Digital input operating mode: configures the digital input function:
0 = Starts a defrost;
1 = Input from a door switch (see parameter odC);
2 = Activates the auxiliary relay;
3 = Starts Energy Saving (Control Point becomes Set Point +/- value in HES);
4 = Remote On/OFF (puts the controller into standby);
5 = Generic external alarm (normal regulation continues);
6 = Serious external alarm (regulation is stopped).
Configurable digital input polarity:
0 = the digital input is activated by closing the circuit;
1 = the digital input is activated by opening the circuit.
Second digital input operating mode: configures the second digital input function:
0 = Starts a defrost;
1 = Input from a door switch (see parameter odC);
2 = Activates the auxiliary relay;
3 = Starts Energy Saving (Control Point becomes Set Point +/- value in HES);
4 = Remote On/OFF (puts the controller into standby);
5 = Generic external alarm (normal regulation continues);
6 = Serious external alarm (regulation is stopped).
Configurable second digital input polarity:
0 = the digital input is activated by closing the circuit;
1 = the digital input is activated by opening the circuit.
Time interval/delay for digital input 1 alarm: (0 to 255min) it defines the time delay between the detection and the
subsequent signalling of the alarm.
Time interval/delay for digital input 2 alarm: (0 to 255min) it defines the time delay between the detection and the
subsequent signalling of the alarm.
Compressor and fan status when open door:
0 = normal;
1 = Fan OFF;
2= Compressor OFF;
3 = Compressor and fan OFF.
Auxiliary relay configuration:
0 = Alarm;
1 = Dead Band;
2 = Auxiliary;
3 = Second compressor output;
4 = Light output;
5 = Second defrost output.
Alarm relay polarity:
0 = contact [13 – 14] closed with alarm;
1 = contact [13 – 14] open with alarm.
Temperature alarm exclusion with door open: 0 to 255min.
Regulation restart with door open alarm:
0 = no;
1 = yes, regulation will restart after “door open” alarms.
Low temperature alarm of condenser: (-55 to 150°C or -67 to 302°F) when this temperature is reached, the HA2 alarm
will be raised (after the Ad2 delay time has expired).
High temperature alarm of condenser: (-55 to 150°C or -67 to 302°F) when this temperature is reached, the LA2 alarm
will be raised (after the Ad2 delay time has expired).
Differential for temperature condenser alarm recovery: 0.1 to 25.5°C or 1 to 45°F.
