Questions and Answers
Q

Is the temperature controlled by an internal sensor or is it possible to use an external temperature sensor?

Q

USA NOTES: 1) This does not appear to have adaptors to US standard National Pipe Thread. 2) This is for so-called 2 pipe radiators. It is not for the single pipe system (the ones with the hissing air valve on one end of the radiator.

Powered by 4.5V (3x1.5V AA Batteries). Lifetime bof the atteries is depending on the frequency of usage and quality of the vatteries;, so this is not easy to answer in personal situations

It has aesthetic defects and the interior is dusty, which could have happened during manufacturing. Apart from that, I think I will find it useful.

The product is good but took much longer than agreed to arrive, and the packaging was damaged in transit because it did not receive any type of protection. They only came covered in plastic when at least they should have come in a cardboard box.
