Viconics 3% Humidistats VH7200 Series

Viconics 3% Humidistats


The Viconics VH7200 Series humidistats are designed for controlling humidification and dehumidification equipment in HVAC/BAS applications. The humidistat utilizes a PI time proportional control algorithm to accurately control relative humidity. The VH7200 Series features adjustable control setpoint, and the ability to set the maximum number of output cycles from 3 to 8 per hour. Units accept a remote outdoor air temperature sensor which can be used to reset the humidity set point-minimizing energy consumption and condensation on windows and building structures. The high limit protection prevents damage due to over-humidification.
