The Buderus Logamatic BC10 is a base controller designed for operating standard functions of Buderus heating systems equipped with the Energy Management System (EMS). It allows direct control of the heating system at the boiler, offering various functions for users and heating contractors.
The BC10 base controller serves as the primary interface for managing the heating system. It enables users to switch the heating system ON and OFF, set the desired Domestic Hot Water (DHW) temperature, and define the maximum boiler water temperature for heating mode. The controller also provides a status display to monitor the system's current operating state and any potential faults or warnings.
For more advanced control and programming, the BC10 can be used in conjunction with various programming units, such as the RC3x or fascia. These units allow for convenient regulation of room and DHW temperatures, as well as the implementation of heating programs. When a programming unit is connected, certain settings on the BC10, like the maximum boiler water temperature, can be automatically adjusted based on the heating curve or other programmed parameters. If no programming unit is connected, the BC10 defaults to a maximum boiler water temperature of 90 °C.
The controller features a "Burner" LED that indicates the burner's status: ON when operational and heating water, and OFF when the desired temperature is reached or there is no heat demand. In case of a fault, the BC10's display will show relevant fault or warning codes, and users can attempt to reset the fault by pressing the "Reset" button. Locking errors require a manual reset, while blocking errors are automatically cleared once their cause is resolved.
The BC10 also supports a manual mode, which allows the heating system to operate independently of a programming unit. In this mode, the boiler water temperature is set directly using the right-hand rotary selector, and a decimal point on the display flashes to indicate manual operation. This mode is particularly useful in situations where a programming unit is not available or if there is a risk of frost and continuous operation is desired.
For contractors, the BC10 offers additional functionalities, including the ability to insert and remove programming units, start operation under partial load for tasks like adjusting a gas valve, and carry out a flue gas test. During a flue gas test, the heating system operates at a higher flow temperature for 30 minutes, and the decimal point on the display illuminates. Partial load operation allows the boiler to run at a reduced output, which is useful for specific maintenance tasks and is only possible with two-stage or modulating burners.
The controller also provides access to various parameters for contractors, such as limiting the heating load, setting the pump run-on time, determining DHW heating settings, and adjusting burner fan speed. These parameters allow for fine-tuning the heating system's performance during commissioning and service.
The BC10 is designed for straightforward operation. The ON/OFF switch allows for easy activation and deactivation of the entire heating system. Rotary selectors are used to set the DHW temperature and the maximum boiler water temperature for heating mode. The status display provides clear visual feedback on the boiler's current water temperature and any operational messages or error codes.
The "Reset" button is used to clear faults, and the "Chimney Sweep button" (also used for flue gas test and manual mode) allows access to specific operational modes for maintenance or independent control. The display provides various status indicators, including current operating pressure (if a pressure sensor is installed), operating status codes, and service interval messages.
When setting the DHW temperature, users can choose between "0" for no supply to radiators (exclusive DHW heating), "Eco" for an economy mode that heats DHW to 60 °C to reduce burner starts and save energy, or a specific temperature between 30-60 °C. The "Aut" setting allows the temperature to be controlled by a connected programming unit.
For maintenance, the BC10 facilitates several contractor-specific tasks. The programming unit can be easily inserted and removed, allowing for flexible system configuration. The flue gas test function simplifies the process of checking combustion efficiency.
The parameter setting mode allows contractors to adjust various operational aspects of the boiler, such as heating load limits, pump run-on times, and burner fan speeds. These adjustments are crucial for optimizing the system's performance and efficiency. The controller also displays service messages, such as "HAH" (service interval enabled) or "H00...H99" (service required), to alert contractors when maintenance is due. The service interval can be reset after maintenance is performed, ensuring that the system continues to track its operational hours or date for future service reminders.
Fault diagnosis is a key maintenance feature, with the display showing specific error codes (e.g., H7, 2E, A12) that help identify issues like low operating pressure or communication problems between modules. This allows contractors to quickly diagnose and address problems, ensuring the heating system operates reliably. The manual emphasizes the importance of contacting a heating contractor for recurring burner faults or persistent errors that cannot be reset.
