Continuous cycle mode
This is used to quickly cool the cold room stores
before products are loaded and is activated by
pressing the
key for 3 seconds.
Upon activating this mode, the compressor begins to
operate until the temperature in probe S1 reaches the
set point value, minus the variation indicated in
parameter
C10
. The value of
C10
is always negative,
unless it is 0.
The unit will immediately return to normal operation.
Should it not be possible to reach this point, the
device will return to normal operation once the time
configured in
C9
has elapsed, or by pressing the
key again for 5 seconds.
Set Point change mode
This allows for quick alternation between two working temperatures in the cold room store, modifying the Set
Point in line with the value indicated in parameter
C12
. The aforementioned value may be negative or positive,
which allows for the Set Point to be reduced or increased. If it is configured in 0, the mode is disabled.
It is activated in three possible ways:
Ÿ
By means of an external switch connected to one of the digital inputs. The digital input should be configured
as “Set Point change (
I10
or
I20
=4). Activation through this method cancels any other activation and can
only be deactivated using the same method.
Ÿ
By means of the AKONet application. This requires the device to be connected to a Modbus network (see p. 28).
Ÿ
By means of the CAMM module and the AKO CAMM tool application.
EXAMPLE:
Calibration of probe 1
Parameter
C0
allows for correction of the temperature detected by probe 1; this is particularly useful when the
probe cannot be located in the ideal place.
Set Point locking
Parameters
C2
and
C3
allow for an upper and lower limit to be established for the set point (
SP
), to protect the
product or installation from Set Point manipulation.
