LA FUNZIONE "LIMIT" PER LA DEUMIDIFICAZIONE.

Il sistema MP2000 effettua un controllo per evitare che la temperatura ambiente si discosti troppo dal setpoint, du- rante la fase di deumidificazione, utilizzando alcuni limiti. Nei "General Parameters" è possibile impostare i limiti di funzionamento della deumidificazione:

"High temperature limit (stop deumidificazione)": differen- ziale di temperatura (rispetto al setpoint) al di sopra del quale viene disattivata la deumidificazione;

"High temperature limit histeresis": differenziale di tempe- ratura (rispetto al precedente) al di sotto del quale viene riattivata la deumidificazione.

"Low temperature limit (stop deumidificazione)": differen- ziale di temperatura (rispetto al setpoint) al di sotto del quale viene disattivata la deumidificazione;

"Low temperature limit histeresis": differenziale di tempe- ratura (rispetto al precedente) al di sopra del quale viene riattivata la deumidificazione.

THE "LIMIT" FUNCTION FOR DEHUMIDIFICATION

The MP2000 system conducts a check to prevent the room temperature from deviating from the setpoint during the dehumidification phase. To reach this state, the system uses some limitations.

The dehumidification operating limitation can be set in the "General Parameters".

"High temperature limit (dehumidification stop": tempera- ture differential (compared to the set point) above which dehumidification is deactivated;

"High temperature limit hysteresis": temperature differen- tial (compared to the previous one) below which dehumidi- fication is reactivated;

"Low temperature limit (dehumidification stop)": tempera- ture differential (compared to the set point) below which dehumidification is deactivated;

"Low temperature limit hysteresis": temperature differential (compared to the previous one) above which dehumidifica- tion is reactivated.

Esempio: Set point temperatura ambiente = 22°C; High temperature limit (stop deumidificazione) =1,2°C; High temperature limit differential = 0,6°C;

Low temperature limit (stop deumidificazione) =1,8°C; Low temperature limit differential = 0,6°C;

La deumidificazione (se attiva in base al parametro rH%) verrà disattivata al raggiungimento della temperatura di 23,2°C (22+1,2) e riattivata a 22,6°C (23,2-0,6), in questo modo prevale la funzione di raffreddamento fino al rientro della temperatura nei limiti; nello stesso modo la deumidi- ficazione verrà disattivata alla temperatura di 20,2°C (22- 1,8) e riattivata alla temperatura di 20,8°C (20,2+0,6), per agevolare il riscaldamento.

Example: room temperature set point = 22°C;

High temperature limit (dehumidification stop) = 1.2°C; High temperature limit differential = 0.6°C

Low temperature limit (dehumidification stop) = 1.8°C; Low temperature limit differential = 0.6°C Dehumidification (if activated based on parameter rH%) will be deactivated after reaching a temperature of 23.2°C (22 + 1.2) and reactivated at 22.6°C (23.2-0.6). In this way, the cooling function prevails until the temperature returns to the set limits; in the same way, dehumidification will be deactivated at a temperature of 20.2°C (22-1.8) and reac- tivated at a temperature of 20.8°C (20.2+0.6), to make heating easier.
