1. Operating instructions

1.1 Description of device

The charging controller ELFAMATIC C3000 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 C3000 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.

LCD:

1 Active parameter
2 Current parameter value
3 Status display VR / LF / LZ / KU
4 Status display ED / SH / SYN

Buttons:

M Select menu
P Select parameter
+ Change parameter

1.2 Operation

The time and the level of storage heater charging can be changed or set during normal operation.

Changing/setting time . . .

Button	LCD	Button	Button	Note
Press	VRLFLZKU URHR ED SH SYN	Press + or -	P Press twice	Holding down the button activates rapid setting mode. If no button is pressed for 15 minutes, the set time is adopted automatically and the backlight switches off.

Button	LCD	Button	Button	Note
Press twice	+/- - VR LEL ZKU ED SH SYN	Press + or -	Press	In this menu, the basic charging mode of all storage heaters connected to the ELFAMATIC μC 3000 can be changed by +/-4 °C according to requirement. 1 °C corresponds to approx. 3.5 % more/less charging (max. +/-15%). The charging rate should be changed in small steps only (0.5-1 °C) as any change does not become noticeable until the following day.

Power failure

The clock has a power reserve of approx. 6 hours in the event of a power failure. The set parameters (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 flash until the time is changed (see above).

Summer/winter time

Deviations of approx. 1 hour between the displayed time and the actual time have no effect on the functions of the ELFAMATIC C 3000.

1.3 Troubleshooting . . .

"FU" (open circuit in sensor) or "FS" (short-circuit in sensor) and the time are displayed alternately.

The atmospheric sensor and/or the selected setting for the atmospheric sensor must be checked by a specialist technician.

1.4 Putting into operation

1. Basic settings

The 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 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).

Button	LCD Button		Note

2. Special settings

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 C 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 C 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 C3000 uses the previous release times to determine the start times for main release and additional release. If the ELFAMATIC C3000 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.

2.3 Installation

2.3.1 Controller

The ELFAMATIC C 3000 must be fitted in the bottom row of a distribution board, whereby a gap of one SI circuit-breaker width must be provided at the sides. Shock protection to safety class II is provided if the ELFAMATIC C 3000 is installed in

• a small distribution board to DIN or
• a distribution board to DIN

The ELFAMATIC C3000 consists of a base with terminals for rail mounting as well as the plug-in housing with the electronic components.

The top part of the housing is removed from the base by releasing the lower housing catch using a screwdriver and then pulling off the top part.

The base must be de-energised before the top part of the housing is mounted.

Replacing an existing ELFAMATIC C 2100

The device must be connected as shown in the circuit diagram.

Removal

To remove the controller, release the top part from the base (as described above) and disconnect the connecting cables.

Then release the base from the rail as shown in the illustration below.

Sensor

Normally, the installation location of the atmospheric sensor should be selected according to the following criteria:

• Installation according to the illustration below
  Min. height above ground: 2.5m
• The sensor should be mounted on the side of the building on which the main rooms to be heated are located (avoid mounting on the north side of the building where possible)
• The sensor must be mounted at a sufficient distance from doors, windows, exhaust-air ducts, etc.

The cable between the sensor and control unit must be suitable for mains voltage.
