This document defines the properties of Micropelt’s battery free thermostatic radiator valve MVA008. The unit is directly mounted onto radiator valve bodies (M30x1,5 thread or Ventiladapter ), where it controls the room temperature, based on signals of a central controller. It is radio-controlled and powered by energy harvesting, so it neither requires any cabling work nor does it consume batteries. It is designed for maintenance-free operation. The wireless design makes the unit ideal for retrofit installation and cost-sensitive projects, where cabling cost is prohibitive. A room controller can be used to conveniently set time programs that set the room temperature to different values at different times of the day. By lowering the room temperature in times of absence, heating costs can be saved without any loss of comfort. Reducing the room temperature by just a few ° C also leads to cost savings.
