The text below indicates if the unit is actively Working or in Standby (target achieved). * **Fan Speed Selection:** Tap the options on the right side to set the operating intensity: -Quiet: Lower fan speed for reduced noise operation. -Standard: Higher fan speed for maximum efficiency. 3.Target Settings (Cooling, Heating \& Dry Modes) Tap the bottom panel ("Control By...​") to set your ideal environmental target. Drag the slider to set your desired value (e.g., **Target Temperature** at 80°F or **Target Humidity** at 50%). The air conditioner will automatically activate when the environment deviates from your setting and enter Standby mode once the target is reached. 4.Power Controls Tap the green Power button in the top right corner to instantly turn the device ON or OFF across all operating modes. ### Heater Settings Page {#_heater_settings_page} ![a6ac600288c3ff2c6d712374b39c0067](https://image.next.vivosun.com/asset/width-1266/picture/a6ac600288c3ff2c6d712374b39c0067.png) This interface allows you to add warmth to your environment to maintain ideal temperature or VPD conditions. 1.Current Status \& Heat Level * **Current Reading:** The large central number displays the real-time temperature of your environment. The text below it indicates if the unit is actively Working (heating) or in standby. * **Power Level Limit:** The dashed green ring around the central dial displays your active heating limit. By dragging the marker along the ring, you can set the maximum heat output intensity from MAX L1 to MAX L5. This determines how much power the device is allowed to use to reach your target. 2.Target Settings Tap the bottom panel("Control By...​") to open the detailed target setup menu. Use the top tabs to choose your preferred control metric: * **Target Temperature:** Drag the slider to set a straightforward heat target (e.g., 77°F). The heater will automatically activate when the environment is colder than this value and stop once the target is reached. * **Target VPD:** Drag the top slider to set your desired VPD value (e.g., 1.2kPa). In this mode, you must also define a safety **Temperature Range**(e.g., Min 66°F to Max 85°F). The heater operates based on these three zones: **-Below Min Temp:** The heater runs continuously to quickly raise the temperature into the active range. **-Within Range (Min to Max):** True VPD control zone. The heater intelligently modulates to reach and accurately maintain your Target VPD. **-Above Max Temp:** The heater automatically stops working entirely, regardless of the current VPD level, to prevent accidental overheating. 3.Power Controls Tap the green **Power button** in the top right corner to instantly turn the device ON or OFF. ### Auto Mode {#_auto_mode} Settings for the thresholds between the duct fan's standby and active zones can be adjusted using the GrowHub Controller or the Vivosun App. In the Vivosun App, you can also set the duct fan's behavior during standby mode, choosing either to keep it OFF or run it at a minimum speed. When temperature or humidity reaches a specified threshold, the duct fan will turn ON or increase its speed. The further the environment deviates from the threshold, the higher the fan speed will become. The inside temperature or humidity reading will flash if the values rise above or drop below the set levels. ![70223826d0880d1eeadcf74dbd753753](https://image.next.vivosun.com/asset/width-3093/picture/70223826d0880d1eeadcf74dbd753753.png) The alarm icon ![e7c6efef49878710dcdcf324d4364ebe](https://image.next.vivosun.com/asset/width-93/picture/e7c6efef49878710dcdcf324d4364ebe.png) will flash if the inside temperature or humidity exceeds the set range or if the duct fan remains in working mode for more than 1 hour. ### Auto Mode ---Temperature example {#_auto_mode_temperature_example} ![674a354f0519c8435d77739d1897b5a5](https://image.next.vivosun.com/asset/width-16/picture/674a354f0519c8435d77739d1897b5a5.png) `Duct Fan Standby Zone(Standby status (OFF or min. speed))` ![4b9e4b6b2a8c68733dd59df725702e24](https://image.next.vivosun.com/asset/width-16/picture/4b9e4b6b2a8c68733dd59df725702e24.png) `Duct Fan Working Zone(Duct fan ON / speed up)` ![2397531b06793035c96c8b26bc9cc12e](https://image.next.vivosun.com/asset/width-6241/picture/2397531b06793035c96c8b26bc9cc12e.png) `*The horizontal axis represents Temperature (°F)` `① Low Temp.

When the temperature reaches a set threshold, the duct fan will turn on or increase its speed. The further the temperature exceeds the threshold, the higher the fan speed will become. **Note:** For precise VPD control, use HVAC devices (AeroLush Air Conditioner, AeroStream Humidifier, AeroDrain Dehumidifier, AeroFlux Heater) together with the system. The duct fan alone can only help regulate VPD by exchanging air between the grow tent and the external environment to adjust temperature and humidity. ### Advanced Auto Mode {#_advanced_auto_mode} Use the Vivosun app to switch the duct fan to Advanced Auto Mode, where the system also considers the temperature and humidity outside your grow space when controlling the fan. In this mode, you can set minimum and maximum temperature and humidity thresholds. If the outside conditions are worse than inside, the duct fan will not increase speed---even if the internal temperature or humidity exceeds your set range. The alarm icon will flash to notify you that the external environment is unsuitable. To enable Advanced Auto Mode, go to the Vivosun app: Settings \> Additional Settings \> Duct Fan Auto Trigger Mode.
