The Bosch Rego 1000 is a control unit designed for managing heat pumps, providing information about their current status, and allowing users to adjust various settings. This user guide outlines its functions, usage, and maintenance aspects.
Function Description
The Rego 1000 serves as the central interface for controlling heat pump operations. It displays critical information such as temperatures (outdoor, room, hot water, flow), current time, and active operating symbols. Users can navigate through menus to view information, change settings, and manage various heat pump functions.
Key functions include:
- Room Temperature Control: Adjusting heating for different circuits, setting heat curves (Radiator or Underfloor), and managing room temperature programs. The heat curve dictates the flow temperature based on outdoor temperature, ensuring optimal comfort. The system allows for offsetting the curve and fine-tuning at specific outdoor temperatures. Room temperature influence can be set if a room sensor is present, allowing a K (°C) difference in room temperature to influence the flow line temperature.
- Hot Water Management: Selecting operating modes (Economy or Comfort), requesting extra hot water for a set duration and stop temperature, and scheduling hot water peaks for thermal elimination of bacteria (pasteurization) at approximately 65 °C. Hot water programs allow users to block hot water production during specific times.
- Holiday Function: Setting a lower or higher heating level and switching off hot water production during periods of absence. This function includes setting start and stop dates, desired room temperature, and the option to block hot water production.
- Energy Measurements: Displaying generated energy (kWh for heating and hot water) and consumption of electric additional heat (kWh for heating and hot water).
- Timers: Observing countdowns for time-dependent functions like extra hot water duration, alarm mode delay, operating time for heating at hot water demand, and compressor start delays.
- External Control: Managing functions activated by external inputs, such as room temperature settings or blocking compressor/additional heat.
- General Settings: Adjusting date, time, summer/winter time change-over, display contrast, and language.
- Alarm Management: Providing an information log, alarm log, and settings for alarm indication (buzzer signal, blocking times, control unit, and room sensor alarm lamp).
Important Technical Specifications
While specific numerical technical specifications are not extensively detailed in the provided text, the manual highlights several operational parameters and ranges:
- Heat Curve Adjustment: The heat curve can be adjusted for flow temperatures, with factory values specified for 20 °C outdoor temperature (22.0 °C) and -35 °C outdoor temperature (60.0 °C). The display shows the value at 0 °C outdoor temperature (factory value 35.7 °C).
- Room Temperature Range: Normal room temperature settings range from 10.0 °C to 35.0 °C.
- Hot Water Peak Temperature: Approximately 65 °C for thermal elimination of bacteria.
- Outdoor Temperature Limit for Change Over: Ranges from 5 °C to 35 °C, with a factory value of 18 °C.
- Extra Hot Water Stop Temperature: Ranges from 50.0 °C to 65.0 °C, with a factory value of 65.0 °C.
- Compressor Operating Time On/Off: Ranges from 10.0 (Comfort) to 30.0 (Economy), with a factory value of 20.0.
- Display Contrast: Adjustable from 20% to 100%, with a factory setting of 50%.
- Alarm Buzzer Interval: Adjustable from 1s to 3600s (60min), with a factory setting of 2s.
Usage Features
The Rego 1000 is designed for user-friendly interaction:
- Control Panel: Features an On/Off button, Mode button, Info button, Menu dial, Status lamp, Return button, and Menu button, all contributing to intuitive navigation.
- Menu Navigation: A menu dial allows users to navigate menus, adjust values, and save changes. A return button facilitates moving back to previous menu levels.
- Help Information: The menu display provides contextual help information, showing menu levels, drop-down lists, and indicators for further settings.
- Mode Button Functions: The mode button provides direct access to frequently used functions such as "Room temperature normal / Temperature increase/decrease," "Hot water mode," "Extra hot water duration," "Party," "Holiday," and "Disable cooling."
- Language Selection: The controller language can be changed by pressing the mode button for at least 5 seconds in the initial menu.
- Operating Symbols: Various symbols are displayed in the initial menu to indicate active functions or demands, such as compressor operation, heating, hot water, cooling, and external controls.
- Alarm Indication: The status lamp flashes red for unacknowledged alarms and lights red continuously for acknowledged alarms where the cause persists. An alarm buzzer sounds for a set interval, and alarm information is displayed in the alarm window and logged.
Maintenance Features
The manual emphasizes the importance of proper maintenance and provides information related to alarms and service:
- Qualified Personnel: Installation, commissioning, and repairs must only be carried out by qualified installers or personnel. Incorrect repairs can lead to serious risks and reduced savings.
- Original Spare Parts: Only original spare parts should be used.
- Annual Service: Service and maintenance should be performed annually by an authorized service representative.
- Alarm Categories: Alarms are categorized (A-H for alarms, I-J for warnings/information, K-M for warnings, Z for information) based on their type and seriousness. The alarm log provides details on occurred alarms and warnings.
- Alarm Reset Conditions: The manual details specific reset conditions for various alarms, such as temperature returning to permitted levels, communication being re-established, or manual acknowledgment.
- Troubleshooting: For persistent alarms or warnings, users are advised to contact the dealer, check heating system fuses, clean particle filters, and ensure thermostat valves are open.
- Information Log: The information log displays non-critical information from the heat pump, such as temporary stops or high flow temperatures, which do not necessarily indicate a fault but provide operational insights.
- Return to Factory Settings: Users can reset all customer settings to factory defaults, but settings made by the installer are not affected.
