Speed adjustment 0 / LS / HS (adjustable LS)
The adjustment can be done by a BCCA type 2S 0 / LS / HS switch.
The low speed is adjusted with the controller potentiometer.
The high speed is the roof fan speed with a control signal of 10V.
Speed adjustment 0 / LS / HS (adjustable LS and HS)
The adjustment can be done with a VRPZ voltage variator.
The low speed and the high speed are adjusted with the VRPZ, see VRPZ operating instructions.
Speed adjustment by the Modbus BMS
The adjustment can be done with a Modbus BMS . To know the parameters of the Modbus connection,
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.

Single-phase - CAV constant flow rate control
During operation at constant flow rate, the controller regulates the speed of the roof fan to obtain the set
point flow rate. A display installed under the cap indicates the flow rate measured in m
3
/h. The flow rate
set point can be adjusted by the potentiometer in the controller, by a CVF ON/OFF + variation remote
control, by an external 0-10V output or by Modbus BMS.
