| _Honeywell H775A-E Electronic Remote Humidity Controllers | ||||||||||||
| The H775 Family of Electronic Remote Humidity Controllers provides humidity control for ducts, greenhouses, computer rooms, printing and photographic laboratories, and other applications where electronic accuracy, as well as remote sensing, is desired. | ||||||||||||
| ■ H775A provides on/off control with one humidity input and up to four relay output stages. ■ H775B provides staged on/off control with up to two humidity inputs and two relay output stages. ■ H775C provides floating output duct reset humidification control with two humidity sensor inputs and two auxiliary relay output stages, or staged on/off humidification and/or dehumidification control with up to two humidity sensor inputs and four relay output stages. ■ H775D provides modulating (4-20 mA) proportional plus integral (P+I) duct limit reset humidification control with two humidity sensor inputs and two auxiliary relay output stages. ■ H775E provides modulating (Series 90, electronic 135 ohm equivalent) P+I duct limit reset humidification control with two humidity sensor inputs and two auxiliary relay output stages. ■ Setpoint humidity range is 5 percent to 95 percent relative humidity (RH). ■ Uses C7600B or C7600C Humidity Sensors. | ■ Adjustable humidity (1 percent RH to 30 percent RH) switching differential. ■ Liquid crystal display (LCD) for sensed percent RH, mode and output status. ■ Keypad provides ease of programming and operation. ■ +/- 1 percent RH accuracy. ■ Stage(s) independently programmed for humidifying or dehumidifying. ■ Operates on 24 Vac input; 120/240 Vac inputs available. ■ Spdt relay outputs. ■ Adjustable Throttling Range of 1 to 15 percent (RH).
