SELFDRIVE mode
If the SELFDRIVE mode is activated (default configuration), the device periodically evaluates the evap-
orator’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 SELFDRIVE mode, it is very important for the probes to be correctly installed, as
described on page 8.
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.
IMPORTANT:
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
While the calibration process is active:
- Manual defrost cannot be activated (
H
key)
- 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 (See page 21).
To perform a manual calibration, access the parameter menu (See page 35) and follow this sequence:
• Access parameter
