iii constant curve mode – bms signal
When the Building Management System is to be used for
speed control it is necessary to disable sensorless control
and provide the unit with a 0-10vdc speed reference signal.
iv constant curve mode – potentiometer
To control the pump based on a 0-10v potentiometer signal
use the connections below.
iv.i full speed over ride
It may be required to run the pump at full speed without
automatic speed control (eg during system commissioning).
This can be achieved without programming changes by
making the connections below.
