However, you can individually set and adapt theoperating modes and functions afterwards.You will find all the information on operating modes,auxiliary and special functions in Chapter 8, "Controlsystem".The heat pump is equipped with numerous automaticauxiliary functions to ensure trouble-free operation(see also Chap. 8.2 "Automatic auxiliary functions"):- Frost protectionPrevents the heating system from freezing- Tank frost protectionPrevents the connected tanks from freezing- Checking the external sensorsChecking the connected sensors during initial commis-sioning using the basic hydraulic circuit that was en-tered previously- Protection against loss of heating waterShuts down when there is a loss of heating water andswitches on again when there is sufficient water pres-sure- Protection against loss of brineShuts down if the brine pressure is too low andswitches on again when the pressure is sufficient- Floor protection circuitOverheating protection for the floor (important forwooden floors)- Pump blocking protectionPrevents seizing of pumps in the system- Freeze protection functionShuts down the compressor if the temperature of theheat source falls below a predetermined valueDescription of the appliance 2
