Just realized that this is the same product as the
Becket heatmanager
My questions are still relevant though.
I don't understand if it is getting heat load feedback by measuring the return water temperature---it doesn't quite say that.
And if it can expand the deadband, why doesn't it just lower the max temp instead? (I realize this would not reduce short-cycling.)
