Switching speed stages
Setting the speed stages: 3 speed stages (2 speed stages for single-phase pumps with P2 ≥ 350 W)
Full motor protection with integrated electronic shutdown (standard equipment only for three-phase pumps with P2 ≥ 180 W and single-phase pumps P2 ≥ 350 W, optional for all types with Wilo-Protect Module-C)
Control input "Off. priority "(optional for all types with Wilo-Protect-Module C)
Separate / collective fault signaling (potential-free NC contact) (optional for all types with Wilo-Protect-Module C)
Generalized fault signaling (potential-free NC contact) (standard equipment only for 3 ~ pumps with P2 ≥ 180 W and 1 ~ pumps with P2 ≥ 350 W, optional for all types with Wilo-Protect-Module C)
Separate signaling for operation (potential-free normally open contact) (optional for all types with Wilo-Protect-Module C)
Protective winding contact (ZKO, potential-free NC contact) only for single-phase pumps with P2 = 180 W)
Fault indication light (standard equipment only for 3-phase pumps with P2 ≥ 180 W and for single-phase pumps with P2 ≥ 350 W, optionally for all types with Wilo-Protect Module C)
Direction of rotation indicator light (only for three-phase pumps)
Operating mode "main / standby" (automatic changeover of pumps by fault signal / timer): as an option for all types of pumps with Wilo-Protect Module C
