Wilo-Stratos

Series description

Your advantages

  • Energy savings due to greater system efficiency with the Q-Limit function (volume flow limiter)
  • Improved Energy Efficiency Index (EEI) ≤ 0.20 for all single pumps
  • Enhanced display for better readability and ease of operation
  • Space-saving installation thanks to compact design and variable-orientation LC display
  • Modular concept for connection of all conventional bus systems (e.g. Modbus, BACnet, CAN, LON and PLR)
  • Tried-and-tested quality and reliability

Phasing out program

After 19 successful years, the Wilo-Stratos high-efficiency pump will be removed from our product range at the end of the year. It will be fully superseded by the new Wilo-Stratos MAXO smart pump. The successful era of the Stratos series will continue with the Stratos MAXO’s new pump technology.

Construction

Glandless circulator with threaded connection or 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

  • Constant speed (n=constant)
  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • Δp-T for temperature-controlled differential pressure (programmable via IR-Stick, IR-Monitor, Modbus, BACnet, LON or CAN)
  • Q limit for limiting the maximum volume flow (setting only via IR-stick)

Manual functions

  • Setting the operating mode
  • Differential pressure setpoint setting
  • Setting automatic setback operation
  • Setting the pump ON/OFF
  • Setting the speed (manual control mode)

Automatic functions

  • Continuous power adjustment according to the operating mode
  • Automatic setback operation
  • Deblocking function
  • Soft start
  • Full motor protection with integrated trip electronics

External control functions

  • "Overriding Off" control input (possible with Stratos IF-Modules)
  • "Overriding Min" control input (possible with Stratos IF-Modules)
  • "Analogue In 0 - 10 V" control input (remote speed adjustment) (possible with Stratos IF-Modules)
  • "Analogue In 0 - 10 V" control input (remote setpoint adjustment) (possible with Stratos IF-Modules)

Signal and display functions

  • Collective fault signal (potential-free NC contact)
  • Individual run signal (potential-free NO contact) (possible with Stratos IF-Modules)
  • Fault signal light
  • LCD display for indication of pump data and error codes

Data exchange

  • Infrared interface for wireless data exchange with IR-Stick/IR-Monitor
  • Modbus RTU serial digital interface for connection to building automation BA via RS485 BUS system (possible with Stratos IF-Modules)
  • BACnet serial digital interface MS/TP Slave for connection to building automation BA via RS485 BUS system (possible with Stratos IF-Modules)
  • CAN serial digital interface for connection to building automation BA via CAN BUS system (possible with Stratos IF-Modules)
  • LON serial digital interface for connection to a LONWorks network (possible with Stratos IF-Modules)
  • PLR serial digital interface for connection to BA via Wilo interface converter or company-specific coupling modules (possible with Stratos IF-Modules)

Dual pump management (twin-head pump or 2 x single pumps)

  • Main/standby operation (automatic fault-actuated switchover/time-dependent pump cycling): various combinations with Stratos IF-Modules (accessories) possible
  • Parallel operation (efficiency-optimised peak load activation and deactivation): various combinations with Stratos IF-Modules (accessories) possible
