Communicating
Humidistat Series
FEATURES
● PI time proportioning algorithm...increased comfort, accuracy, and
energy savings
● Binary input...adds functionality
● Unique local configuration utility...minimizes parameter tampering
● Lockable keypad...tamper proof, no need for thermostat guards
● EEPROM memory...no loss of program
● Optional remote humidity sensors...increased flexibility and functionality
● Embedded humidification sequence (0-10VDC output) and dehumidification
sequence (dry contact)...simplifies installation and reduces costs
● Internal RH sensor embedded...eliminates components
● Proportional high limit override (VH7270 models only)...prevents costly damage
due to over-humidification
● Humidity setpoint reset based on outdoor temperature (VH7270 models only)...
saves energy and prevents window condensation in colder climates
● Sensor failure protection...prevents water damage

DESCRIPTION
The VH7200 humidity controller family features a complete embedded humidity
control solution with an intuitive backlit LCD display that walks the installer through
the configuration steps, making the process extremely simple. Accurate relative
humidity control is achieved via the product’s unique PI time proportional control
algorithm, which virtually eliminates humidity offset associated with traditional,
differential-based humidity controllers.
All models contain a user-controlled binary input, which monitors an electrode
humidifier canister service status or may be used as a general purpose service
indicator. Models are available with more advanced features such as discharge
humidity, proportional high limit, and indoor humidity setpoint reset based upon
outdoor air temperature.
APPLICATIONS
