Model 072000
Smart Digital Humidistat
Installation and Owner's Manual
The 072000 is a digital humidifier control
that can automatically adjust the indoor
humidity set point as the outside air
temperature changes. This intelligent
control will maintain accurate humidity
levels and a more comfortable indoor
environment.
The actual indoor relative humidity is
always displayed on the LCD screen. When
the
or
down
keys are pressed, the
humidity set point is displayed and can be
adjusted using the
up
and
down
arrow
keys.
An outdoor temperature sensor is included,
and must be connected in order to fully
utilize the features of the 072000. The
outdoor temperature sensor allows the
humidistat to automatically adjust the
humidity set point, to avoid condensation on
windows. It is also a convenient way to read
the outdoor air temperature at any time.

The outdoor sensor is not required to
use the Humidistat in the basic or
manual mode.
The 072000 operates on 24vac, and has
a set of isolated dry contacts for
activating the humidifier. Terminals are
also provided for the Outdoor air
Temperature Sensor. (Part

The 072000 can be installed on the
return air duct or, it can be installed on an
interior wall within the conditioned
space. EWC Controls recommends an
interior wall installation. NOTE: If the
return air duct is chosen as the location,
the HVAC fan should be set to run
continuously, in order to obtain an
accurate sampling of the actual living
space relative humidity condition.
