Setup & Network Connection (Instructions)
If you are setting up your iFresh Inline Fan (Model 2025) and the MarsPro Add-On Kit for the first time, please follow these steps for network connection:
-
Step 1 (Power Supply): Connect the inline fan to the power supply and plug the iConnect USB controller into the fan's designated USB port.
-
Step 2 (Connect Controller): Now connect the manual rotary knob controller to the RJ interface.
-
Step 3 (Activate Pairing Mode): Turn the knob continuously at least three times in a row, with each turn covering more than 50% of the scale. The fan is now in pairing mode.
-
Step 4 (Network Connection): Open the MarsPro App on your smartphone, add the new device, and follow the on-screen instructions to connect the fan to your Wi-Fi network. (Repeat these steps if you wish to change the Wi-Fi network later).
-
Step 5 (Activate Sensor): After successful network construction, disconnect the rotary knob controller from the RJ interface and plug in the temperature and humidity sensor instead. The setup is now complete.
Note: If the sensor does not appear correctly in the app after plugging it in, briefly disconnect the USB controller from the port and reconnect it.
