Hi,
I have a spare 868MHz thermostat which was part of a set with one control unit and two actors. It still works, but in my home I only need one actor. My current actor works since years so want to feel the thrill to have no more spare for it…

It was part of this kind of set: https://www.elv.de/Funk-Heizkörperthermostat-System-Funk-Ventilantrieb-FHT-8V/x.aspx/cid_726/detail_34682

I really have no idea how much I can expect for it… My offer 19€ incl. shipment within Germany, but I can ship for sure in other countries with the appropriate surcharge.
I prefer PayPal, but classic giro transfer is okay as well.
