• NOTE indicates that minor damage to property may occur.
• CAUTION indicates possible minor to medium personal injury.
• WARNING indicates possible severe personal injury.
• DANGER indicates that severe personal injury may occur.
Important information
Important information that presents no risk to people or property is indicated with this symbol. It is separated by horizontal lines above and below the text.

WARNING: Only transformers with following specification are permitted:
6 V AC; 400 mA. The transformer is not part of the product! Please take care to use a reliable product which meets our requirements shown above. Do not mount the transformer internally!
Buderus does not accept responsibility for systems which contravene the Installation instruction or addition documentation in scope of delivery.
The transformer must be mounted in a separate enclosure which is rated for this purpose.

1.2 Safety instructions

Installation and commissioning
The Logamatic LON-Gateway interface module has been designed and built in accordance with currently recognized standards and safety requirements. However, dangers or property damage may arise if it is used improperly.
B Observe these instructions to ensure satisfactory operation. B The appliance may only be installed and started up by a trained installer. B All changes and adjustments made via superior control systems must meet the heating system
requirements.
Risk of death from electric shock
B The power supply must be connected by a qualified electrician. B The terminal diagram must be followed. B Before opening the appliance, isolate all poles of the mains power supply and secure against
unintentional reconnection.
B Never install this appliance in wet rooms. B Ensure that a circuit breaker is available to disconnect all poles from the mains power supply.
If there is no circuit breaker, you will need to install one.
Risk of damage from operator error
Operator errors can cause injury and damage to property.
B Ensure that children never operate this appliance unsupervised or play with it. B Ensure that only individuals who can operate this appliance correctly have access to it.
Device damage from electrostatic discharge (ESD)
B Before unpacking the module, touch a radiator or a grounded metal water pipe to discharge any
electrostatic charge in your body.
Damage from incorrect spare parts
B Only use original Buderus spare parts. Damage caused by the use of spare parts not supplied
by Buderus are excluded from the Buderus warranty.

2.1 Correct use

The Logamatic LON-Gateway may only be used to connect Buderus boilers with control panel from the Buderus Logamatic 4000 control series to superior control and/or building control systems via LON-BUS.

2.2 Disposal

2.3 Product description

The Logamatic LON-Gateway is incorporated into a LON network via a twisted pair cable (twisted 2-wire line). The twisted pair cable is protected against reverse polarity.
Defined data of the Buderus control panel is implemented with the Logamatic LON-Gateway interface on standard network variable types (SNVTs) for the LON data bus. The communication includes forwarding of error messages, operating messages, and actual values, as well as changing of set points and operating modes for boilers and consumers.

2.5 Specified communication objects

With the LON-Gateway, selected data from up to four Logamatic 4000 control panels can be exchanged via LON data bus with third-party control systems.
In addition to the communication objects for the first boilers, which are a component of the control panel, additional functions in the form of modules for multi-boiler systems, heating zones, DHW, and solar can be added.
If heating zones are served via LON, no other remote controls, e.g. Buderus remote control BFU, may be connected to this heating zone.

2.6 Logamatic LON-Gateway firmware

2.6.1 Firmware when delivered

When delivered, the firmware version LON_Flasher_2B_00 is preinstalled. This version is for a heating system with floor-standing boilers with Logamatic 4321. If you need another firmware variant (e.g. LON_Flasher_4B_00) for your installation, it is easy to update the firmware. (see procedure for updating firmware)
The firmware version of your LON-Gateway is displayed via the Logamatic ECO-SOFT 4000/EMS service software (Start communication -> Select COM port settings -> Direct connection). You can find the correct COM port under: Windows XP from the device manager (Control panel -> System -> Hardware -> Device manager -> COM port). Procedure for Windows Visa and Windows 7: Control panel -> Hardware and Sound ­> Device manager -> COM port.

2.6.2 Procedure for updating firmware

First the LON-Gateway must be connected to the power supply and connected on-site to your computer via the RS232 interface or USB converter.
B Obtain the desired firmware from Buderus and, start the LONFlasher*******.exe. B Select the COM port. B Start the update with the Flash button.
A display informs you about the current progress. The update is only complete when a message "...successful!" appears.
B When a message "...successful!" appears, confirm with OK.
The update is complete.
After the successful update, disconnect the LON-Gateway from the line voltage for approx. 2 minutes to perform a reset. This completes the firmware update.
