Tender text

Retrofittable plug-in module Wilo-Connect Module BMS for pumps with Wilo-Connectivity Interface (e.g. Stratos PICO) to expand the interface for building management systems (BMS).

The module is mounted to the electronic module via the Wilo-Connectivity interface of the pump (below the lockable module cover).

Equipment/function

  • Run signal display
  • Analogue input 0–10 V for setpoint specification
  • Signal display via relay output as changeover contact
  • SSM collective fault signal as potential-free NC contact
  • SBM collective run signal as potential-free NO contact
  • Control input with configurable functions:
    • Overriding OFF (external OFF), MIN (external MIN), MAX (external MAX)
  • 2 PG screwed connections, with rotatable vertical or horizontal alignment

Scope of delivery

  • BMS Wilo-Connect module
  • 2x M 20 threaded cable glands pre-assembled in vertical alignment
  • Installation and operating instructions
