# THERMOKON\_WRF07 ## `THERMOKON_WRF07` (FB) `FUNCTION_BLOCK` THERMOKON\_WRF07 ### Representation
### General > Notes: > By the setpoint / parameter `eMode` currently (16.05.2022) only the formation of the room setpoint temperature `rSetpTemp` as well as the setpoint temperature offset `rOffset` is influenced. > The configuration registers (R0 - R69) or coils (C0 - C5) are always set for operation of the WRF07 as a pure room operating device (i.e. without its own internal control). > **\* Device configuration \*** > In registers 0 - 69 or in coils 0 - 5, the current configuration of the device is stored. This is read once at restart / once on every rising edge (xUpdateConfigRead) / cyclically (tTimeUpdateConfigRead) and stored in the arrays `_arwKonfiguration_0` or `arbyKonfiguration_1` stored. > During operation, registers 2 - 69 or coils 0 - 3 are rewritten once at restart / when values change (`_arwKonfiguration_2` or `arbyKonfiguration_3`). In addition, this write access can be triggered by a rising edge at input `xUpdateConfigWrite` This write access must not occur cyclically, as the number of write accesses is limited (EEPROM). > The device configuration cannot be reset to the factory state; in the arrays `_arwKonfiguration_4` and `_arbyKonfiguration_5` the default values are stored and can be loaded / written into the device via input `xResDefault` . > Setpoint / Parameter `rOffsetRange`: A change is transmitted immediately without error, but the new offset is only used after a cold start of the WRF07.
