Weishaupt Energy Manager (WEM) is a free Android application developed by Max Weishaupt GmbH. It is a useful tool for controlling your Weishaupt gas condensing unit type WTC-B heating system. The WEM app allows you to access your heating system quickly and easily via the WEM-Portal. You can adjust the room and hot water temperature, heating times, and operating mode.

One of the most significant features of the WEM app is that it displays the current external temperature and provides yield statistics for heating, hot water, and total by day, week, and month. Moreover, it allows you to set party/heating pause and holidays. If you have a WEM-EM SOL, you can also see the current collector temperature, current capacity, and yield statistics for the day, week, and month.
