Motorised Radiator Valve Harvests Thermal Energy for Battery Free Operation
Smart valve with multiple features – The Micropelt thermogenerator chip MPG-D65x converts the temperature difference between the radiator and the ambient room temperature into electrical energy. The thermo voltage is stabilized, managed and stored by our efficient power management circuitry, which drives the actuator as well as the wireless communication.
The energy-friendly actuator design including gear and motor as well as the ultra-low power electronics keep the energy consumption at a minimum. Therefore the iTRV delivers multiple adjustments per day and can communicate regularly with the room controller.
The smart valve is equipped with a rechargeable storage element to accumulate surplus energy for the transition months in spring and fall. In summer the iTRV automatically enters sleep mode but wakes up again routinely as soon as the heating is turned back on.
