Note:
If the display “-2-” flashes alternately with the display “ - 1” a password is possibly provided. The
password is entered or cancelled in the operating level "-2-" under "P__". When requested to enter
a password, enter a numerical combination and then press both control buttons at the same time.
If the wrong password is entered, the display changes immediately to the room temperature "tL1".
The password can be entered as many times as required.

Operating mode “Off” (OFF):
All control functions are switched off (standby). The message "UCH" refers to the standby of the
controller.
If no other entries are made, the current room temperature is displayed alternately with "UCH" after 5
minutes.

A detailed description of the MIC QKL mini 2 alerts can be found on the last page of this document
Display of the room temperature measured by sensor TL1. The room temperature can be hidden in
operating level 2.1 under "dt ". In this case, "___"is displayed. In the event of a sensor fault "ES1",
“----" is displayed alternately with "ES1”.
See note under " tbL”
Display of the cooler block temperature measured by sensor TBL. In the event of a sensor fault “ES2"
"----" is displayed.
Information on temperature measurement " tL1" and " tbL":
The temperature is measured according to the principle of the three-wire measurement technique. In
the case of an extension of the sensor wires, the resistances are compensated for by the three-wire
measurement technique. If wire leads are missing, the sensors TL1 or TBL can also be connected
according to the principle of the two-wire measurement technique. Resistances which inevitably
distort the measurement result can be compensated in the operating level "-2.1-" under "oL1" or
under "oL2" by the entry of a correction factor.

Note:
The setpoint value can be increased or decreased by connecting a correspondingly configured
digital input. In this case, the current setpoint temperature is displayed. After cancelling the
connection, "tSA" and "tSr" display the same value.
Note:
In the case of recirculating air defrost under "cd", "FAn" and a setpoint temperature lower than 0 °C /

Loading the factory setting
During the starting operation of the control, keep both control
buttons pressed down permanently without interruption.
Special functions of the control buttons
It is not possible to initiate a manual defrost under the following conditions:
Standby by user ("ECt", "OFF”), standby by digital input, ("cI1" or "cI2", "Stb").
The flashing fault display LED signals that the initiation of a manual defrost is not
possible under the aforementioned conditions.
Note:
An active defrost can be cancelled with the procedure described above.
