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 Valve adapter ), 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.

When operating in unheated rooms, the internal storage will eventually be discharged. The unit then moves to 50% open position trying to recharge its storage. Operation in little or unheated rooms is not recommended. If the operation in unheated rooms cannot be avoided, the summer bit SB can be used. This means that the radio interval can be extended to 8 hours and the drive can also be addressed via radiomust be avoided since normal operation can not be guaranteed and a manual battery recharging is needed.
MVA008 is designed for low power operation. Therefore, all ReMan and ReCom operations are internally time limited and must be executed within less than 8 seconds. It is strongly recommended to execute ReMan only for initial teach over the air (Link Table) and device configuration (RESET) following its initial deployment.
