IN PROGRAMMING
* The
TST
and
DSP
parameters are adjusted automatically when the expansion valve model
is selected. They should only be changed by qualified staff.
AKO
is not responsible for any
damage that may be inflicted on the installation.
For further information, refer to the user manual available on our
website:
www.ako.com
IMPORTANT:
In the event of an alarm or fault in any of the probes, the
controller closes the liquid solenoid and expansion valve until the problem is
solved.
Messages
*The default value of the password is 5. This may be changed using the
PSS
parameter.
Table of parameters
The equipment's operation functions are divided into 3 different groups.
The
Def.
column indicates the default parameters set in the factory. Temperature values are
expressed in ºC. (Equivalent temperature in ºF) and the pressure values in bar (equivalent
pressure in psi).
Adjustment of parameters
Using the programming menu, you will be able to configure the various parameters in order
to adapt the controller's operation to the needs of its installation.
In order to access the programming menu, press the
PRG
key for 5 seconds, or until the
message ''
PwD
'' is displayed. Using the
N
and
Q
keys enter the password (programmed
into the
PSS
parameter) and press
SET
. Once entered correctly, the password will not be
requested again for 30 minutes.
SET
5"
Press the
SET
button for 5 seconds to exit programming. If no key is pressed for 3
minutes, the controller will exit programming.
