AUBER INSTRUMENTS WWW.AUBERINS.COM 2018.06 P1/5 HD220 Dual Output Programmable Humidity Controller Version 1.2 (June, 2018) 1. Overview This is a dual-output humidity controller with 8 programmable steps. It contains one humidity sensor and two independent outputs. One output is for humidifier and the other is for dehumidifier. The humidity control can be programmed to vary with different time step setting. Up to 8 humidity-time steps covering 33 days can be programmed. It can be used for tobacco dehydration, sausage curing, etc. By using both humidifying and dehumidifying, the humidity ratio can be controlled at a specific value regardless of whether it is in dry or wet environments. This controller is a plug-n-play device. No extra wiring is needed for the humidifier or dehumidifier. Both humidifying and dehumidifying control modes contain simple on/off operation; they are similar to a mechanical humidistat but with much higher precision due to adjustable hysteresis band, precise sensor and digital read out. Different operation humidity ranges of the two outputs can be set separately. Once the dehumidifying range is set, the controller program will automatically limit the humidifying range to prevent both outputs from being turned on at the same time. This plug-n-play humidity controller is designed for high relative humidity (>85%) and condensing environments, where a slight drop in temperature may cause condensation and could damage other humidity sensors. This controller equipped with one of the most robust humidity sensors on the market. It can be fully recovered even immersed in water. Wireless network connection capability is available in HD220-W. User can access humidity data and parameter settings of the controller from their smart phones or tablets. AuberSmart App is available on both iOS and Android platform. For details, please check the supplementary manual. 2. Specifications Table 1.
