• Energy savings thanks to increased system efficiency with Q-Limit (flow limitation)
• Enhanced EEI ≤0,23 in all twin pumps
• Optimized display for improved readability and control
• Small footprint due to compact design and position-independent LCD
• Modular concept for connection to all common bus systems (e.g. Modbus, BACnet, CAN, LON, PLR)
• Control system for twin pumps with additional IF modules
• Proven quality and reliability

Decommissioning program

The Wilo-Stratos high-performance pump, which has been a success for 19 years, will be completely phased out by the end of March 2020 and replaced by the new Wilo-Stratos MAXO smart pump. The new Wilo-Stratos MAXO pump technology will continue the success of the Stratos series.

Type

Double wet rotor circulator pump with flange connection, electronic commutated motor with automatic speed control

Application

Heating systems, air-conditioning systems, closed cooling circuits, industrial circulation systems

Heating/air conditioning systems, closed cooling circuits

Equipment/function

Operating modes

• Manual control mode (n = constant)
• Δp-c for constant differential pressure
• Δp-v for variable differential pressure
• Δp-T for temperature-dependent differential pressure (programmable via IR-Stick, IR-Monitor, Modbus, BACnet, LON or CAN)
• Q-Limit to limit the maximum flow (programmable only via IR-Stick)

Manual control

• Setting of operating modes
• Setting the flow rate
• Setting the automatic speed reduction mode
• Setting the pump ON/OFF
• Setting the speed (manual changeover)

Automatic control

• Flexible power adjustment depending on operating mode
• Automatic operation with reduction
• Disengagement function
• Fast start-up
• Full motor protection with integrated electronic shutdown

External control

• Control input «Off by priority» (possible with Stratos IF modules)
• Control input «Min power by priority» (possible with Stratos IF modules)
• Control input «Analog In 0 - 10V» (remote speed switching), possible with Stratos IF modules
• Control input «Analog In 0 - 10 V» (remote setpoint change), possible with Stratos IF-modules

Alarms and indication

• Separate/common fault alarm (potential-free NC contact), programmable with IR memory card/IR monitor
• Generalized fault alarm (potential-free NC contact)
• Separate operation alarm (potential free normally open contact), possible with Stratos IF modules
• Light Fault indicator
• LCD display for pump parameters and error codes

Data exchange

• Infrared interface for wireless data exchange with IR-Stick/IR monitor
• Serial digital interface Modbus RTU for connection to building automation system via RS485 bus system (possible with Stratos IF-modules)
• Serial digital interface BACnet MS/TP Slave for connection to building automation via RS485 bus system (possible with Stratos IF-modules)
• Serial digital CAN interface for connection to building automation via bus system (possible with Stratos IF-modules).
• LON serial digital interface for connecting to the LONWorks network (possible with Stratos IF modules)
• Serial digital interface
