Figure 2-3: Tree for moving around the “User menu”
The access to the “User”, “Service” and “Factory” menus requires a password. The following chapter explains how to manage the passwords.
2.2.2. Password management
There are three levels that may be accessed upon entering a numeric password.
To enter the password, type every single digit in the set order from left to right.
To move from one digit to the next, just press the [ENTER] key.
To move from one digit to the previous, just press the [ESC] key. If the cursor should be on the first digit to the left, then this brings back to the main
window.
The following table shows the value of the default user password:
USER PASSWORD
1234
(modifiable)
Once at the last digit of the password, by pressing the [ENTER] key the software will compare the entered password with those stored in its memory. If the
entered password should not be correct, the message “Wrong Password !!!” will appear for a few instants, all digits will be reset, and the cursor will move
back to the first digit, on the left end of the password space.
To go back with the cursor to the previous password digit, just press the [ESC] key.
By pressing the [ESC] key with the cursor on the first digit on the left, the system goes back by one level.
To change the “User” password access the “Info” menu inside the “User” menu and scroll the masks until the “User” password change mask appears:
Insert a NEW

connected should be active). Following is a description of the main mask areas:
Zone 1: General unit status
Unit off
Unit operating in normal mode
Unit off but with fan in operation at low speed to prevent gas build-up
/ /
Unit operating on steady capacity mode
Normal operation / Maximum flow reached / Minimum flow reached
/
Unit operating on steady residual ∆P mode
Normal operation / Minimum flow reached
NOTE
If the icon flashes and the icons also flash at the same time, this means that the unit is on for post-ventilation of the electric heaters (see the
relevant paragraph in the chapter Heating). The flashing of the icon together with the flashing of the icon indicates that the unit is on because it is
waiting for the Mr Slim external unit to switch off.
Zone 2: Unit detail status
Presence of an active alarm

Direct Freecooling damper in adjustment
Zone 6: “Humidity” devices currently in operation
Dehumidifier active
Humidifier active
When the icon flashes intermittently, the dehumidifier
activation request is in process, though a temperature block is
active (high or low temperature threshold, minimum temperature
threshold).

Press the [ALARM] key once to enter the “Alarm” menu and view the event messages along with their codes.
If there is more than one event, scroll the menu using the [UP] and [DOWN] keys. Press any other button to exit this menu.
INFORMATION
Contact your local service centre for support.
2.7.1. Alarm or signal events
First of all, a distinction should be made between two types of event:
•Signal: event that does not stop anything and does not compromise the unit operation. It helps to set the alarm cumulative.
•Alarm: Event blocking a device or the whole unit. It helps to set the alarm cumulative.
In case of an alarm event:
•The red led flashes intermittently in case of a signal.
•The red led is fixed in case of an alarm event.
•The main mask lights up.
•The area 2 in the main mask displays the alarm icon, represented by an operating buzzer.
•The area 3 of the main mask displays an icon reporting the cause of the alarm and, next to it, the type of event (Signal/Alarm) and the associated
event code.
By pressing the [ALARM] key once, the event detail mask appears. This mask provides the following information:
•Event type (Signal/Alarm).
•Event code.
•Rearm type (Manual/Automatic).
•Event position (Compressor/Circuit/Unit/System).
•Action type (compressor/circuit/unit/water circuit/heater/humidifier/specific function block).
•Event description.
The event is reset by pressing the [ALARM] key in the “Alarm” menu. If the [ESC] key is pressed, there is no reset and the event stays active.

3. STARTING THE UNIT
3.1. UNIT POWER SUPPLY
ATTENTION
Connect the unit to the power supply at least 8 hours before starting it; if this is not done, the guarantee will become null
and void.
ATTENTION
Pay attention to the fans. They are kept on at reduced speed when the power is connected, even if the unit is switched off
from the terminal, and while the controller has not yet started, to ensure the dispersion of possible gas leaks.
When the unit is fed, wait approximately 35 seconds before the application starts to run. This time interval may not be cancelled because it is necessary for
the control board to initialise the user terminal. In this phase the user terminal display is lit but does not display anything.
When starting the programme, ventilation starts automatically without any delay, unless the unit is connected to the local LAN network. In this case, each
unit of the network is activated after a delay in seconds equal to the unit LAN address multiplied by 5, in order to prevent the evaporating fans of all the units
from starting at the same time when the power returns after a black-out. This risk cannot be avoided if there are several units that are not connected with
each other in a network.
During start-up of the direct expansion units, a control is carried out to check that the sequence of the phases is correct before ventilation is started. If it is
not correct, ventilation is not started and the incorrect sequence of phases alarm is triggered.
3.2. VENTILATION START-UP
There are different procedures for starting or stopping the unit: using the user interface buttons or selecting from the display. The procedures take the
following priority in case of conflicts (from highest to lowest priority):
1. On/Off from user interface.
2. On/Off from U5 digital input of the controller.
3. On/Off from local network (LAN).
4. On/Off from time bands.
5. On/Off from supervision.
Using the user interface
The “On/Off” parameter is displayed on the main mask. “Off” means that the unit is switched off while “On” means that the unit is switched on.
Proceed as follows:
•Switching On: Move to the “On/Off” parameter by pressing [ENTER] and then press [UP] or [DOWN] until “On” appears. Press [ENTER] again to confirm. If “On”
continues to be displayed it means that the unit has been switched on.
•Switching Off: Move to the “On/Off” parameter and change to “Off” using the same procedure used to switch the unit on. Press [ENTER] again to confirm. If “Off”
continues to be displayed it means that the unit has been switched off.
Using the digital input
Only if the digital input is present and if the "Enable On/Off from digital input" has been set at "Yes" in the “Regulations” menu which requires the “Service”
password.
Proceed as follows:
•Switching On: Close the remote On/Off contact. The corresponding icon is displayed in the main mask.
•Switching Off: Open the remote On/Off contact. The corresponding icon is displayed in the main mask.
Using local network (LAN) protocol:
This mode requires the unit to be connected in a LAN network.
The On/Off control comes from the Master, that is, the unit whose LAN address is=1.
The corresponding icon is displayed on the main mask.
Using time bands
Make sure that “Clock card not installed” is not displayed in the “Clock” menu.
Check that the “Scheduler config” parameter in the “User” menu is set to “Yes”.
Proceed as follows:
•Switching On: Set the required switching on time in the “Clock” menu. The unit switches on when the set time is reached. The “On from time
bands” message appears in the main mask to show that the unit has been switched on. Note: The unit does not switch on if it is set to “Off from
keypad” or “Off from digital input”.
•Switching Off: Set the required switching off time in the “Clock” menu. The unit switches off when the set time is reached. The “Off from time
bands” message appears in the main mask to show that the unit has been switched off.
After enabling time bands from the “Enable time bands” parameter in the “user menu”, time bands can be set and different setpoints can be specified
according to requirements.

The following must be defined to ensure correct use of the time bands:
1. The type of programming of the time bands:
oStandard: For setting a single programming category (A), with a maximum of 10 time bands, that can be assigned to each day of the week.
oAdvanced: For setting up to 4 different types of programming category (A, B, C and D), with a maximum of 10 different time bands, that can be
assigned to each day of the week.
2. For each day of the week:
oDisable the time bands: On the day selected, the controller runs without the time bands.
oEnable a type of time band (A, B, C or D): On the day selected, the controller runs as programmed.
3. For each time band:
oUnit status: OFF (unit turned off by time bands) or in adjustment mode (unit turned ON by time bands).
oTime band start time (for the first time band, this is fixed at 00:00).
oTime band end time (for the tenth time band, this is fixed at 23:59).
oCooling setpoint.
oHeating setpoint (when applicable and configured).
INFORMATION
The time bands B, C and D are shown only when Advanced programming is selected.
INFORMATION
To use a smaller number of bands, simply set the time a band ends to the same time it begins. In this way, the band in question is
ignored.
Below are a few examples that, in graphical form, use bands A, B and C in the clock menu.
The weekly graph uses band A for Monday, band B for Tuesday, Thursday and Friday, and band C for Saturday, and the bands are disabled for Sunday.
Figure 3-1: Example ofdaily time band settings
Using the supervision protocol
Only if the serial board is fitted.
Check in the “User menu” that the parameters “Serial line enabling” and “On/Off enabling from supervisor” are set at “Yes”.
Proceed as follows:
•Switching On: Send the switching on command from the protocol. The corresponding icon is displayed in the main mask.
Note: The unit does not switch on if it is set to “Off from keypad” or “Off from digital input”.
•Switching Off: Send the switching off command from the protocol. The corresponding icon is displayed in the main mask.

3.3. FORCED VENTILATION ACTIVATION
When a unit is switched off using one of the procedures just described, the off command will be sent to the PAC-IF cards and ventilation will remain in
operation until the Mr Slim units have been switched off. This transitional period will be notified by the ventilation and the compressor icons flashing at the
same time.
In case of s-MEXT unit blocking alarm, ventilation is immediately disabled and the external Mr Slim unit immediately stops.
The blocking alarms are:
•Air flow differential pressure switch
•Clogged filter differential pressure switch
•Heater thermostat
•Fire/Fumes sensor
•Flooding sensor
•Gas leak detected (ventilation forced to maximum level).

5. LOCAL LAN NETWORK MANAGEMENT
5.1. PURPOSE OF THE LOCAL LAN NETWORK
The unit connection to the local network (LAN) allows to perform the following functions:
•Balancing the operating hours among the different units by rotating the reserve units (Stand-by).
•Turning on the reserve units in case other units should turn off due to an alarm, maintenance or power feed interruption.
•Turning on reserve units to offset the excessive thermal load.
•Checking up to 10 units with a single user terminal (shared user terminal).
•Operating with all units based on the average temperature and humidity values read by the temperature probes only in the operating units.
OBLIGATION
To allow the LAN to operate correctly, the units must have the same software version and revision (e.g.: ME28r00).
If there is more than one version, update to the latest version or create two different LAN's.
