Note: (*¹) If this is the only pump, it switches OFF all compressors and fans; otherwise, it switches ON the other
pump.
(*²) If Pr03=1, the output probe fault alarm on that circuit switches ON the associated anti-frost heating coils.
S/A = Notification - only or auto-reset alarm (settable via parameter).
A/M = Auto or manual-reset alarm (settable via parameter or by number of events/hour).

Alarm Relay
The program offers the possibility of managing a cumulative alarm relay. Enabling of this output
depends on whether or not the associated parameter Alarm DO position HA01 has been set. To
enable it, it is sufficient to set such value as different from zero; if a zero value is kept, the alarm
relay will not be used.
Via parameter Alarm DO logic-{}- PH18, it is possible to establish the polarity (NO or NC) of the
alarm output.
