1.1 Description of device

The charging controller ELFAMATIC µC 3000 continuously calculates the correct amount of thermalenergy stored in the storage heater.The outside temperature trend and the tariff information from the power supply company aretaken into consideration.The ELFAMATIC µC 3000 has a backlit LCD.In normal operating mode, the time (or the operating time if autosynchronisation is deactivated),the temperature measured by the outside temperature sensor and all operating states (by pressingthe individual buttons) are displayed on the LCD.In normal operating mode, the backlight is switched off but is switched on again as soon as one ofthe buttons M, P, + or - is pressed. It switches off again after 10 seconds if no button is pressed. LCD: 1 Active parameter2 Current parameter value3 Status display VR / LF / LZ / KU4 Status display ED / SH / SYN

1.4 Putting into operation

1. Basic settingsThe charging model and atmospheric sensor are specified in the respective list.Changes to the individual parameters are adopted immediately after they are entered. If no buttonis pressed for 15 minutes after a change has been made (irrespective of which parameter has beenchanged), the display automatically returns to the default display (time and outside temperatureare shown alternately). For the User and the Fitter Power failureThe clock has a power reserve of approx. 6 hours in the event of a power failure. The setparameters (e.g. charging model) are stored permanently.If the power failure lasts longer than approx. 6 hours, the clock will be set to 00:00 again and flashuntil the time is changed (see above).Summer/winter timeDeviations of approx. 1 hour between the displayed time and the actual time have no effect on thefunctions of the ELFAMATIC µC 3000.

Charging model is not in list or certain parameters must be changed Changes to the individual parameters are adopted immediately after they are entered. If no button is pressed for 15 minutes after a change has been made (irrespective of which parameter has been changed), the display automatically returns to the default display (time and outside temperature are shown alternately). Operating principle The following points are important in understanding the operating principle of the ELFAMATIC µC 3000:

• The temperature used to calculate the output signal is not the instantaneously measured outside temperature but an average value derived from the determined instantaneous values with a trend component.

• During standard operation, the ELFAMATIC µC 3000 functions in autosynchronisation mode, i.e. the timing element is synchronised with the main release automatically while taking the current time into consideration. As a result, it is no longer necessary to set the number of hours since release start (operating time). When put into operation for the first time, the controller operates in forward control mode until it receives the first LF main release pulse; this ensures that charging is performed if an additional release is given during this time.

• With charging models where a permanent release is given, e.g. at the weekend (Powertherm), the ELFAMATIC µC 3000 uses the previous release times to determine the start times for main release and additional release. If the ELFAMATIC µC 3000 is put into operation on a Friday (so that it is not possible to store the release times), synchronisation could take until Monday evening. During this time, the controller operates in forward control mode in order to ensure that charging is performed.
