9Installation instructions geoTHERM VWS 0020046310_012.4 General notes on operating modes and func-tionsThere are five operating modes available for the heatingcircuit and these can be used for time and temperaturecontrol of the heat pump (see Chap. 8 "Control sys-tem").Three additional operating modes are available for theconnected domestic hot water cylinder and circulationcircuit.During start-up, you will tell the heat pump which of theconnection configurations listed in the appendix cor-responds to your installation by entering the number ofthe corresponding hydraulic plan into the controller.Thus all the operating parameters will be set to prede-termined values, so that the heat pump can work opti-mally. However, you can individually set and adapt theoperating modes and functions afterwards.You will find all the information on operating modes, au-xiliary and special functions in Chapter 8, "Control sys-tem".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 wasentered 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 and swit-ches 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 valueAdditionally, there are further settable auxiliary func-tions available (see also Chap. 8.3 "Settable auxiliaryfunctions"):– Timer programmesTo set the heating times for each heating circuit– Holiday programmingProgramming of two holiday periods with date entryand set-back temperature– Party functionCarries the heating and hot water times forward tothe next shut-off point– Energy saving functionLowers the flow setpoint temperature for a presettab-le period– Screed floor dryingFor drying out screed floors– Fixed value controllingSets a fixed flow temperature– Anti-legionella functionKills germs in the tank and in the pipes– Quick testTest function for maintenance– Remote maintenanceDiagnostics and setting via vrDIALOG orvrnetDIALOGDescription of the appliance 2
