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 types 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 mm².
-The wiring cables for the contact relays must have a section of 2.5 mm².
-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
| 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=R404A 1=R134A 2=R407A 3=R407F 4=R410A 5=R450A 6=R513 7=R744 8=R449A

36=R427A 37=R438A 38=R500 39=R502 40=R503 41=R600 42=R600A
| 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
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
which require 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.
In order to start the wizard again, disconnect the unit’s power supply, reconnect it and, during the subsequent 8 seconds, press the key sequence N , , SET.
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, 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.

Table of parameters and messages
The Def. column indicates the ex-works configured default parameters. The
pressure values featured on the table are expressed in bar and those for
temperature in ºC. If the wizard meanwhile
selects another set of units (parameter C09), the equipment will make the
conversion automatically.
Level 2
Read only parameters can only be edited using the INI wizard.
