Due to limited number of symbols in segment display, modbus addresses of "CUSTOM" device are entered as
HIGH and LOW bytes in hexadecimal (HEX) system. Using buttons B2 and B3, select HIGH or LOW bytes, "H.00"
and "L.00" are displayed respectively.
Modbus register read and record tool
Modbus register read and record tool indicated in F.39 and F.40 items is useful when you want to set the unit's
parameters, which by default are not controlled by remote controller, but these parameters are accessible via
Modbus. F.39 is used for Holding type registers and F.40 used Coil registers.
Using the Tool:
1. Modbus register address is indicated and confirmed by "MAX" button.
2. The tool reads the address value and shows on a segmental display (the value flashes).
3. Change the value with "+" and "-" button and confirm with the MAX button.
4. The tool records the value to indicated register and return to the service menu.
Air flow handling tool
Service menu F.45 is used to adjust air flow for different modes. Air flow handling tool operates with MCB and
PRV controllers.
Tool operation instruction:
1. Select desired air flow, what you want to control: SF.1, SF.2, SF.3, SF.4, EF.1, EF.2, EF.3 or EF.4. (SF and EF
determine, for which fan airflow will be modified; SF – air supply fan, EF – air exhaust fan. Number determines
speed/mode, for which air flow will be modified).
2. Equipment switches to the mode/speed, what was selected. Value from the controller is shown on the split
screen.
3. By pressing B4 and B6 you may change values (from 0 up to 100%). Fans speed/airflow changes automatically.
4. By pressing B5 you may exit airflow handling tool. Adjusted settings are saved on controller.
5. In order to change other airflow setting, please repeat steps 1-4.

erly when PRV automation is on the Compatibility mode.
