The TEM universal controllers and system controllers with integrated heat management for one/two stage or modulating heat generators can be adjusted to the most various facility conditions thanks to their extensive basic functionality, such as the storage tank functions, solar and solid fuel possibilities, as well as their data bus communication.

In order to expand the heating circuit or to integrate further alternative energy sources, up to 8 TEM controllers can be linked via the eBUS – also wireless. Still the system remains simple: All controllers which are connected to the system are operated using one central remote control unit.
