Controller for evaporator control
AK-CC 750
ADAP-KOOL® Refrigeration control systems
Menu list
This menu function can be used together with system software type AKM. The description is divided
up into function groups that can be displayed on the PC screen. Within each group it is now possible
to show the measured values, or settings. Regarding the use of AKM, reference is made to the AKM
Manual.
Validity
This menu operation (from May 2015) applies to controller type AK-CC 750, code Nos 080Z0125
with programme version 6.5x.
Function groups
The operation is divided up into several
function groups. When a selection has been
made, push “OK”, and you may continue to
the next display. By way of example, “Common thermostat” has been selected here.
From the measure line the different values can be read. The values are constantly
updated.
In the list of settings the set values can be
seen. If a setting has to be changed, select
the parameter and proceed via “OK”.
Measurements
The various measurements can be read directly. If a graphic display of the measurements is required,
up to eight of them can be shown. Select the required measurements and push “Trend”.
Settings
Settings can only be made for the daily operation. Configuration settings cannot be seen, changed or
written out. They can only be made from the Service Tool programme.
There are four kinds of settings, ON/OFF settings, settings with a variable value, time settings and
“reset alarms”.
Set the required value and push “OK”

Enter the new value or move the sliding scale up or down.
The new value will apply, when “OK” is pushed.

AK-CC 750 Version 6.5x
Go through the individual functions one by one and make the required settings. When settings have
been made for one controller, the set values may be used as basis in the other controllers of the same
type and with the same software version. Copy the settings by using the copy settings function in the
AKM programme, and adjust subsequently any settings where there are deviations.
NB! If a list is required for noting down the individual settings, a printout can be made of it with
a function in the AKM programme. Read the next section, “Documentation”.
Documentation
Documentation of the settings of the individual controllers can be made with the print function in the
AKM programme. Select the controller for which documentation of the settings is required and select
the “Print Settings” function (cf. also the AKM Manual).
Functions
Shown below are function groups with corresponding measurements and settings. A printout of the
given settings can be made using the AKM function “Print Settings” (see above).

2: Skip during the day. This function is applied to skip unnecessary defrost during the
day and when a night blinds is used for the specific appliance.
3: Skip both day/night. This function skips unnecessary defrost and can be applied to
cold storage rooms and frost rooms and refrigeration appliance where night blinds
cannot be used
4: Fully adaptive defrost. This function starts a defrost if a medium ice formation is
detected (does not skip defrost). This setup can advantageously be applied to cold
storage rooms and freezer rooms where the time of defrost is not important.
