Your advantages

• LED display for adjusting the setpoint in 0.1 m increments and showing effective consumption
• Electrical connection without tools using the Wilo-Connector
• Unique pump venting function per pump
• Twin-head pump for individual (Δp-c, Δp-v and constant speed) or parallel (Δp-c and constant speed) operation
• Very high starting torque for reliable starting

Construction
Glandless twin-head circulator with screwed connection, blocking-current proof EC motor and integrated electronic power control.

Application
All hot-water heating systems, air-conditioning applications, industrial circulation systems.

Equipment/function

• Display of manually activated restart or pump venting function

Equipment

• Quick electrical connection with Wilo-Connector
• Pump venting function
• Manual restart
• 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 C1, C2, C3 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 Δp-c must be set with the same delivery head or constant speed with identical speed stage C1, C2, C3.
• An additional switchgear is required for switching the pumps, e.g. in the event of a fault.
