Modular device for DIN-EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep.

State-of-the-art hybrid technology combines advantages of nonwearing electronic control with

high capacity of special relays.

Connection to the Eltako RS485 bus, terminals RSA and RSB.

Up to a total of 128 actuators can be added in this way.

Patented Eltako Duplex technology (DX) allows you to switch normally potential free contacts

in zero passage switching when 230V A/C voltage 50Hz is switched. This drastically

reduces wear. To achieve this, simply connect the N conductor to the terminal (N) and L to

K(L). This results in an additional standby consumption of only 0.1 watt.

The 12V DC supply voltage of the complete RS485 bus is mainly powered at 6W, 12W or

24W by a switch mode power supply unit SNT12-12V DC that is only 1 or 2 pitch units wide.

When all 3 relays of the F4L12 are switched on, 0.7 watt are required.

The top rotary switch

is required for teach-in.

Middle rotary switch

for operating modes:

AUTO1:

The 4 contact surfaces are assigned 'exclusively' when a wireless pushbutton with

double rocker is taught-in as follows: top left closes Contact 1; bottom left closes Contact

2; top right closes Contact 3; bottom right closes Contact 4 (switch-off function). All other

contacts are opened. Wireless window/door contact FTK or Hoppe window handles closes

Contact 4 'exclusively' when a window is opened. A wireless transmitter module can also be

taught-in to close Contact 4 'exclusively'.

AUTO2:

Same as AUTO1, but a wireless pushbutton with double rocker is assigned 'adding':

top left closes Contact 1; bottom left closes Contacts 1 and 2; top right closes Contacts 1, 2

and 3; bottom right closes Contact 4 (switch-off function). All other contacts are opened.

AUTO3:

Activating with wireless CO2 sensor. The contacts close 'exclusively'.

AUTO4:

Same as AUTO3, but activated by the wireless humidity sensor.

AUTO5:

Same as AUTO3, but activated by the wireless temperature sensor.

AUTO6:

Same as AUTO3, but the contacts close 'adding'.

AUTO7:

Same as AUTO4, but the contacts close 'adding'.

AUTO8:

Same as AUTO5, but the contacts close 'adding'.

The bottom and top rotary switches

are used when sensor activation AUTO3 to AUTO8 are in

operation

to set the switch-on threshold for Contact 1 and to set the additional value at which

Contacts 2 and/or 3 close.

Overview of switch-on thresholds

(lower rotary switch):

CO

2 (ppm):

1 = 700ppm; 2 = 800ppm; 3 = 900ppm; 4 = 1000ppm; 5 = 1200ppm;

6 = 1400ppm; 7 = 1600ppm; 8 = 1800ppm, 9 = 2000ppm and 10 = 2200ppm.

Humidity (%):

1 = 10%, 2 = 20%, ... 10 = 100%.

Temperature (°C):

1 = 20°C, 2 = 22°C, 3 = 24°C, ... 10 = 38°C.

Overview of addition values

(upper rotary switch):

CO

2 difference:

1 = 50ppm, 2 = 100ppm, 3 = 150ppm, ... 10 = 500ppm.

Fixed hysteresis: 50ppm.

Humidity difference:

1 = 5%, 2 = 10%, 3 = 15%, ... 10 = 50%. Fixed hysteresis: 5%.

Temperature difference (K):

1 = 1K, 2 = 2K, 3 = 3K, ... 10 = 10K.

Fixed hysteresis: 1K.

The LED

below the upper function rotary switch performs during the teach-in process according

to the operation manual. It shows control commands by short flickering during operation.
