I have this transmission unit due to the loss of the old unit (renovation of the external façade / she was gone ...) bought. Before I have to figure out if there is a similar device at all. My model BAR112 (receiver) has a few years under their belt and reluctantly I wanted to give it up. So I discovered a perfect review of the THR 128 and then I ordered the station which has the advantage of a display (was not available in the old device). Battery inside, turned on and no problem I could receive the outer temperature. Noticing would be that Amazon has once again reacted promptly and super - Thank you also on this path!
