(PUMP COMBINATION)
Value:
(See options in table below)
Function:
The combinations of pumps and their rated capacities
are selected in this parameter. The lead pump (or
fan) with the cascade contol option must have a
capacity of 100% and its speed is controlled by the
AFD. This enables the highest accuracy in regulation
of the system. In Standard cascade control mode,
additional pumps can be either 100%, 200% or
300% relative to the AFD driven pump.
Description of choice:
Select the pump combination and capacities
from the choices offered.
