- 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
Equipment
- Wrench attachment point on pump body (for threaded pipe union pumps with P2≤100 W)
- For flange-end pumps: Flange versions
- Standard version for DN 40 to DN 65 pumps: PN 6/10 combination flange (PN 16 flange according to EN 1092-2) for PN 6 and PN 16 counter flanges,
- Special version for DN 40 to DN 65 pumps: PN 16 flange (according to EN 1092-2) for PN 16 counter flange,
- Plug-in position for optional extension with Wilo-IF-Modules
- Thermal insulation as standard
