• LED indicator provides indication of setpoints for head, speed step or possible errors
• Easy adjustment with three speed steps when replacing an unregulated standard pump
• Simplified electrical connection via Wilo-Connector
• System availability (reliability) through generalized fault indication
• Compact design and safe, simple handling

Type
Glandless circulation pump with flange connection, EC motor with automatic speed adjustment.

Application
Heating systems, air-conditioning systems, closed cooling circuits, industrial circulation systems.

Equipment/function
Modes of operation

• Δp-c for constant differential pressure
• Δp-v for variable differential pressure

Manual override

• Setting of operating modes
• Adjustment of pump capacity (head)

Automatic control

• Infinitely variable speed adjustment depending on the mode of operation
• Lockout function
• Soft start
• Full motor protection built in

Alarms and display

• Generalized fault indication (potential-free NC contact)
• Light fault indication
• Displays head value and error codes

Dual pump function

• Main/backup operating mode: to realize automatic change-over in case of malfunction, the customer must provide an appropriate control unit.
• Both pumps must have identical control methods and identical setpoint heads.

Equipment

• Spigot for pump casing (on pumps with threaded connections to the pipe)
• Quick electrical connection via Wilo-Stecker. For connection of mains and SSM, with integrated cable gland
• For pumps with flange connections: Flange versions
• Standard version for pumps DN 32 to DN 65: Combination flange PN 6/10 (flange PN 16 in accordance with EN 1092-2) for counter flanges PN 6 and PN 16
• Standard version for pumps DN 80 / DN 100: Flange PN 6 (designed PN 16 in accordance with EN 1092-2) for counter flange PN 6
