(1) The default value is 1 (NTC input, see the label on the instrument).
(2) Positive values: active input when the contact is closed; negative values: 1= Active when contact is open
(3) This parameter is visible in versions with optional buzzer.
(5) If alarm are relative, the HAL parameter must be set to positive values and the LAL parameter to negative values
(6) Within the deF folder two folders: dd (daily defrost) and Fd (Festive Defrost); the first folder includes d1& d8 parameters (working day defrost start); the second
folder, instead includes F1& F8 parameters (Festive defrost). The two folders are visible only if dit =3 and RTC is present.
(7) WARNING! positive or negative values change polarity
(8) Referred exclusively to high and low temperature alarms
* VALUE column: to be filled manually, with custom settings (if different from the default value).
** LEVEL column: indicates the level of visibility for parameter that can be accessed by a PASSWORD (see the related paragraph)
*** PA2 is visible (it will be requested, if specified) at level 1 and can be set (it can be modified) at level 2
(!) WARNING!
" If one or more of these parameters highlighted with (!) are modified, the controlller must be switched off and switched on again to ensure correct operation.
" It is strongly recommended, anyway to switch off and switch on again the controller anytime parameters have been changed to prevent malfunctioning on configuration
and/or ongoing timings
