Skuttle Indoor Air Quality Products 2100, 2102 owner manual Humidistat Operating Instructions

Models 2002 and 2102. These models operate identically to the previous models, except that warm air is forced through the humidifier cabinet by a humidifier fan rather than by the furnace blower.

Humidistat Operating Instructions

Important Notes:

•Models 2000, 2001 and 2002 come with a standard humidistat. (See operating instructions, following.)

•Models 2100, 2101 and 2102 come with an electronic compensating humidistat, which operates automatically. See separate operating instructions entitled “Operating Instructions for Your Electronic Compensating Humidistat”.

Your new Model 2000, 2001 or 2002 flow-thru humidifier is controlled by a humidistat that is installed either on the cold air return of your

furnace or on an interior wall of your home. The recommended settings
for this control may seem illogical until you understand the principle
behind them....
As you can see from the Humidistat

mended setting goes down as the
outside temperature decreases—just
the opposite of how you operate your
furnace’s thermostat. To understand
the reason for this, think of what
happens to an ice-cold drink when
it’s outside on a hot summer day:
water (or condensation) forms on the
outside of the glass. Condensation
occurs because the hot summer air contains humidity, and the cold

surface of the glass cools the surrounding air. Once cooled, the air molecules become smaller and can no longer hold as much moisture. The result is that water droplets accumulate on the glass.
