Model FR4
FR4FR4
FR4 is an electronical control unit 78x35mm) suitable for applications on medium or low tempera-
ture refrigeration units, which has three relay outputs to control compressor, defrost and evaporator
blower as well as two PTC-/NTC-sensor-inputs in order to measure the room temperature and evapora-
tor temperature. Defrosting can be recirculation air as well as hot-gas defrosting. The blower can be acti-
vated during defrosting upon request. The sensor is suitable for refrigeration. The control unit FR4 is suit-
able for refrigeration as well as heating applications only hot-gas heating). Supply voltage may be between
10 and 28V.
The following functions can be adjusted:
•room temperature „only refrigeration“ or „refrigeration and heating with hot gas “)
•automatic defrosting hot gas or recirculating air)
•manual defrosting hot gas or recirculating air)
⇒Faults are shown in the display via flashing indication see point 4).
This present instructions for installation and service is amended by the „operating
instructions for refrigeration units“, KONVEKTA no: BBA-FR4-2AA.

:
Before switching-on the unit, please check once again correct connection.
Never run this unit without housing.
Please install the sensor where it is not accessible for the end customer
Please consider the maximum current which can be applied to each relay see technical data / point 1).
Please ensure that all sensors are installed with enough distance to under-voltage cables. By this, distorted
temperature measurements can be avoided and the unit is protected from voltage interspersion by the
sensor-inputs.

5.1 Example for change of a parameter, here parameter defrost interval “di nt”
For selecting the menu please press and hold button [P]. “SP 1” is blinking in the display. After 5 seconds a „0“
appears. By pressing buttons and the password „213

213“ is set. Now press button [P] once, in order to
confirm the password.
The display now shows the term of the first group „
]
SP“. By pressing buttons
and the other groups
can be selected, by pressing button [P] the respective group is opened.
In order to change the defrosting intervals please browse with buttons and , until group „
]
dEF“
appears in the display. By pressing button [P] you open this group. First the display shows parameter „dtyP“
blinking. By pressing buttons
and you can choose paramenter „di nt“; parameter „di nt“ is now blink-
ing in the display. By pressing button [P] once, the current setting is shown, “di nt” and the adjusted value
“1,30” are blinking alternately. Now the value can be changed. The new value is stored by leaving the pa-
rameter. You can leave the parameter with button
. If you press button
longer, the menu switches
back to the groups, afterwards you can leave the menu by pressing this button longer once again.

FR4 copy-key: Konvekta part no. H11-001-396-C
The unit has a plug socket. Via this plug socket the operating parameters are transmitted from and to the
unit. For this the FR4 copy-key with 5-pole plug is used. The FR4 copy-key is used for factory programming
of units that should have the same parameter configuration, or for a backup of the programming of a unit
so that this can be reconstructed quickly if required.
For transmission of a configuration from a FR4 to the FR4 copy-key UPLOAD), please proceed as follows:
1) Adjust both dip switches of the FR4 copy-key to OFF.
2) Connect the FR4 copy-key with the FR4; use the designated plug.
3) Make sure that the FR4 copy-key is connected with current supply.
4) Check the LED signal of the FR4 copy-key: In case of green LED, a configuration has already been
loaded; in case of green blinking or red blinking LED there is no valid configuration.
5) Press button on FR4 copy-key.
6) Check the LED signal: After pressing the button, the LED will be red and after successful data transmis-
sion the LED will be green.
7) Now FR4 copy-key can be plugged-off.
If this configuration which has been loaded to the FR4 copy-key should now be transmitted to another FR4
unit DOWNLOAD), please proceed as follows:
1) Adjust both dip switches of the FR4 copy-key to ON.
2) Connect the FR4 copy-key with the FR4 that should be programmed; use the designated plug.
3) Make sure that the FR4 copy-key is connected with current supply.
4) Check the LED signal of the FR4 copy-key: The LED should be green; if LED is blinking green or red, no
valid configuration has been loaded and it doesn’t make sense to go on.
5) In case of green LED press button on FR4 copy-key.
6) Check the LED signal: After pressing the button, the LED will be red and after successful data transmis-
sion the LED will be green.
7) Now FR4 copy-key can be plugged-off.

Etdu
Display unlock difference after finished defrost cycle
During defrost cycle it is possible that the tempera-
ture measured by the cell sensor (Pr1) rises exces-
sively (this depends on the position of the sensor
Pr1 to the evaporator).
In order to not indicate this rise, the functions con-
tained in the parameters “dLo” (display lock during
defrost cycle) and “Etdu” (display unlock difference
after finished defrost cycle) are used.
The parameter “dLo” = Lb causes the indication
dEF during a defrost cycle.
Completion of defrost cycle the indication PdEF is
suppressed, as the temperature Pr1
is always under
the value [”SP” + “Etdu”].
