TAC develops continuously new products for energy savings. Building automation solutions play an important role to get an insight into and be able to manage the energy consumption, so as to eventually save.
The TAC Xenta 121-FC/230 sun controllers from Schneider Electric are intended to control and program heating and air conditioning. They are based on the open communication standard LonMark®, so that the controllers can be used stand-alone or within a LonWorks® network. In addition, these controllers enable the integration of other systems, independently of the manufacturer.
The TAC Xenta 121-FC/230 controllers comply with the EU directive for better energy performance that has been released by the European testing body eu.bac (European Building Automation and Controls Association).
Briefly, with the TAC Xenta 121-FC/230 zonal controllers you increment the energy performance of your building. We make the most of your energy!
