# ⚙️ Factory Settings Reset
Factory Settings Reset (Hard Reset) allows to reset device to factory settings.
To enable Factory Settings Reset:
- Turn off the device.
- Press and hold the
Start/Stopbutton and turn on the device.
- Hold the button. LEDs start blinking one after another.
- Release the button. All LEDs will blink once.
- Factory Settings Reset started. Device will be automatically rebooted. All LEDs blink trice.
Start/Stop button have not been released Dryer will be in Stand-by.
# 📈 Remote Monitoring and Control
Dryer 2.0 comes with pre-installed UCM (Universal Communication Module) that allows users to monitor the device. Over-the-air updates ensure that the latest protocols and security fixes are supported.
Pre-installed UCM connects to the Enapter Gateway and send performance and error data to the Enapter Cloud. The data is stored in a time series database which displays it real-time on customizable dashboards.
Enapter's mobile application ensures quick and easy installation of any energy system. Users can manage the dryer via the mobile app and will receive push notifications to warn of energy system issues.
# Network Requirements
# WI-Fi Requirements
802.11a/b/g/n (2.4 GHz only)
802.12 WEP, WPA, WPA2 Personal (Pre-shared key)
Wi-Fi client isolation must be disabled
No captive portal or WPA2 Enterprise supported.
General Wi-Fi Note
The Enapter Cloud connection based on wireless communication and therefore the functionality can be affected with distance in between devices, obstructions between the devices and interference. Communication module inside the dryer works in station mode and utilizes Wi-Fi channel set in your infrastructure Wi-Fi router for used SSID. You are responsible to select the correct channel according to the local radio regulations.
# Connecting your Dryer 2.0 to Wi-Fi
To connect the dryer to wireless networks, follow the steps in the iOS or Android Mobile Application guides below. Please note, the QR-code or preinstalled UCM's ID and PIN are required when connecting to Wi-Fi as well as credentials for the 2,4 GHz Wi-Fi network.
During connection to Wi-Fi network the QR-code or preinstalled UCM's ID and PIN needed. The location for both of them is shown on pictures below.
# Dryer 2.0 Configuration Options
Dryer 2.0 Configuration Options is valid only for dryers with firmware before 3.0.0.
The following options can be configured at https://cloud.enapter.com (opens new window):
InPres Min- inlet pressure minimum
InPres Max- inlet pressure maximum
OutPres Min- outlet pressure minimum
OutPres Max- outlet pressure maximum
This allows you to set the exact pressure ranges to start and stop the drying processes.
| ||Dryer starts|
