In-Car Wired Futura® Programmable Control Unit

Control your WarmUp system

Control your DEFA system from inside the cabin

Art. nr: 443101


A complimentary component in the WarmUp Assembly, it is available either with an in-cabin control unit (Futura) or with a Bluetooth (Smartphone) connectivity. It allows you to separately control the heating system from the charging function and to program your heating system so your vehicle is ready when you need it, without wasting electricity or using fuel. The Bluetooth solution offers the convenience of connecting your smartphone device at no additional cost (no subscription is required). Above all it alerts you if you have forgotten to unplug the cable before you start driving (smartphone must be paired to the hub).
