I have a wall mounted A/C control box. It has a few whizbang
programming/scheduling features, which we do not use. We just set
temperature, because someone is always home anyway.
This control has two AA batteries inside and when the batteries run
out of juice, it just dies.
To me, this is very bad, since if it happens when we go on vacation,
in winter, the house is going to freeze, resulting in expensive
I am really livid that someone could design a control like this,
In any case, I am looking for a replacement that is designed for
reliability, and not for selling to suckers.
Any suggestions? I am personally totally open to the old style round
controls that just have a temp dial and heat/cool switch. I would
further prefer something that is smart enough not to need a heat/cool
switch and would maintain temp inside a band.
