Also when it comes to link-ups to building automation via contacts and voltage or power interfaces, Wilo offers extensive functions.

In addition to communicative interfaces, Wilo also offers the control and signalling via classic multi-wire connections. Depending on the pump type, the connections are done either at the pump or the optional IF-Module or at an interface converter.

Interface converter
The AnaCon interface converter (or DigiCon-A in addition to DigiCon and DigiCon-Modbus) requires IF-Modules PLR and offers the following functions:
- Control input 0-10 V
- Control input Overriding Off (Ext. Off)
- Control input Overriding Max (Ext. Max)
- Control input Overriding Min (Ext. Min)
- Control input Overriding On (Ext. On)
- Collective fault signal (SSM)
- Individual run signal (EBM)

Control input 0-10 V or 0/4-20 mA  (setpoint or speed setting)
Depending on the pump type, the analogue control input can deliver a setpoint setting in the chosen control mode or a speed setting for the drive. The possible physical input value as well as the control type is given behind the correspondent series. The transmission function is specific for the application.

For these series, a correspondent input is part of the standard equipment:

- VeroLine IP-E/DP-E  0-10 V,  0/4-20 mA
  - pump curve: Control Input IP-E
- CronoLine IL-E/DL-E 0-10 V,  0/4-20 mA
  - pump curve: Control Input  IL-E
- CronoLine IL-E...BF/DL-E...BF 0-10 V 0/4-20 mA setpoint delta p-c, speed setting
  - pump curve: delta p-c 
  - pump curve: n-c
- MultiVert MVIE  0-10 V, 0/4-20 mA setpoint p, speed setting
  - pump curve: p-c
  - pump curve: n-c
- MultiVert MVIE 11 - 22 kW 0-10 V 0/4-20 mA speed setting
  - pump curve: Control Input MVIE

For other series, the following IF-Modules or optional modules are available:

- Stratos/Stratos-D/Stratos-Z 0-10 V setpoint delta p-c, delta p-v , delta p(T), speed setting: IF-Module Stratos SBM, IF-Module Stratos Ext. Off, IF-Module Ext. Min
  - pump curve: Control Input Stratos

  - pump curve: -p-c / p-v
  - pump curve: -n-c

Control input Overriding Off (Ext. Off)
