Initial configuration
The AKO-16526 controller can be adapted to different types of installation according to the different options chosen
in the set-up wizard.
Before completing the wiring, make sure you are familiar with the details of the installation in order to configure it
correctly.
It is advisable to note the following points:
Compressor
Whether the controller should switch the compressor on and off (InI= 2, 3, 5, 6, 7 or 8) or whether the compressor
is switched on and off by the low pressure switch (InI=1 or 4).
Defrost
Defrosting method used:
Electric (InI= 1, 2 or 3) Air (evaporator fans) (InI= 4, 5 or 6)
Hot gas valve (Condensing unit) (InI= 7 or 8)
Solenoid/EEV
Type of solenoid/EEV used:
• PWM-controlled EEV (without liquid solenoid) (u00= 1)
• Stepper-controlled EEV (u00= 2). Requires an external controller for the EEV. For more information, please refer
to the application note available on our website.
Options u00= 1 and u00=2 require the use of a superheating temperature sensor (S5) and an evaporator pressure
sensor (S6).
Analogue outputs
The analogue output (ANALOG OUT) enables communication between the controller and the external controller of
the electronic expansion valve (if u00=2), or with the frequency inverter of the fans (if F10=1), and can be configured
as 4-20 mA output (o30=0) or as 0-10 V output (o30=1).
Consult the specifications of the external controller or drive before setting this option.
SET POINT (temperature)
Make a note of the desired set temperature value.

Pressure sensor type
Type of evaporator pressure sensor installed:
4-20 mA (I61=1) 0-5 V (I61=2) 0.5-4.5 V (I61=3) 0-10 V (I61=4) 1-5 V(I61=5)
Note also the maximum and minimum values of the pressure sensor as well as the units of pressure used (bar or Psi).
