Safety and hazard information
Please note that electrotechnical work may only be carried out by qualified electricians or under their guidance and supervision. Observe any deviating country-specific electrical installation standards and regulations and seek advice from a local electrician.In addition, observe more current safety instructions and regulations for the products on the manufacturer's side or the product descriptions and installation instructions on the manufacturer's side.

Devices with a connected load of > 380V/400V require a heavy current connection and may only be connected by an approved electrical company. Devices with a power rating > 12kW require the approval of your grid operator (Germany, other countries may differ).

Function module EIB FM 446 – BUDERUS:

Areas of application and use

The primary area of application is aimed at single and multi-family houses, or smaller functional buildings. An EIB network already exists in these buildings and the individual rooms are equipped with an EIB individual room control, for example, but cannot communicate with the weather-compensated heating system. The module forms the interface for this. The FM446 module can also be used to remotely change over the operating mode of a heating circuit, provided this is done via an EIB sensor. This means that all heating circuits that are assigned to the controller can be switched over via the EIB in the operating mode, or can be subjected to a flow temperature adjustment using the EIB individual room controllers. If the heating system is equipped with service water preparation, this can also be adjusted remotely via EIB sensors in the operating mode. Temperature readings are in turn made available to the EIB devices for visualization via the EIB module.

Module equipment and influencing options

The main task of the module is to connect an individual room control to a weather-compensated heating control. In principle, this connection is realized via the maximum valve position of the radiator actuators in the system. The EIBA specification ''ObIS for Hot Water Heating'' serves as the basis for the development of the ''EIB page''. Each control device heating circuit can record and manage between 2 and 8 valve positions (EIS6) from different individual room controllers.

Since, according to the definition, one EIB module is permitted per controller and therefore only affects the heating circuits of the respective controller, a maximum of 7 heating circuits and 1 hot water circuit can be managed, depending on the controller. On the EIB side, the corresponding individual room controller can be assigned to ''its'' heating circuit via the EIB configuration. It is therefore possible to assign the respective individual room controllers to specific heating circuits. How this should happen can be defined by the EIB project planner or by the customer himself.

The heating circuits to be influenced can be preselected during commissioning via the parameter menu both in terms of the type of use and the extent of the influence via the EIB tool software (ETS2). Accordingly, only the data points and parameters of the previously selected heating circuits are visible. Within the Buderus MEC2 control unit, the appropriate setting must also be selected in the appropriate heating circuit menu ''Heating system''. This means that it is now possible to assign the respective individual room controllers to the heating circuits. However, this must be done in agreement by the EIB project planner on the EIB side, or by the heating engineer on the control device side during commissioning. If a setting that does not match on both sides is made, an error message occurs.

Furthermore, the FM 446 function module can also be used for remote adjustment/switching of the operating mode of the heating control via commercially available EIB devices.

Examples:

- An EIB communication object is made available by the FM 446 for hot water preparation for the ''One-time charge'' function via EIB switch, timer or motion detector. (Function ''one-off charge'' see documentation of your control device) - Switching of the operating mode of the hot water circuit and the circulation pump via correspondingly desired EIB sensors. - A heating circuit that is not equipped with an individual room control system can be switched over, for example using an EIB switch, EIB key switch in the front door, window contacts or motion detectors, via a communication object of the EIB module in its works council. - An operating mode switch for heat demand (e.g. swimming pool heat exchanger) can be integrated according to the above-mentioned principle via the heating circuit switchover. The mode of operation is switched over via 2 separate EIB data objects. One object switches between manual day or night mode, the second object between automatic mode with the timer function of the Buderus control unit or manual mode (day or night). If an adjustment is made on a Buderus device, the corresponding EIB device is updated to the current status via the new operating mode by means of feedback. Figure 4: Communication objects of the FM446 for a possible influencing of the hot water preparation via the EIB. A number of communication objects are also available for display. System data, a so-called collective error message and temperature values of the heating system can thus be displayed/visualized on EIB devices.
