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 normally closed contact, or SBM collective run signal as potential-free normally open 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
