Quick guide from the manual
This manual provides essential operating instructions for the Viessmann Vitocal 150-A and 151-A air/water heat pumps. It covers system control via the 7-inch color touch display and the ViCare app. Key safety warnings include the use of flammable R290 refrigerant, requiring a defined safety zone around the outdoor unit.
Device Description
The system consists of an indoor unit and an outdoor unit. It provides space heating, cooling, and domestic hot water preparation. It can be integrated into a system with other heat sources (hybrid operation) or cascaded with up to 5 heat pumps.
Operation and Settings
The system is operated via the touch display or the ViCare app. The home screen provides access to main menus for heating/cooling, hot water, and system status. Users can set time programs for heating, cooling, and hot water to optimize comfort and energy efficiency.
Safety
The outdoor unit contains flammable R290 refrigerant. A safety zone must be maintained around the outdoor unit, free of ignition sources, openings, or electrical installations. Do not touch the heat exchanger fins, as they can be sharp or reach extreme temperatures.
Maintenance
Regular inspection and maintenance by a qualified professional are required by law to ensure safe and efficient operation. The user should keep the display clean using a microfiber cloth and avoid using harsh chemicals on the unit's casing.
Troubleshooting
If the system displays a warning or fault, check the status menu for details. For common issues like rooms being too cold or no hot water, verify the system is switched on, check the time programs, and ensure the heat pump is not in a restricted mode (e.g., EVU-Sperre).
Technical Data and Compatibility
The system is designed for domestic use. It supports integration with photovoltaics (Smart Grid) and can be managed via the ViCare app if a WLAN connection is established.
