Wiring for accessories not supplied
When the pressure set point is given by the CVF type remote control or the 0-10V output, the factory-fit
-
ted potentiometer in the controller must be disconnected.
When the speed set point 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.

5.7.2 Adjusting the pressure set point
By potentiometer, CVF type remote control or 0-10V output.
By default the roof fan is set to obtain the pressure in bold in the table.
The potentiometer in the controller allows you to change the pressure set point.
The set point can be given by a CVF type remote control or a 0-10V output.
Correspondence table between the potentiometer graduation, the voltage applied on terminal 7 and the
pressure set point.
Note
: After each adjustment wait 1 minute for the fan speed to stabilize.
