How to change the Modbus address of the FCU 2160
a. In the FCU Communication window click the Change Address on
Device... button to open the Change Address window:

When changing the device address, the Unit Id is used as a unique
identifier of the device. The Unit Id can be found on a label mounted
on the device.
(If there is no other device connected that uses the same address as
the current device, you can find the Unit Id by typing the current
address into the Address field in the FCU Communication window
and clicking the Verify Communication button).
c. Click the OK button to confirm the settings and to close the Change
Address window.
d. In the FCU Communication window click the Verify
Communication button to check if communication is established
between the TankMaster work station and the 2160 FCU. The Unit
ID will appear when TankMaster finds the 2160.

installation procedure of the 2160 FCU.
