– SELECTING THE EVAPORATOR FAN SPEED
Operate as follows:
1.
Make sure the device is in the "on" status.
2.
Make sure that the keyboard is not locked and that no procedure is in progress.
3.
Press and release the
key (1), press and release the
key (2) and then press and release the
key (3) or
the
key (4). The LED bars will supply information relative to fan speed (for example, one bar corresponds to
speed 1, two bars on correspond to speed 2, three bars on correspond to speed 3, etc.).
Alternatively:
4.
Make sure the device is in the "run" status.
5.
Make sure that the keyboard is not locked and that no procedure is in progress.
6.
Press and release the MENU key and then press and release the
key or the
key to select the evaporator
fan speed
7.
Press and release the
key or the
key to modify these values and then press the ESCAPE key to memorise
it.
Operate as follows to exit the procedure:
8.
Press and release the ESCAPE key or do not operate for 60 s.
The fan is switched on at the selected speed after 5 s from release of the
key or the
key.

– MANAGEMENT OF THE TEST REGARDING CORRECT INSERTION OF THE NEEDLE PROBLE
If the needle probe is enabled, i.e. the parameter P3 is set at values different to 0; the temperature-controlled cycles are
preceded by a test on two phases for the verification of the correct insertion of the needle probe.
The second phase is only performed if the first is not completed successfully.
The first phase is completed successfully if the "temperature detected by the needle probe - cabinet temperature"
difference is greater than the value established with parameter r17 in at least 3 controls out of 5 (the controls are
performed at 10 s intervals, consider the difference without sign).
The second phase is completed successfully if the "temperature detected by the needle probe - cabinet temperature"
difference is 1°C/1°F higher with respect to the previous control in at least 6 controls out of 8 (the controls are performed
at time intervals corresponding to 1/8 of the time established with parameter r18; consider the difference without sign).
If the test is completed successfully, the cycle will be started; if the test is not completed successfully, the buzzer will be
activated for 5 s every 10 s and the cycle will be started with timed-control.
To start the temperature-controlled cycle, press the
key or the
key. After 1 min from the signal that the test has not
been completed successfully without having operated, the cycle is started with time control.
If parameter r17 is set at 0, the test will not be carried out (neither first nor second phase).
