evening. If we're cold, it gets cranked up but we usually don't.
Sweaters and sweats are the norm. The cats have coats on. ;-)
BTW, our frost line can go down beyond 7' (broken mains down that
That sucks! I had another nice day to work outside. It was a
glorious 62F here in NW Vermont. I think I got sunburnt though.
It's only supposed to be 50F tomorrow, but that's enough to finish
my stain and trim work.
It is time to get the wife's snow tires on though. ...or I'm going
to be driving her to work.
What matters is the temperature where you sit, compute, sleep, etc.
In my house, the thermostat is in a warm spot, and most of the places
I actually spend time are 2 - 3 degrees cooler than the setting.
So, if you want to deal with the actual temperature, check the
temperature where you actually do things, and set the thermostat up
or down to make your specific areas be the temperature you want.
You may want them at 68, or at 73, I don't care, but use a
thermometer, and set the thermostat to give the temp you want were
you spend time.
It's not that I think stupidity should be punishable by death.
I just think we should take the warning labels off of everything
and let the problem take care of itself.
Luckily it has been far warmer than usual here in the northeast. Daytime
temps have been low 50's to high 60's. Night temps are getting down
there but with day temps so high, the heat hardly runs and the place
states near 70F.
We took the expected latent heat load into account when trhe system
was sized. That still does not address what you set the thermostat and
humidistat to. Thw Weksler chart in a computer room is 2 concentric
rings when things are running right
In most places I've been, the rooms run at 21C (70F).
The RH is then adjusted to stop the room feeling too cold to
humans in cases where they have to work in there for long
periods. (A dry 21C with significant wind chill feels very
much colder than 21C.)

Maintaining RH at 50% is mostly to make the paper (cards in the olden
days) more machine friendly. At lower RH static is a problem and at
higher RH the paper stiffness suffers and it swells imparing feeding.
A production laser printer will be wadding up paper long before the
electronics start complaining. If the paper is too wet it will curl
when it goes through the fuser. A big printer shoving that paper out
at 3 pages a second will turn the stacker into something that looks
like a carnation.
I think people are far too concerned with the rest of the electronics.
DASD in a data cernter is just the same drives you have in your PC
piled in a big box these days and the processors are not that much
different than your PC. It is certainly a similar packaging. I have
PCs running in totally unconditioned space in SW Florida with no
problems. In fact one survived a fire. 3 are running in vehicles that
see 130-140F in the day time and wide swings in RH.
IBM started saying in the 80s that if the people could handle the
environment the computer could. 4300 mainframes and AS/400 mid range
were "office environment" machines. It was really the big paper
pushers that needed conditioned space.
