13.2 Operating mode
Possible operating modes:
• Normal
The pump runs according to the selected control
mode.
•Stop
The pump stops.
•Min.
You can use the minimum curve mode in periods
in which a minimum flow is required. When
operating according to the minimum curve, the
pump is operating like an uncontrolled pump.
•Max.
You can use the maximum curve mode in periods
in which a maximum flow is required. When
operating according to the maximum curve, the
pump is operating like an uncontrolled pump.
• Manual
The pump is operating at a manually set speed.
In Manual the setpoint via bus is over-ruled. See
section 13.3 Set manual speed.
• "User-defined speed"
The motor is operating at a speed set by the
