NOTICE

The humidistat must be installed in accordance with
all local and national standards.

Installation, adjustments, alterations, service and
maintenance must be performed by a qualified ser­
vice technician.

Product Description 

The HC Digital Automatic Humidistat is a programmable
control for HCSteam residential humidifiers. While the HC
Digital Automatic Humidistat may be used for control of
other humidification or dehumidification appliances, its op­
erating modes are designed for modulating control of the
HCSteam electrode steam humidifiers.

When properly installed and configured, the HC Digital Au­
tomatic Humidistat will use information from the environ­
ment including Relative Humidity, Outdoor Temperature
and Home Construction to determine the Ideal Humidity
and the Optimum Humidifier Output.

The HC Digital Automatic Humidistat includes an Indoor
Temperature Sensor, Indoor Humidity Sensor and Control
Unit.  A separate Outdoor Sensor is supplied.
