# Autoterm 2D & 4D

#### How to Integrate Autoterm 2D/4D with VAN PI System

**Step-by-Step Guide**

1. **Remove the Standard Control Panel**:
   * First, remove the standard control panel from your Autoterm 2D heater.

2. **Connect the USB-Autoterm Cable**:
   * Attach the USB-Autoterm cable to the same connector where the control panel was previously connected.

3. **Connect to VAN PI System**:
   * Plug the other end of the USB-Autoterm cable into a free USB port on your VAN PI System.

4. **Configure the Web Interface**:
   * Access the web interface of your VAN PI System.
   * Navigate to the "System" section.
   * Set the appropriate port to "Autoterm 2D"  or "4D"

5. **Set Up the Inside Temperature Sensor**:
   * In the "System" section, configure the inside temperature sensor. This sensor will be used for temperature regulation. -> If no sensor is connected only the Power Mode is working. 

6. **Operating Modes**:
   * **Temperature Mode**:
     * Triggered by "start temp mode".
     * The heater maintains the set temperature.
   * **Power Mode**:
     * Controlled via a slider or started with the "Start" Button
     * Allows manual adjustment of heating power.
   * **Ventilation Mode**:
     * The heater functions only to circulate air without heating.

7. **Additional Features**:

* **Timer Function**:
  * You can set a timer to schedule the heater to turn on or off at specific times.
* **Runtime Function**:
  * Allows you to set a specific runtime for the heater, after which it will automatically shut off.

8. **Information Displayed**:

* **Voltage**:
  * Displays the voltage supplied to the heater, which might be slightly lower than the system voltage due to cable loss.
* **Fuel Pump**:
  * Shows the frequency of the diesel pump in Hz.
* **Fan**:
  * Indicates the fan motor's RPM (revolutions per minute).
* **Heater Temperature**:
  * Displays the current heat exchanger temperature.
* Note that some of these information parameters may not be available on the **4D** model.

By following these steps, you can effectively integrate and manage your Autoterm 2D heater using the VAN PI System, taking advantage of its various modes for optimal comfort and efficiency.
