Humidistat for humidifier
By Brad - usenet poster
I am installing a humidifier on a force hot air system. I decided to
loacat the humidistat in the living area rather than the duct. Since
the humidistat determines relative humidity, it must accurately
measure room temperature. In the return duct in the basement I don't
believe it would read the temperature accurately.
Does anyone know if there is a significant gain in accuracy by
mounting the humidistat in the living area rather than the return
duct? Or should I just take the easy way and mount it in the return
duct.
Thanks.

The humidistat is from Honeywell and it is designed for either duct or
wall mounting. The problem with accuracy is the calibration. There is
a screw in all humidistats that is used for calibrating. I have an
accurate hygrometer so I would know if it was calibrated accuratly.
I also thought of using it to control the central a/c unit. I suspect
controlling humidity would be more energy efficient than just
maintaining a fixed temperature. The house would then be comfortable
at a higher temperture so long as the temperature isn't high into the
80s.

So long as it's designed for the job, a humidistat in the living area
will work fine. A humidistat designed for duct mounting may not be set
up to allow convection airflow through it as would be required for a
wall-mount unit. And a wall-mount unit may not be designed to tolerate
the dust of a duct-mount situation.
Probably the duct-mount unit would give a little tighter control, but
the difference wouldn't be great. The things aren't incredibly accurate
to begin with.

I just installed a new Kennmore 15 gal unit on my forced air system.
According to the instructions, the best place was to place the Humidistat on
the cold air supply. At theis point the humidistate could measure the room
temp as well as humidity and adjust accordinly.

I would imagine that the manufacturer realizes the difference, if any, and
would account for this in its design. So its possible that it reads the
temp and humidity TAKING INTO ACCOUNT its placement in the return.
