Really! Just for reference - I designed and wrote the software for the
very first micro-based home central heating system controller. It did
all of the temperature sensing and timing in the one unit, it included
variable timed temperatures as well as the basic on off and frost
protection. This was long before the Internet appeared and in the very
early days of home computers.

The fact that what I suggested works and continues to work, is cheap to
implement sort of proves that I do know what I am doing. Your comments
suggest you are a troll.
