Allows for remote access and programming for Lochinvar boilers, great functionality and ease of use! I recommend for all engineers and contractors who are interested in, or currently using, Lochinvar Condensing Boilers.

Not 100% Ready for IOS 11.2.5


I installed the software on a iPhone X running iOS 11.2.5. When launched, the software locks my phone into landscape view and won’t release it to escape from the program. I had to shut down my phone. Many attempts to register my unit failed. Unrelated to the software, the barcode and QR Code that you are supposed to scan are not real accessible, making the process difficult. I’m hoping there’s an update because it is a good concept.

Great concept; info never updates


It got installed and I got registered. Got the board connected but there was poor wireless signal. (Replaced cable modem.) If you can manage wired Ethernet, I strongly recommend that because the app does not report to you if the unit goes offline.
My biggest issue is that the board and the app are not communicating. So occasionally, I think maybe when the boiler is power cycled, the board starts up and the data get communicated to the phone. Otherwise not. This might be iphone/iPad specific; I don't know.
The other thing is a design issue- many of the values shown on the screens are irrelevant, depending on your system configuration. It is a lot of work to remember which parts of the display are relevant.
