RESET ALLARMI

Alcuni allarmi si ripristinano automaticamente quando scompare la causa del loro intervento; altri necessitano di un reset da tastiera.

Per poter resettare un allarme da tastiera è necessario che si sia ripristininata o cessata la causa che lo ha pro- dotto. Ad esempio se interviene il pressostato di sicurezza di alta pressione compressore, il reset può essere effet- tuato solo quando la pressione è scesa al di sotto del set massimo impostato.

Per resettare da tastiera gli allarmi è necessario premere SET per 2s. e comparirà la maschera

ALARM RESET

Some fault alarms reset automatically when their cause is corrected or disappears.

Others require a manual reset from the keyboard.

In order to make possible the reset of a fault alarm from the keyboard, their cause must be corrected.

For instance, if the compressor high pressure switch trips, the fault can be reset only if the pressure has dropped again below the max. value set.

To reset the fault alarms from keyboard, press SET for at least 2s. to display the relevant video page.

Manual Procedure

Premere ENTER per il reset degli allarmi.

Premere HOME per uscire dalla funzione, oppure preme- re FRECCIA GIÙ per passare alla funzione successiva di seguito descritta.

COMANDI MANUALI

Questa funzione è dedicata alla gestione di compressori, resistenze elettriche, umidificatore e valvole di riscalda- mento e raffreddamento che sono posizionati per default in funzionamento AUTOMATICO, cioè gestiti direttamente dal microprocessore.

Le modalità selezionabili sono le seguenti:

AUT Attivazione automatica: i dispositivi si attivano automaticamente quando le condizioni di tem- peratura o di umidità lo richiedono.

ON Attivazione manuale: i dispositivi vengono atti- vati indipendentemente dal controllo di tempe- ratura o di umidità. La procedura rispetta co- munque le tempistiche e gli allarmi. I compres- sori e le resistenze possono essere attivati solo se la temperatura dell’aria ambiente si trova nella campo di regolazione positiva o negativa. Le valvole 010V prevedono l’impostazione del valore di apertura in Volt.

Le valvole a 3 punti (Floating) prevedono l’atti- vazione del relè di chiusura o di apertura per un tempo impostabile.

OFF Disattivazione manuale: i dispositivi sono di- sattivati indipendentemente dal controllo di tem- peratura o di umidità. La richiesta di disattivazione dei compressori viene eseguita immediatamente senza tenere conto del tempo di minima accensione.

In qualsiasi caso i dispositivi possono essere attivati solo se l’unità è abilitata (ventilatore principale acceso).

Si potranno avere, quindi, le seguenti situazioni :

Press ENTER to reset the fault alarms.

Press HOME to quit the function or DOWN ARROW to move on to the next function as described below.

MANUAL PROCEDURE

This function allows the operator to control compressors, electric heaters, humidifier and heating or cooling valves, which are otherwise set to operate in AUTOMATIC mode

by default,

practically they are managed directly by the

microprocessor.

The selectable working modes are the following:

AUT

Automatic activation: the devices automatically

 

start on temperature/humidity request.

ON

Manual activation: the devices start independ-

 

ent from the temperature/humidity request. The

 

procedure follows the timing set and the alarms.

 

Compressors and electric heaters can be acti-

 

vated only if the room temperature value is

 

included in the control range (positive or nega-

 

tive).

 

The 010V valves foresee the opening set

 

value in Volts.

 

The floating valves foresee the open/close re-

 

lay activation according to a setting time.

OFF

Manual deactivation: the devices are deacti-

 

vated independent from the temperature/hu-

midity control. The compressor deactivation request is immediately carried out, bypassing the set "min. time compressor".

All the devices can be activated only if the unit is enabled to work (main fan on).

We can the following situation have therefore:
