LAE CONTROLLER WITH BUTTONS - SERVICE INSTRUCTION
Basic operation
The power supply is turned on by means of a rocker switch located on the control panel of the device or by pressing the button
of the controller. The switching condition is signalled by the values of the air temperature in the chamber appeared on the controller’s
display.
In order to display and modify the required temperature of the chamber:
Press and hold the button
for half a second to display a current
programmed temperature value.
Press and hold the button
then:
Press the button
to increase the temperature value.
Press the button
to decrease the temperature value.
After release of the button
the newly programmed value is stored.
Since then the controller will start running a new programme.
Defreezing (defrosting):
During operation of the device the message “
dEF
” appears on the display at regular intervals, this means that the device operates in the
defreezing mode of the cooler. The defreezing cycle and its duration are determined by the producer of the device and user does not
affect this parameter. If due to the difficult operating conditions of the device the additional defreezing of the cooler is needed, press and
hold the button
for 2 seconds. The message “
dEF
” will appear on the display. The defreezing process will stop automatically after
reaching the time or temperature programmed by the producer.
Alarms:
The meaning of messages that can appear on the display:
E1
- Chamber temperature sensor damaged. The controller will start the device in a time cycle according to the times programmed by
the producer. Defreezing will function normally. Call the service in order to remove the defect.
E2 -
Evaporator temperature sensor damaged. The controller will not run the automatic cycle and manual defreezing. In such a case the
only possibility of defreezing the cooler is turn off the device and wait for the natural ice melting on the cooler. Call the service in
order to remove the defect.
dEF -
Defreezing cycle activated (see section:
Defreezing
)
REC -
Evaporator drainage after defreezing process
CL -
Warning: condenser must be cleaned

Clean the condenser, see: page 6 – section: Operation. After cleaning of the condenser follow the below instruction.
In order to turn off the alarm
CL
reminding that the condenser must be cleaned (every 4 weeks):
- press the button
until the display shows the message
CND
,
- then holding the button
, press the button
.
After these steps the parameter CND is zeroed and the cycle is set up to the beginning.
NOTE! Keypad lock
The most common mistake made by the users involves
locking the keypad unintentionally
resulting in lack of access to the
controller menu. The non-verification of the locking option setup results in sending the controller back to the distributor as ‘damaged’.
The keypad lock allows avoiding the undesirable and potentially dangerous tampering if the controller is installed in an easily accessible
place. In the menu INFO, set the parameter LOC=YES in order to turn on the keypad lock.
In order to resume the operation of the
keypad, set the parameter LOC in the value NO.
In order to unlock the keypad
- press the button
until the display shows the message
LOC
,
- then holding the button
, press the button
.
- in order to exit this menu, press the button
or wait 10 seconds.
Switching the device into the mode ECO
The operation of the device can be quickly changed into the mode ECO (switching the device into alternative
setups). The mode ECO functions most effectively under proper operating conditions of the device (i.e. low door opening
frequency, putting products pre-refrigerated or frozen to the chamber). Under such conditions the function ECO allows
saving a part of energy in relation to the operation with the basic settings. In order to switch between the standard mode
