(1) See Duty Cycle diagram

(2) Positive values: active input when the contact is closed; negative values: active input when contact is open.
(3) Parameter can be seen in models with optional buzzer. 
(4) If the alarms are relative, the parameter HA1 is set to positive values and LA1 to negative values.
(6) In the deF folder there are two folders: “dd” (daily defrost) and “Fd” (Festive Defrost); the first folder includes dE1…dE8 parameters (working day defrost start) and the
second folder includes F1…F8 parameters (Festive defrost) The two folders are only visible if dit =3 and RTC is present. 

NOTE:  DO NOT confuse the days d0...d6

related to the nad folder with dE1...dE8 daily defrost

(7) WARNING! positive or negative values change polarity
(8) Refers exclusively to high and low temperature alarms

(9) Example: configure H24= 9 for dual evaporator function

* VALUE column: to be compiled manually with any custom settings (if different from default value).
** LEVEL column: indicates the visibility level of parameters accessed using a PASSWORD (see relevant paragraph)
**** PA2 is visible (or will be requested, if specified) at level 1 

in the CnF folder 

and can be set (modified) at level 2 

 in the diS folder

(!) WARNING!

• If one or more parameters marked with (!) are modified, the controller must be switched off after the modification and then switched back on

PLEASE NOTE

: We strongly recommend that you switch the instrument off and on again each time parameter configuration is changed in order to prevent malfunction-

ing of the configuration and/or ongoing timings.

parameters H23-H24  FOR ID 985LX(/C/CK) MODELS ONLY

•The ID 983LX M -  ID 985LX M models do not have a dual evaporator system and therefore do not possess the features and parameters that are specific to
dual evaporators.

0= Defrosting is enabled by controlling that the temperature of the 1st evaporator is
lower than parameter dSt, 
1 = Defrosting is enabled by controlling that at least one of the two probes is below its
end of defrosting temperature (dSt for the 1st evaporator and dS2 for the 2nd evapora-
tor) 
2 =  Defrosting is enabled by controlling that both the probes are below their respective
end of defrosting set points (dSt for the 1st evaporator and dS2 for the 2nd evaporator)
