SETTING THE PARAMETERS• Press the SET button to enter the modifying mode of the DIRECT Level parameters.

⇒ Press the SET button to enter the modifiable field.⇒ Use the and buttons to change the parameter’s value.⇒ Press the SET button to confirm change.

• Press the SET + MODE buttons and hold for 3 to 5 seconds to enter the modifying mode of the FACTORYLevel parameters. Enter the code 177 and press the SET button to access the modifiable parameters.

• For the above quick references, press the HOLD button to accept all changes. Press the RESUME button notto accept any changes.

SETTING THE CLOCK• Press the CLOCK button repeatedly to access the hours, minutes, and day of the week. Use the and

buttons to modify the value. Press the CLOCK button again to accept the new value.

CLEARING & MUTING THE ALARM• Press the RESUME button to silence the alarm. Press the RESUME button for 3 seconds to reset any active

alarms. Note the alarm will not be cleared until the alarm condition has been eliminated.

SETTING THE TEMPERATURE SETPOINT• There are 3 operating modes that are relevant to the temperature control: UNOCCUPIED, COMFORT, and

NIGHT-TIME- . Press the SET button to enable modification of the above 3 modes. Use the and

buttons to change the setpoint. Note the symbol being modified will be in the bottom-right hand corner ofthe display during modification. Press the HOLD button to accept all the changes. Press the RESUME buttonnot to accept any changes.

SETTING THE HUMIDITY SETPOINT• Press the SET button for 3 seconds, the word “set” will appear in the upper-right hand corner of the screen and

the actual humidity reading will become the humidity setpoint. Use the and buttons to change thesetpoint. Press the HOLD button to accept all the changes. Press the RESUME button not to accept anychanges.

ALARMS AND TROUBLESHOOTING

The detection of an alarm brings about:· The activation of the buzzer, if present and enabled (parameter P1 not equal to 0), depending on the type of alarm.· The display of the alarm code and the letters ‘AL’, alternating with the display of the temperature· The de activation of some or all the outputs, depending on the type of alarm· The activation of the alarm relay, if present (parameter H2=1), depending on the type of alarm (WARNING: alarm relay refersonly to Stand Alone models)

Note, when more than one alarm is detected at the same time, the display automatically scrolls through the occurred alarms.

Resetting the alarms

Muting the buzzer:Pressing the RESUME button for less than 3 seconds, whenever an alarm is detected, mutes the buzzer, while the outputsdeactivated by the alarm in question remain de energized. The alarm code continues to be displayed, alternating with themeasured temperature value.

Automatic reset:Some alarms are automatically reset when the cause is no longer present, that is, they are deactivated: relevant messageon the display, buzzer and alarm relay.

Manual reset:Pressing the RESUME button for more than 3 seconds, if the alarm conditions have been removed, the instrument returns tothe normal operation and the alarm relay is de-energized. If, on the other hand, the alarm conditions persist, the alarmsituation in progress remains.

Description of the alarmsDetection is immediate for all alarms except the high and low temperature alarms, which are activated after a period set byparameter P5. When the machine is turned OFF, probe alarms are detected only. The alarms which can be detected aredescribed in the following table:

HI T: High temperature alarmWhen the temperature measured by probe B1 rises above the value specified by the parameter P3 for a period longer thanparameter P5, the buzzer and the high temperature alarm message, HI T, are activated. The alarm relay is not energized.

LO T: Low temperature alarmWhen the temperature measured by probe B1 falls below the value specified by parameter P4 for a period longer thanparameter P5, the buzzer and the low temperature alarm signal, LO T, are activated. The alarm relay is not energized.

CODE TYPE OF ALARM EXPLANATIONHI T High temperature alarm The temperature measured by probe B1 has exceeded the value of parameter P3LO T Low temperature alarm The temperature measured by probe B1 has fallen below the value of parameter P4E ID Alarm from digital input ID3 Digital input ID3 is openE FL Alarm from digital input ID1 Digital input ID1 is openEE EEPROM error Read/write error in non-volatile internal memoryE SR Terminal communication error The terminal doesn’t receive data from the power boardE ST Power board communication error The power board doesn’t receive data from the terminalE1 B1 probe error Ambient temperature regulation B1 probe errorE2 B2 probe error Humidity/auxiliary temperature active B2 probe errorLO H Low ambient humidity alarm The humidity measured by probe B2 is over the value of parameter P8HI H High ambient humidity alarm The humidity measured by probe B2 is below the value of parameter P7

E ID: Alarm from digital inputThe unit is able to detect external alarms through digital input ID3. When this is detected as being open, the system waitsfor the delay time P6 then the buzzer and the alarm message E ID are activated. If parameter P2=0 (non serious alarm),there are no other effects; if P2=1 (serious alarm), the alarm relay is energized and there are two types of reaction: ifdigital input ID1 is connected to the fan thermal cut-off , E ID switches off the outputs but not the fan, otherwise it switchesoff the outputs and the fan. When considered to be a non serious alarm (P2=0), Aria resets automatically when the causeis no longer valid. If P2=1 (serious alarm) and, again, the cause that generated the alarm is removed, the RESUME buttonmust be pressed for more than 3 seconds (manual reset).

E FL: Filter alarmThe unit is able to detect a possible filter alarm through digital input ID1 (if H3=2). When this is detected as being openthe alarm message E FL (filter alarm) is activated. The alarm is reset automatically when its cause is removed.

EE: EEPROM alarmSignals a read and/or write error in the non-volatile internal memory (EEPROM), thus highlighting a problem in thestorage of the parameters. If this occurs, try switching the controller off and on again: If the problem persists, pleasecontact the local service.

E SR: Terminal communication errorSignals an error in the serial communication between the terminal and the power board: the terminal does not receive thedata. The alarm message E SR is displayed, the buzzer is activated and all outputs are de energized. The LED on thepower board blinks 3 times (normally once) in 3 seconds. The alarm is reset automatically, that is when communicationis established again. If the alarm occurs, check the two-lead serial connection between the terminal and the powerboard.

E ST: Power board communication errorSignals an error in the serial communication between the terminal and the power board: the power board does notreceive the data. The alarm signal E ST is displayed, the buzzer is activated and all outputs are de energized. The LED onthe power board blinks twice (normally once) in 3 seconds. The alarm is reset automatically, that is when communica-tion is established again. If the alarm occurs, check the two-lead serial connection between the terminal and the powerboard.

E1: B1 temperature regulation probe errorSignals the malfunctioning of the temperature probe used for temperature regulation (B1). Also check the positionof jumper J1. In the case of an alarm, the controller provides the alarm message E1, the buzzer and the alarm relayare activated and all outputs are de-energized, except for the supply fan. The fan stays on to allow air circulation inpublic areas. The alarm is reset automatically, that is when communication is established again.

E2: B2 auxiliary probe errorSignals the malfunctioning of the B2 active probe. Also check the position of jumper J2. In the case of an alarm,the control provides the alarm message E2, the buzzer and the alarm relay are activated and the humidification anddehumidification functions are suspended. The alarm is reset automatically, that is when the sensor starts workingcorrectly.

HI H: High humidity alarmWhen the humidity measured by probe B2 rises above the value specified by parameter P8 for a time greater thanP5, the high humidity alarm signal HI H is activated. The alarm relay and the buzzer are not activated

LO H: Low humidity alarmWhen the humidity measured by probe B2 falls below the value specified by parameter P7 for a time greater thanP5, the low humidity alarm signal LO H is activated. The alarm relay and the buzzer are not activated.
