Benefits

Need	Problem	Solution
Manage complex configuration	Configuration of advanced parameters is often a complex task because menu navigation is complex and not intuitive	UCS software helps you easily set all the parameters and permit to save the configuration as a template and write it in just a click. The programming software can be connected to your phone or tablet also via Bluetooth using OPTOPROG, the Carlo Gavazzi optical interface.
Fast installation	Wire connection is a long procedure	Easily connect wires to WM30 and accessory modules, all equipped with detachable terminals

Need	Problem	Solution
Multi-tariff energy management	With standard meters, complex tariff management is not applicable	Easily manage any tariff model, with the embedded real time clock and calendar functions, up to 6 tariffs.

Need	Problem	Solution
Limiting the p/n to be purchased	Managing too many part numbers is not effective, and limits the production flexibility	Thanks to the modular concept, the same unit is compatible with many different protocols just changing the additional module.
