flow
• Temperature
• Power consumption
• Electric consumption
• Active influences (e.g. STOP, No-Flow Stop)

Version:

• 2 configurable analogue inputs: 0-10 V, 2-10 V, 0-20 mA, 4-20 mA and commercially available Pt1000; +24 V DC power supply
• 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, heating/cooling, manual override (uncoupled from building automation), operation lock (key lock and remote operation configuration protection))
• 2 configurable signal relays for run signals and fault messages
• Slot for Wilo-CIF modules with interfaces for building automation BA (optional accessories: CIF modules Modbus RTU, Modbus TCP, BACnet MS/TP, BACnet IP, LON, PLR, CANopen)
• Wilo Net as a Wilo system bus for communication between Wilo products, e.g. Multi-Flow Adaptation; dual-pump operation and Wilo-Smart Gateway
• Integrated temperature sensor
• Automatic emergency operation with definable pump speed for exceptional circumstances, e.g. bus communication or sensor value malfunction
• Graphic colour display (4.3 inches) with one button manual operation level
• Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface (no further accessories required)
• Integrated dual-pump management (twin-head pumps are prewired) when using 2 single pumps as two-pump unit (connection via Wilo Net)
• Cable break detection when using an analogue signal (in connection with 2 – 10 V or 4 – 20 mA)
• Outdoor installation with weather protection possible in accordance with the installation and operating instructions
• Pre-set date and time
