ADAPTIVE mode
If the ADAPTIVE mode is activated (default configuration), the device periodically evaluates the evaporator's heat transfer, managing the
available resources to maximise it.
The defrosts are minimised, adapting to the changing conditions of the cold room, reducing heat input into the refrigerated space, thermal
stress in the evaporator and energy consumption.
Operation of the evaporate fans is optimised taking into account the compressor status, evaporate temperature, frost level, opening of
the door, etc.
The control function of the drainage resistor minimises its activation (moments before starting a defrost), thereby reducing energy consumption.
To achieve correct operation of the ADAPTIVE mode, it is very important for the probes to be correctly installed, as described on page 3.
Calibration
During the first hours of operation, the device performs two calibrations automatically, during which the display shows the CAL message.
Calibration may take several hours and include several refrigeration and defrost cycles.
During the calibration processes, the following should be avoided:
• Opening the cold room door
• Turning the controller off or putting it on stand-by
• Changing controller parameters, including the set point
IMPORTANT:
While the calibration process is active:
• Manual defrost cannot be activated (
• The continuous cycle cannot be activated
• The set point change function cannot be activated
If calibration cannot be performed, or if an important part of the installation is replaced (compressor, evaporator, etc.) it is advisable to
perform a manual calibration.
It is also recommended (not essential) to perform a manual calibration, once the installation has completed its commissioning, with a
load inside it and when its operating temperature has been stabilised, after several days of operation, in this way calibration is optimal.
In the event of changing the set point or hysteresis, the device performs a calibration again automatically, except if the set point change
is made using the "set point change mode" function.
To perform a manual calibration, access the parameter menu and follow the sequence indicated below:
• Access parameter b30
• A security code is requested, enter code 63
• Using keys
