Compressore in funzione: l’allarme interviene quando il valore della pressione di aspirazione scende al di sotto di 50kPa (fissi), con un differenziale di 50kPa, per un tempo di 60 secondi (fissi).

3 interventi in un periodo di 45 minuti determinano il blocco del Compressore.

Funzionamento in riscaldamento:

Configurazione DXW (con "Condenser type" = WATER): Compressore fermo: l’allarme interviene se il valore della pressione di aspirazione scende al di sotto di 50kPa (fissi), con un differenziale di 50kPa, per il tempo impostato nel parametro "Low press. alarm delay time".

Compressore in funzione: l’allarme interviene quando il valore della pressione di aspirazione scende al di sotto di 350kPa (fissi), con un differenziale di 50kPa, per un tempo di 60 secondi (fissi).

3 interventi in un periodo di 45 minuti determinano il blocco del Compressore.

Con configurazione ad 1 compressore o 2 compressori con 2 circuiti, viene fermato il compressore 1.

Con configurazione a 2 compressori con 1 circuito, vengo- no fermati entrambi i compressori.

AL10 - Preallarme Alta Temperatura Ambiente

Scheda Board A ingresso analogico B 1 (Room Tempera- ture).

L’allarme interviene quando il valore rilevato dalla sonda di temperatura ambiente supera il set impostato nel parame- tro "Offset room Temperature Hi prealarm" più un isteresi fissa di 0,5°C, e si resetta quando la temperatura scende di 0,5°C sotto al valore impostato.

L’allarme non compare se non dopo che sia trascorso il tempo impostato nel set "Hi/Lo Temperature Alarm delay time" dall’accensione del ventilatore principale.

L'allarme viene solo segnalato.

tial of 50kPa, for 60 seconds (fixed).

The compressor is blocked if three activations occur in 45 minutes.

Running during heating:

DXW Configuration (with “Condenser type” = WATER): Compressor stopped: the alarm is activated if the suction pressure value drops below 50 kPa (fixed), with a differen- tial of 50kPa, for the time set in the "Low press. alarm delay time" parameter.

Compressor running: the alarm is activated if the suction pressure value drops below 350 kPa (fixed), with a differ- ential of 50kPa, for 60 seconds (fixed).

The compressor is blocked if three activations occur in 45 minutes.

Configuration with 1 compressor or 2 compressors with 2 circuits: compressor 1 is stopped.

Configuration with 2 compressors and 1 circuit: both com- pressors are stopped.

AL 10 – Room Temperature High prealarm

Board A, analog input B 1 (Room Temperature).

The alarm is activated when the value measured by the room temperature probe exceeds the set of the "Offset room Temperature Hi prealarm" set, plus a fixed hysteresis of 0.5°C, and is reset when the temperature drops below the set value by 0.5°C.

The alarm is activated only after a time preset in the "Hi/Lo Temperature Alarm delay time" set, starting from the switch- ing on of the main fan.

The alarm is only signalled.

Alarm remotization with voltage free contact on Board B, output C7.

If the "Hi/Lo Temperature Alarm delay time" set is preset to 0, the alarm is deactivated.
