This Fan-Tastic Vent roof has a built-in 12V fan that uses a thermostat to help maintain an even temperature inside your RV, camper, or enclosed trailer. The fan can also be controlled manually with the built-in hand knob or with the controls on the vent housing. A rain sensor is included as well to signal the dome to close and the fan to shut off when it gets wet.

Air out your RV after cooking or just draw in some fresh air while you sleep. This remote controls the vent's thermostat as well as its manual and automatic speeds. You can control the direction of airflow - in or out - with the push of a button. Operate the remote control in your RV or place it in the included wall cradle so you will always know exactly where it is.

This variable-speed ceiling fan operates in 2 modes: manual and automatic. An on/off button automatically lifts the dome and activates the fan. To use the manual mode, press the arrow buttons on the left side of the remote or turn the knob on the vent housing to increase or decrease the fan speed.

The manual speeds are listed on the remote from 10 percent to 100 percent. As you cycle through the speeds with the arrow buttons, an LED light next to the selected setting will light up. As you cycle, you may notice that the LEDs for 2 settings will be simultaneously lit. This means that the selected speed is the average of both of those settings.

To switch from the manual to the automatic, thermostat-controlled mode, press one of the temperature arrow buttons on the right side of the remote. When using the automatic mode, you can preset the vent to maintain a desired temperature inside your RV. The temperatures are listed from 60 F to 90 F. As you cycle through the temperatures with the arrow buttons, an LED light next to the selected temperature will light up. Again, when 2 temperature settings are simultaneously lit, the selected temperature is the average.

The fan's internal thermostat will sense the actual room temperature, and the fan will run until the preset temperature is achieved. When the temperature rises above the preset temperature, the fan will automatically kick on again. So when you go out, you don't have to waste energy by leaving the vent running at full blast just to ensure that your RV is cool when you return. And because the fan will activate anytime that the preset temperature is reached, you can set up the system to ensure that your pets remain comfortable while you're out.

A moisture sensor ensures that the dome will close when rain or snow hits. So you can leave the vent running or preset to run at a certain temperature, even if the forecast calls for rain. When the sensor gets wet, it signals the dome to close. With the dome closed, the fan blades will stop running. When the sensor dries, the dome will re-open and the fan blades will resume operation. To keep the sensor from activating in rain, snow, or humid and dewy conditions, simply add a vent cover (sold separately) to block moisture. To disable the rain sensor, hold the up/down button on the remote for 3 seconds.

This vent requires of 14 1/4" X 14 1/4" opening in your trailer's roof and ceiling. To replace an old vent, install this vent into the existing opening. If your roof does not already have a vent, you will need to mark and cut an opening between roof joists to install this unit. The 2-wire design makes it easy to have your vent hooked up and ready for use. This fan does not come with installation components, see below for installation kit options.
