Level 3 Values
- To DISPLAY the CURRENT VALUE of any parameter, select the required one and press
+ keys simultaneously. Once it is displayed, you can CHANGE VALUE, pressing or
key.
- Press + keys simultaneously to ACCEPT THE NEW. The programming returns to
LEVEL 2 PARAMETERS.
REMARK: If no key is pressed for 25 seconds in either of the previous steps, the controller
will automatically return to the CURRENT TEMPERATURE display status without modifying
any of the parameters values.

REMARK: When time parameters are modified, the new values are applied when the current
cycle is completed. In order for it to have an immediate effect, switch the controller off and
then on again.
7- Parameters transfer
Portable server
AKO-14918 portable server, with no power supply, in
which parameters programmed in a powered controller
can be copied by transfer. Parameters can be transferred
again from the server to other identical powered con-
trollers.
To transfer parameters, other servers are available for
controllers that should be programmed identically in
high quantity without power supply.
9- Warnings
The use of the unit without observing the manufacturer's instructions may alter its safety
qualification.
To ensure correct operation of the apparatus, only NTC type probes supplied by AKO should
be used.
Between -40 ºC and +20 ºC, when the probe is extended up to 1.000 m with minimum
0,5 mm
2
cable, deviation will be less than 0.25 ºC (Probe extension cable ref. AKO-15586).
(*) The intensity specified for each relay is its maximum individual value; if more
than one is connected, the intensity of the addition (COMPRESSOR + DEFROST
+ FAN) must not exceed the total maximum intensity specified in the rating
plate.
8- Maintenance
Clean the controller surface with a soft cloth, soap and water. Do not use abrasive deter-
gents, petrol, alcohol or solvents.

It indicates defrosting is being carried out. In order to display "dEF"
dEF during defrosting, it is essential that parameter d2
is set to option 2.
AH
Flashing with temperature - Sensor 1 temperature exceeds the parameter
programmed in A1
AL
Flashing with temperature - The Sensor 1 temperature is lower than the
parameter programmed in A2
E1 Sensor 1 failure (Open circuit, crossed, temp.> 110ºC or temp.<-55ºC)
E2 Sensor 2 failure (Open circuit, crossed, temp.> 110ºC or temp.<-55ºC)
ES Incorrect sensor configuration (See P4, P8)
