Wilo-Stratos-D

Series description

Your advantages

  • Energy savings due to greater system efficiency with the Q-Limit function (volume flow limiter)
  • Improved Energy Efficiency Index (EEI) ≤0.23 for all twin-head 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)
  • Dual pump management via retrofittable IF-Modules:
  • Tried-and-tested quality and reliability

Construction

Glandless twin-head 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

  • 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

  • Individual/collective fault signal (potential-free NC contact) (programmable with the IR-Stick/IR-Monitor)
  • 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 IF-Modules 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
