Maintenance

Clean the surface of the unit with a soft cloth, water and detergent. Do not use abrasive
detergents, petrol, white spirits or solvents.

Precautions

Using the equipment without following the manufacturer's instructions may affect the
device's safety requirements. To ensure that the device operates correctly, only probes
supplied by AKO should be used.
Between -40 ºC and +20 ºC, if the NTC probe is extended up to 1,000 m with minimum
0.5 mm² wire, the maximum deviation will be 0.25 ºC (Wire for probe extension ref.
AKO-15586)
IMPORTANT:
The function of the digital inputs depends on the configuration.

Pressing it for 5 seconds activates the Stand-By mode. Pressing it for 2 seconds the unit
returns to the normal mode. In Stand-by mode, the unit performs no action and the
display only shows the m indicator along with the temperature.
ESC
During configuration, it exits the parameter without saving changes, returns to
previous level, or exits programming.
One short press* shows the non-displayed probe reading (see P8 parameter).
Pressing it for 5 seconds starts/stops the defrost.
During configuration, it allows you to scroll through the different levels, or when
setting a parameter, to change its value.
Pressing for 5 seconds accesses the quick configuration menu.
Pressing for 10 seconds accesses the advanced configuration menu.
During configuration, it allows you to scroll through the different levels, or when
setting a parameter, to change its value.
One short press* displays the current set point value (SP).
Pressing it for 5 seconds accesses change set point.
During configuration, it accesses the level shown on the display or, when setting a
SET parameter, it accepts the new value.
*Short press: Less than 5 seconds.

The defrost will end after this time has elapsed since it started.
F3: Fan status during defrost
It defines the status of the fans during defrost.
A1: Maximum alarm probe 1
Defines the temperature at which the maximum alarm will be triggered. Only affects probe 1.

Defines the temperature at which the minimum alarm will be triggered. Only affects probe 1.
P26: Stoppage owing to pump down
It defines whether this function is active

Flashing 0: Access code (Password) request
You must enter the access code configured on L5 to execute the requested
function. See also parameter P2.

probe limits; NTC: -50 To 99 ºC).
Indicates a defrost is underway. When the defrost process has finished, the
message will continue to be displayed during the time defined in
parameter d3.
Alternating with temperature:
