1.1 Description of device
The charging controller ELFAMATIC µC 3000 continuously calculates the correct amount of thermal
energy stored in the storage heater.
The outside temperature trend and the tariff information from the power supply company are
taken 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 pressing
the 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 of
the buttons M, P, + or - is pressed. It switches off again after 10 seconds if no button is pressed.
