Probe 4 should be placed on the showcase glass.
For each cabinet, only one probe 4 (P4) can be used;
the P4 will send its value to the other sections that are
connected to the LAN.
Functioning with Probe 4 within the LAN:

trA trA = AC if the device has the analog output
OA6
OA6 = AC if the device will use the AUX relay for
regulation
Functioning Without Probe 4:
In this case, regulation is performed by switching the
auxiliary relay ON and OFF on a 60-minute time
base. The ON time will be the AMt value, so that the
relay will be ON for AMt minutes and OFF for

[ 60-AMt ] minutes.
In case of P4 error or if P4 is absent, the output is at
AMA value for the AMt time then the output is at 0
value for the time [ 255 - AMt ] time performing a
simple PWM modulation.
19.6.Auxiliary Output
The auxiliary output is switched ON and OFF by
means of the corresponding digital input or by
pressing and releasing the down arrow key.
