Humidistat | 0-10V Hum | Switched Dehum | Prprtnl High Lim | OutRst
0-10V Humidification, On/Off Dehumidification, Proportional High Limit, Outdoor Air Temp ResetDescription
The VH7200 humidity controller family is specifically designed for control of humidification and dehumidification equipment such as steam header direct injection, desiccant wheel, or stand-alone humidification / dehumidification equipment. The product 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 due to 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 binary input, which can be set by the user to monitor an electrode humidifier canister service status or may be used as a general purpose service indicator. Models are available which contain more advanced features such as discharge humidity proportional high limit, and indoor humidity setpoint reset based upon outdoor air temperature to conserve energy and eliminate condensation on windows and structure.
