In systems in which the drying function had to be interrupted due to DHW heating (e.g.Anl 2.1), storage tank charging does not occur while the drying function is active, providedit is not used for frost protection of the storage tank.Note: The function block parameter can only be accessed when the function has started bydeactivating the function block and activating it again.Functions WE ConfigurationUnderfloor heatingDrying of jointless floors05 °C/24 h25 °C45 °C40 °C/24 hSTOPCO1, 2, 3 -> F05 - 1Temperature rise / 1 to 10 °C/24 hStart temperature / 20 to 60 °CMaximum temperature / 25 to 60 °CMaintaining time for max. temperature / 1 to 10 daysTemperature reduction / 0 to 10 °C/24 hnSTART, nn START, nnn START5.4 Deactivation depending on outdoor temperature5.4.1 OT deactivation value in rated operationIf the outdoor temperature exceeds the limitOT deactivation value in rated operation, the af-fected heating circuit is put out of service immediately. The valve is closed and the pump isswitched off after t = 2 x valve transit time. When the outdoor temperature falls below thisvalue (less 0.5 °C hysteresis), heating operation is restarted immediately.With the default settings, this means that, during the warm season, the system is switched offat an outdoor temperature of 22 °C.Parameter WE Parameter level / Range of valuesOT deactivation valuein rated operation22 °C PA1, 2, 3 / 0 to 50 °C5.4.2 OT deactivation value in reduced operationIf the outdoor temperature exceeds the limit valueOT deactivation value in reduced operationin reduced operation, the affected heating circuit is put out of service immediately.
