About this app

Connect to and setup of any Danfoss LLS 4000/4000U liquid level switch with the LLS 4000 app. Commissioning, setup, and monitoring can all be performed quickly and conveniently with just a few taps on your smartphone. The LLS 4000 app connects remotely to any LLS 4000/4000U liquid level switch via Bluetooth. Once they are paired up, you can select between essential functions. For the non-SIL2 variant of the LLS 4000, the app enables you to select between several media1 and select switch function as normally open (NO) or normally closed (NC). You can also monitor performance, including temperature and frequencies. If you connect to a SIL2 variant, you do exactly the same as for the non-SIL2 variant except: A SIL2 variant is locked to a normally closed (NC) function and cannot be changed The app has two modes: Service mode for commissioning and monitoring. If you’re a contractor, you can remain in Service mode to streamline the setup process. If you’re a system owner, the monitoring mode is your best friend—enabling you to quickly check your LLS 4000’s performance while walking by. The app also limits the amount of code numbers you need to track, since the four variants2 of the LLS 4000 can be used in almost any refrigeration application. 1 R717 (Ammonia),R22,R507A,R134a,R404A,R407A,R410A,R513A,R1234ze(E),PAO (Oil),POE (Oil),Mineral (Oil) 2 LLS 4000 liquid level switch G 3/4” LLS 4000 SIL2 liquid level switch G 3/4” LLS 4000U liquid level switch NPT 3/4” LLS 4000U SIL2 liquid level switch NPT 3/4”
