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 fault 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 (double 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
