Wiring for accessories not supplied
When the flow rate set point adjustment is given by the CVF type remote control or the 0-10V output, the
factory-fitted potentiometer in the controller must be disconnected.
When the speed set point setting is given by the MODBUS BMS the factory-fitted potentiometer in the
controller must be disconnected,
as well as the shunt between terminals 13 and 15.
