Manual functions

• Setting the operating mode
• Setting of pump output (delivery head)
• Venting function

Automatic functions

• Infinitely variable power adjustment according to the operating mode
• Automatic deblocking function

Signal and display functions

• Display of power consumption in W

Equipment

• Quick electrical connection with Wilo-Connector
• Venting function
• Blocking-current proof motor
• Particle filter

Double pump function

• Main/standby mode (automatic fault-actuated switchover/time-dependent pump cycling). If the double pump is to be operated in the main/standby mode, the control mode and the delivery head must be set so they are identical.
• Parallel operation (efficiency-optimised peak-load activation and deactivation). If the double pump is to be operated in parallel/peak-load operation, the control mode Δp-c must be set with the same delivery head.

An additional switchgear is required for switching the pumps, e.g. in the event of a fault.
