Warnings
-If the equipment is used without adhering to the manufacturer’s instructions the device safety requirements could be compromised. -The installation location of the equipment must be protected from vibrations, water, and corrosive gases where the ambient temperature does not exceed the value featured in the technical data.
-To ensure a correct reading the probe must be located away from external effects.
-The power circuit should be equipped with a switch for its disconnection of at least 2 A, 230 V, situated near the appliance. The cables will be fed in from the rear and will be typed H05VV-F or H05V-K.
-The section to be used will depend on the local standard in force, however, must never be less than 1 mm.
-The wiring cables for the contact relays must have a section of 2.5 mm.
-Make the connection before plugging in the terminals to the equipment (See Fig. A).
ATTENTION: The equipment is not compatible with AKO-14917 (external communication module) and AKO-14918 (programming key).
Installation
Quick start
Quick start
By using keys 
and 
select the most suitable option according to the installation type in accordance with the table in the “WIZARD” appendix and press SET. The wizard configures the equipment parameters and assigns the input and output functions according to the installation type chosen.
Select the refrigerant gas type used from amongst the following options:
0=R134a 1=R404a 2=R717a 3=R22 4=R410a 5=R507a 6=R744 7=R407a 8=R407f 9=R1234y
10=R448a 11=R449a 12=R450a 13=R454A 14=R454C 15=R455A 16=R1234ze 17=R515b 18=R452A 19=R452b
Select the primary and secondary display units from amongst the following options:
0=bar-ºC; 1=psi-ºF; 2=psi-ºC; 3=bar-ºF; 4=ºC-bar; 5=ºF-psi; 6=ºC-psi; 7=ºF-bar
Configure the rest of the parameters to their default value? :
0=No, the configuration is kept for all the parameters except for C01, C02, C04, C05 C06, C08, and C09.
1=Yes, all the parameters are configured to their default value (see parameters table)
(This option does not affect parameters C01, C02, C04, C05 C06, C08, and C09)
“WIZARD” table
The “WIZARD” table in the appendix is divided into 3 groups of columns. The first describes the different installation types (number of compressors and fans, if they have an inverter, etc.) associated with the INI option.
The second group specifies the function assigned to each relay depending on the INI option selected.
The third group specifies the function assigned to each digital input depending on the INI option selected.

Operation
ESC key
In the programming menu, exit the parameter without saving changes, return to the previous level, or exit programming.
SET key
By pressing this key for 1 second the probe display units change (according to parameter C09).
Pressing it for 10 seconds accesses the programming menu.
In the programming menu, it accesses the level shown on the display or, during the setting of a parameter accepts the new value. UP key
By pressing this key for 1-second probe 2 is displayed for 5 seconds (or probe 1, according to parameter P02). By pressing a second time the probe ambient temperature value will be shown (only if I07 or I08=3).
In the programming menu, it allows scrolling around the different levels, or during the setting of a parameter, changing its value. DOWN key
Pressing this key returns the equipment to its normal operation after an alarm that requires a reset (the causes which triggered the alarm must have disappeared).
In the programming menu, it allows scrolling around the different levels, or during the setting of a parameter, changing its value.
Operation start-up
Upon being supplied with power the equipment will start up in WIZARD mode (INI / 1 flashing), press or to select the most suitable option for the installation type, and check the options in the “WIZARD” appendix.
The wizard configures the equipment parameters and assigns the input and output functions according to the installation type chosen.

Programming output
* Depending on the compressor control type: Proportional=E01; Neutral zone=E01-E06. ** If the compressor is equipped with an inverter, this period of time halves. *** The number of stages depends on the configuration selected in the wizard. Remark 1: The equivalent value in pressure is calculated depending on the refrigerant gas
specified in the wizard. Remark 2: In the event of the energy-saving and the variation in the set point per digital input being activated at the same time, the variation in the set point per digital input will always prevail.
