8.18 Alarm history

All recipes
On the SMART-MT, in addition to displaying the active alarms (AL menu),
you can view the history of the last 10 alarms (000 menu).
The instant an alarm appears, the following is saved:
- the alarm code (Par LAL0),
- the date (Par LAL1),
- the hour (LAL2 pair)
- external air temperature (LAL3)
- the temperature of the water entering the PdC (LAL4)
- the temperature of the water leaving the PdC (LAL5)
- the electrical power absorbed by the PdC, if available, otherwise Com-
pressor operation step (LAL6).
On the CAL0 Parameter, select the chronological position (from 0 to 9)
that you want to consult, then view the saved data (LAL0 ÷ LAL6).
on the SMART-MT appears.

8.19 High temperature radiant system
alarm input
Recipe 13
Input 103 (F + / F-) of the TERMINAL BLOCK PCB is configured as a radiant
system high temperature alarm input, therefore:
Closed contact
High temperature
alarm input Radiant
system
Alarm AL08 is activated and the compressor stops.
The circulator, on the other hand, activates for 5 min every 30 min in an
attempt to reset the alarm.

8.20 Low pressure systrem alarm input

Recipe 13
Input 104 (G + / G-) of the TERMINAL BLOCK PCB is configured as system
low pressure alarm input, therefore:
Closed contact
System low pressure
alarm input
Alarm AL10 is activated and both the compressor and the circulator stop.
