New Set /4 MicroPelt MVA004 ITRV Self-Powered Radiator Valve Actuators, HCV0104

Description

3839SB1C.2.83
New MicroPelt Self-Powered Radiator Valve Actuator Sets, Actuator Part Number HCV0104, with Controller Circuit Boards in Wall Box.  Each Set Includes (3) Bedroom Actuators, (1) Living Room Actuator, and (1) Controller Board in Standard Electric Wall Box (Everything Shown in Picture #1).  You may bid / buy any number of sets, up to the total quantity available above. Presumably, you will also need a thermostat (not included) to interface with the control board. Remember, if you don't see it, it's not included.
These were purchased at a lost freight liquidation earlier this year, and they were brand new in the original factory boxes.  Pretty high tech stuff, and we don't even pretend to know anything about them.  If you rub the little ring in front (picture #9) using a circular motion, the actuators will hum softly and light up momentarily.  Reminds me of a girl I used to know...
Note
: The manufacturer's datasheet (below) shows the control frequency as "868MHz."  The actuator labels are marked "902MHz."  A customer messaged us and said the 902 MHz frequency is for the US market.  Please verify compatibility before purchase.
According to the manufacturer
:
Functions
• The thermogenerator converts temperature difference between radiator intake and ambient air into electricity.
• Excess energy generated in winter enables continuous operation during transition periods and summer.
• Maintenance-free operation on 365 days per year.
• Exact valve position guarantees precise room temperature.
• Communicates bi-directional with EnOcean radio EEP A5-20-01.
• Configurable through remote management/commissioning (ReMan/ReCom).
• Feedback information to visualize valve status and internal energy-management.
