Parameter /2 defi nes the coeffi cient used to stabilise the temperature measurement. Low values assigned to this parameter allow
a prompt response of the sensor to temperature variations; the reading however become more sensitive to disturbance. High
values slow down the response, but guarantee greater immunity to disturbance, that is, a more stable, precise and fi ltered reading.
Parameter /3 is used to refresh the probe readings displayed; low values of /3 mean the display is refreshed quickly, high values
mean it is refreshed slowly.

Note: parameter /3 only aff ects the display of the probe readings and not the value used for control.
7.3 Digital inputs
iJW manages up to 2 physical digital inputs and 1 multifunction input. See “Installation”.
To associate an input to each available function, set parameters DIA, DIb, … DIr to the value relating to the physical or virtual
digital input. See the parameter table.

(*) Default confi guration with parameters rIA, rIb, ..., rIU = 0; by setting the corresponding parameters rIA, rIb, ..., rIU = 1, the con-
tact logic is reversed and therefore the meanings of open/closed are also reversed.
Example of digital input confi guration.
To associate a function with a digital input, set the value of the corresponding parameter to the value corresponding to the
input, as shown in the following table. For example, to assign the immediate external alarm to input DI1, set parameter DIA to 1.

DIA
Assign immediate external alarm digital input:
0 = Disabled; 1 = DI1; 2 = DI2; 3, 4 = Not available
... 0 4 - S No
The assignment of the controller’s default inputs depends on the settings made in the wizard.
If the opposite logic to the default setting is required, or to correct a wiring error, the logic of the functions associated with the
digital inputs using parameters rIA, rIb, ... rIU can be reversed.

Immediate external alarm (par. DIA)
Activation of the alarm causes:
• message ‘IA’ shown on the display and the “Service” icon fl ashing;
• activation of the buzzer (see par. Hb);
• activation of the alarm relay (see par. DOb);
• deactivation of the compressor output (see par. DOA).
Notice: activation of the external alarm shuts down the evaporator fan only if this follows the status of the compressor
output, as set for parameter /F2. The compressor is shut down immediately due to an external alarm, and consequently the
compressor ON time is ignored (parameter c3).
