1 PREFACE
This manual is for anyone who must install or use the Eco remote
control for Robur evaporative cooler AD.
This manual especially applies to the electrician who must con-
nect the heating unit to the electrical system and to the end user
who must check that it functions properly.
This manual is also for the technicians regarding the main ser-
vice and maintenance operations.

3 ELECTRICAL HOOKUP
We recommend you:
▶ To avoid crossing cables by separating very low connections
from load-referred connections.
▶ While establishing connections to evaporative cooling mod-
ule follow carefully the specic instructions and information
provided by manufacturer.
We remind you that the instrument is not protected from
electrical overloading:
▶ Beware to equip outputs with necessary security devices;
▶ Make sure that employment conditions like supply tension,
environment temperature and humidity are within the indi-
cated limits.
For the connection, follow the diagram in Figure 19.1 p.8 .

Pressed for more than 2 seconds together with DW command, adjusts the screen contrast.
Pressed once with the unit switched OFF (the display shows“oFF”) selects the operating mode: ventilation or cooling only.
DW
During the parameter programming phase it decreases the value on the display.
Pressed for more than 2 seconds together with UP command, adjusts the screen contrast.
Pressed once with the unit switched OFF (the display shows“oFF”) selects the operating mode: ventilation or cooling only.
I/O
Pressed during programming, works like enter key.
Pressed for more than 1 second, switches the cooling unit on or o.
Pressed for more than 2 seconds together with FAN command, changes the default parameters.
Pressed for more than 3 seconds with the keypad locked it allows the keypad to be released temporarily.
FAN
During the parameter programming phase it acts as an exit button.
Pressed briey it shows the fan speed set and allows access to the fan speed modication phase.

Table6.2
Icons
Cooling: when the led is on and the label COOL is shown, the unit is working in cooling mode.
Programming: the led keeps on during programming.
Ventilation: icon lit together with the word FAn, the unit is activated in ventilation mode.The 3-notch bar indicates the speed at
which ventilation is active: only one notch F1 / two notches F2 / three notches F3.
7 LOCKING/UNLOCKING THE REMOTE CONTROL UNIT
To lock the remote command unit, the HL parameter value must
be set as YES (see Paragraph 12 p.6 and 13 p.6 ).
With the remote command unit locked, the following operations
are not allowed:
▶ setting the default parameters
▶ setting the remote command unit operating mode
▶ displaying the fan speed
When the remote control is locked, display shows “loc”
when pressing any key.
To temporarily release the keyboard, keep the key pressed
until the word "Loc" changes to "OFF". The keypad automatically
returns to the lock condition after 15 sec. from the last press of
a button.

staller" / "factory", the display shows "PA" and a password may
be required.
1. Press the key to enter the password value.
2. Type the right password using key and , press once
the key again.
3. If the operation has been correctly performed, the rst pa-
rameter of the parameter list will be displayed, otherwise it
will be possible to read and change only the parameters of
the "user" list.
In both cases, when scrolling through the list of parame-
ters the conguration icon " " remains lit.
To access only the "user" list, once the "PA" message ap-
pears, press the key twice without paying attention
to the value of the PA parameter.
12 SETTING PARAMETERS
The device has 3 parameter lists:“User”,“Installer”and“Factory”.
To enter/modify the “User” parameter list, it is not necessary to
insert the right password, instead the correct password is re-
quired to enter/modify the“Installer”/“Factory”parameters.
To enter the parameters list proceed as follows:
1. Press the and keys for at least 2 seconds.
2. The display shows“PA”.
3. To set the “installer” or “manufacturer” list enter the correct
PAssword (see Paragraphs 11 p.6 e 14 p.6 ).
4. To view/modify only the "user" type parameters, press the
key twice.
5. Press or to locate the parameter to alter/set.
6. Press the key to display the parameter value.
7. Press the or button to change the value.
8. Press the button again to go back to the parameter list.
To save changes and exit the parameter setting, press or
wait 30 sec.

17 COMMAND TYPE SELECTION: MASTER/SLAVE
Make sure the evaporative cooler is switched o and
without power supply before performing this operation.
In case of more power modules connected in parallel, just one of
them will be the master of the network, while the others will be
the slave modules.
In order to change a power module into a slave module, make a
bridge between V- and M/S (Figure 19.1 p.8 ).
18 ALARMS
Alarms EA are related to the variation of the oat 1 status.
Parameter Y8 sets the delay in signalling the alarm of full tank;
should oat 1, full tank oat, not change its status within a time
Y8, it means that there is a problem with the tank ll and the
controller signal an alarm.

8
To exclude the alarm set Y8=0.
Parameter Y9 sets the delay in signalling the alarm of empty
tank; should oat 1, full tank oat, not change its status within
a time Y9, it means that there is a problem with the tank ll and
the controller signal an alarm.
To exclude the alarm set Y9=0.
