Adjusting the flow rate set point,
By potentiometer, CVF type remote control or 0-10V output.
Adjustment of the flow rate set point by potentiometer, CVF type remote control or 0-10V output.
The potentiometer in the controller allows you to change the flow rate set point.
The display under the cap shows the calculated flow rate.

By Modbus BMS
The flow rate set point can be given by a Modbus BMS set point. To find the settings of the Modbus con
-
nection, refer to § "5.2.4 Modbus connection - Connection to a BMS".
After you wired your Modbus link:
Turn on the power to connect yourself to the controller. The roof fan wheel must be stopped.
