Direct access to the parameters by selecting the category
The confi guration parameters can also be accessed via the category, as listed in the table below. The summary of operating parameters also shows the
corresponding category for each parameter. To access the categories menu, press prg when the parameter symbol is displayed. Then use UP and DOWN to
scroll the categories. Press set to display the fi rst parameter in the selected category.

Probe confi guration (/A2 to /A4)
In the MasterCella series, these parameters are used to confi gure the operating mode of the probes: 0 = probe absent; 1 = product probe (display only); 2
= defrost probe; 3 = condenser probe; 4 = antifreeze probe.
Digital input confi guration (A4, A5, A9)
In the MasterCella, this parameter and the model of controller used defi ne the meaning of the digital input:
0 = input not active;
1 = immediate external alarm, normally closed: open = alarm;
2 = delayed external alarm, normally closed;
3 = enable defrost from external contact: open = disabled (an external contact can be connected to the multifunction input to enable or disable the defrost).
4 = start defrost when closing the external contact;
5 = door switch with compressor and fans off: open = door open;
6 = remote ON/OFF: closed = ON;
7 = curtain switch: closed = curtain lowered;
8 = low pressure switch input for pump-down: open = low pressure;
9 = door switch with fans only off: open = door open;
10 = direct/reverse operation: open = direct;
11 = light sensor;
12 = activation of AUX output (if confi gured with the parameters H1 or H5): opening = deactivation;
13 = door switch with compressor and fans OFF and light not managed;
14 = door switch with fans OFF and light not managed.
Confi guration of AUX1 and AUX2 relay outputs (H1 and H5)
This establishes whether the fourth and the fi fth relay (present only if featured on the model) are used as auxiliary outputs (e.g. demister fan or other
ON/OFF actuator), as an alarm output, as a light output, as a defrost actuator for the auxiliary evaporator, as a control for the Pump-Down valve or as an
output for the condenser fan.
0 = alarm output: normally energised; the relay is de-energised when an alarm occurs;
1 = alarm output: normally de-energised; the relay is energised when an alarm occurs;
2 = auxiliary output;
3 = light output;
4 = auxiliary evaporator defrost output;
5 = Pump-Down valve output;
6 = condenser fan output;
7 = delayed compressor output;
8 = auxiliary output with switch off;
9 = light output with switch off;
10 = output disabled;
11 = reverse output in control with dead band;
12 = second compressor step output;
13 = second compressor step output with rotation.
Warning: mode H1/H5=0 is useful for signalling the alarm status even when power is cut off.
Note: in the models fi tted with only one auxiliary output, to associate the button
relay needs to be assigned for the auxiliary functions to AUX2 rather than AUX1. The operation can be performed using the programming kit PSOPZ-
PRG00 and the programming key PSOPZKEY00/A0.
Date and day of defrost event (parameters td1 to td8)
0= no event; 1 to 7= Monday to Sunday; 8= from Monday to Friday; 9= from Monday to Saturday; 10= Saturday and Sunday; 11= every day.
