- Display of manually activated restart or pump venting function
Equipment
- Quick electrical connection with Wilo-Connector
- Blocking-current proof motor
- Particle filter
Twin-head pump function
- Main/standby mode (automatic fault-actuated switchover/time-dependent pump cycling). If the twin-head pump is to be operated in main/standby operation, the control mode and the delivery head or speed stage must be set so they are identical.
- Parallel operation (efficiency-optimised peak load activation and deactivation). If the twin-head pump is to be operated in parallel/peak-load operation, the control mode and the delivery head or speed stage must be set so they are identical.
- An additional switchgear is required for switching the pumps, e.g. in the event of a fault.
