Quick guide
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:
ŸThe function of the digital inputs depends on the configuration.
ŸThe recommended currents and powers are the maximum working currents
and powers.
Description
Key function
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.
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
parameter, it accepts the new value.

Recommendations
Disconnect the voltage before carrying out any operations inside the electrical panel. All wiring should be according to current standards and should be carried out by authorised staff. Only carry
out the wiring foreseen in the wiring diagrams. Using the electrical panel not observing the manufacturer's instructions may alter the appliance's safety requirements. A tool is needed to remove
any fixed part.
Panel installation:
It is advisable to leave a clean safety space without obstacles around the panel.
Do not knock or make sudden movements on the panel.
Carry out the wiring according to the installation manual.
The probes and their cables should NEVER be installed in a conduit together with power, control or feeder cables.
The earth terminals that the panels contain are installed to guarantee the continuity of earthing, however, earthing is not carried out by the terminal and should be carried out outside the panel.
The neutral ratings are of the TT type. The IT rating should not be used.
Circuit breakers (protective switches) are of the phase/s + neutral, curve C type, guaranteeing switching and protection against overcurrents.
Close the panel when your are not working on it.
Residual current protection outside the electrical panel according to low voltage electrotechnical regulations.
The panels comply with European Standards EN 61439-1 and EN-61439-3 for the electrical panel and EN-60730 for the control board.
Terminals for copper external conductors.
Checks before starting the panel up:
Power supply voltages and frequencies will be the ones that figure in the "Technical specifications" section.
Check that there are no loose parts or foreign bodies on connections or switchgear.
Check that there is no dust or damp inside the panel.
Check the correct fastening of the switchgear and components.
Check the correct tightening of the screws and power connections.
Check the correct connection of the power conductors.
Check the correct insulation of the outer lines and that they do not mechanically force the inner connections of the panel.
Check that the maximum current of the FK1, FK2 and FK3 motor guards has been set correctly (depending on the model).
Before starting the installation up, we recommend preheating the compressor's housing.
Checks during the panel start-up:
Check that no electric arcs occur.
Check that the relays or contactors do not produce ratios.
Check that there is no overheating in cables, controllers and the rest of the switchgear.
Checks after the first 24 hours of operation:
Check that no overheating occurs.
Retighten screws and power connections.
Periodical preventive maintenance:
The panel should remain closed using its lock.
Retighten the power connections once a year.
Check the wear of the switchgear once a year.
Clean the outer surface of the panel with a soft cloth, water and detergent. Do not use abrasive detergents, petrol, white spirits or solvents.
