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 VLT
adjustable frequency drive. 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 VLT driven pump.
Description of choice:
Select the pump combination and capacities
from the choices offered.
