Have you got closed down TRVs on the rads if 22 C in the room?
The Nest is supplied at 12 vdc from the Heatlink although the book says that it is 5 v. They will also work from the 5 v from a USB connection.
I did not know that they would send the signal to the Heatlink via the 12 vdc connection rather than use the wireless. Sensible thing to do. Do both the earlier and latest do that?
Always prefer maker's advice on connections. But I can test that on my early one at home!
