Details on electrical connections for various hydraulic systems, specifying terminal blocks for neutral and protective conductors. Mains voltage is 230VAC 50-60Hz, with low voltage connections in the left-hand terminal compartment. Specific terminals are designated for different components like heating circuit pumps and compressors. Sensor connections include options for RS485 interfaces.

Temperature sensor cables must be routed separately from mains voltage cables. The system uses Pt1000 sensors for accurate control, with cables extendable up to 30m. Proper placement is crucial for accuracy.

Requires a 2-strand twisted-pair cable, routed separately from mains voltage cables. A special circuit board is needed, and proper polarity must be ensured. Jumpers are required for the first and last units in a sequence.

The controller can display external error conditions via sensor input terminals. Short circuits can stop or shut down the heat pump, with errors displayed on the screen.

Features a display with text and graphics for easy operation. LEDs indicate different modes and errors. Four keys are used for input, with functions varying based on the situation. The menu structure allows navigation through settings and functions.

Includes options for displaying current temperature values, controlling system functions, setting operating times, and configuring parameters. A commissioning help feature guides initial setup, with manual configuration available.

Displays measurement values based on the selected program and connected sensors. The statistics menu provides function control and long-term monitoring, including operating hours and heat output.

Allows setting the current time, date, and operating times for heating circuits and hot water. Specific time ranges can be set for different days, with options for increased temperatures during low-rate periods.

• Low-Rate Time Period: Select based on usage patterns and utility low-rate periods.
• Domestic Hot Water (Menu 3.7): Set a time range for each day to charge the water tank to a higher temperature for Legionella protection. Default is off.
