Hi,
R.H. is function of temperature. Computer room is for the machine not
people. Too low humidity will cause static discharge and it is harmful
to the machines. Here in winter, most of time at home we keep it around
25% when it gets real cold(like -30C)

Here in SE Iowa our inside RH is currently 34% and outside it is 77%. In
fact, if you want to take a look just point your browser to
www.crsales.com/weather.htm and you will see my amateur weather station.
I don't look at the inside RH that often and quite honestly I was
surprised that it was that low.

50% is high to the Aprilaire folks-- I've been dicking around off
and on for 2 weeks wondering why mine isn't kicking on. One year old
humidifier-- new furnace install. Bought a new transformer. . .
tested where I had it hooked up. Finally read the manual again.
Max humidity is 45%. Mine is 47%.
*That's* why it has that 'test' setting.<g>

Hi,
Fresh air intake is two ways, one for combustion for the furnace and one
going into return air duct. Wonder if it is damper controlled and it is
operational in your case. Too air tight home definitely needs outside
fresh air in proper amount. My house is R2000 spec. We have damper
controlled outside air intake. Yet I am running a power humidifier in
the winter. I am in Calgary that is why. Our winter air is extremely dry.

In winter, I sometimes have to run a humidifier to get the humidity up to
50%.
Outside combustion air is quite common on high efficiency units but I'm not
sure it would lower the humidity level. Right now, the moist internal air
is being used and going out the stack and infiltration is replacing it with
the outside air. You may want to experiment a bit and crack a window open in
the room with the furnace and close it off from the rest of the house.
