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.
