# 🔌 Communication Interface: Modbus TCP
In case you want to monitor and manage your device with the Modbus TCP interface check out the latest registers map guide and use cases:
Warning
Modbus TCP works over an insecure connection and was designed for usage in isolated Local Area Networks for Operation, Administration and Management. Please take into account that connection to public networks such as the Internet is not recommended for security reasons.
# 🕸️ Communication Interface: Dryer Control Network
The Dryer Control Network (DCN) function is Smart Control for Dryer and Water Tank (optional) using M2M (opens new window) communication between Electrolysers, Dryer and Water Tank via a wireless MESH network. This type of control allows to lower down energy consumption, reduce the possibility of operating errors and increase the safety.
For more information please check the Dryer Control Network Documentation (opens new window).

# 📈 Remote Monitoring and Control
# Introduction
Dryer 4.1 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 sends performance and error data to the Enapter Cloud. The data is stored in a time series database which displays it in 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
Note
No captive portal or WPA2 Enterprise supported.
General Wi-Fi Note
The Enapter Cloud connection is based on wireless communication and therefore the functionality can be affected by distance 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 your SSID. You are responsible for selecting the correct channel according to the local radio regulations.
# Connecting your Dryer 4.1 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.
# 🔧 Operation Functions
# Wi-Fi Button
Using this button you can switch the UCM OFF/ON.
This can be needed if:
- You do not want to use connection to Enapter Cloud (opens new window).
- You want to protect the Dryer from remote activation when maintenance is in progress.
Warning
Be sure that UCM switched ON while you enabling or removing Dryer Control Network (opens new window).
# Factory Settings Reset
Factory Settings Reset (Hard Reset) allows you to reset the 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 three times.
If the Start/Stop button has not been released, the Dryer will be in Stand-by.

# Start/Stop Pressure Adjustments
This feature allows you to fine-tune the automatic start/stop pressure thresholds.
These parameters can be set using Electrolyser Modbus TCP Interface (opens new window), Enapter Web GUI (opens new window) or Enapter Cloud (opens new window).
# Adjustable Parameters
out_pressure_threshold_min
- Description: Lower bound at which the Dryer will automatically restart from standby.
- Range: 5 – 33 barg
out_pressure_threshold_max
- Description: Upper bound at which the Dryer will stop running and enter standby.
- Range: 10 – 35 barg
Note
- Avoid setting
out_pressure_threshold_minandout_pressure_threshold_maxtoo close together, as this can cause frequent cycling. - Monitor the daily cycle count via the diagnostic system after any change.
Warning
Changing the restart pressure can lead to intense cycling. The Customer takes full responsibility when changing the pressure values from the factory defaults.
# Device Diagnostics
Operational Period is defined as the total time the dryer spent in active states, excluding the following states:
- "waiting for pressure"
- "max pressure standby"
- "stop by user"
Using Enapter Cloud (opens new window) it is possible to execute the command Get Average Operational Period in the Diagnostics tab of the Commands section at the dryer's page.
| Parameter | Description |
|---|---|
last_average_runs_count | Number of the most recent runs used to calculate last_average_operation_time (should always be 20 unless fewer than 20 runs exist). |
last_average_operation_time | Average operational period over the last 20 runs. |
total_average_operation_time | Average operational period over the entire lifetime of the dryer. |
