13.2 Alarm Management Parameters

With parameter PA00, alarms manual reset can be set after the unit is switched off and restarted.
Parameter PA01 defines the delay time with which a probe error is reported due to an anomaly on the probe itself.
Parameter PF23 represents the speed % at which the ventilation is forced due to loss of the adjustment variable
reference (probe alarm). In case of multi-circuit exchangers, this condition only occurs if the failure occurs on all
adjustment probes relative to the controlled circuits.
With parameter PE14, you can enable the use of wet resources even after an anomaly of the ambient temperature
probe. In this case, wet resources are enabled only based on the request in the adjustment mode.
Attention: Enabling wet resources supply in the absence of the ambient temperature probe may result in
overexploitation of the adiabatic sprayers and panels, which in turn reduces the useful life of the adiabatic panels and
inhibits the blocking risk of overtime for spray (which may not be available at a time of real need of the resource).
Also, in the absence of the ambient temperature probe, the antifreeze functions are inhibited with consequent ice
risk.
