Infrared Remote Control for EC2 
Operating Instructions 
GB 
 
The EC2 series of electronic controls can be easily and quickly 
programmed by means of the remote control unit using single keypad 
operations.  
Until now, in fact, programming the multi-function instruments dedicated to 
the  refrigeration sector was a very complex procedure. This is why 
EMERSON has enhanced the EC2 series with the remote control unit, 
which may be used not only to program the controller from a remote 
position but also to allows the user to set the main working parameters 
easily and fast. Today, modifying any parameter of an EC2 unit is as 
easy as controlling the volume of your TV
.   An interesting feature of 
the EC2 series is the possibility of selecting the access code (H3) of each 
controller so as to further simplify the use of the remote control unit. In 
fact, if your control panel includes several controllers, selecting a specific 
access code will allow you to modify only the parameters of the unit the 
code refers to, without interfering with the other controllers. 
Changing the value of a parameter requires a special procedure (see 
'ENABLE' button). Further safety is also provided by the 'H2' 
parameter that allows you to protect your system from unwilling or 
unauthorised access or modification of all set data.

REMOTE CONTROL UNIT: KEYPAD  
On the basis of the function performed, the buttons on the remote control 
unit have been grouped as follows: 
• 
Buttons to activate / deactivate the use of the remote control unit 
• 
Pre-programmed buttons for the modification of the values of the main 
parameters 
• 
Buttons for the remote control of the EC2 keypad 
BUTTONS USED TO ACTIVATE/DEACTIVATE THE USE OF THE 
REMOTE CONTROL UNIT 
The buttons shown on the left are the remote 
control unit ON/OFF buttons. They also allow you 
to memorize any new parameter value. 
Note: A red LED indicator will be displayed on the 
front panel of the controller to acknowledge that a 
signal is being received from the IR handset. 
 
 
 
 
 
 
ENABLE (blue zone) 
enables the use of the remote control unit;    
PRG 
(blue 
zone) 
1) 
ends the programming procedure and 
memorizes the new values given to the 
parameters; 
 
2) silences the buzzer when programming the IR 
controller  via remote control unit; 
ESC (orange zone) 
interrupts the transmission without memorizing the 
modifications; 
0 … 9 BUTTONS:   
allow  you  to  select  the  access  code.  We  advise 
you to give each controller a specific access code, 
especially when your control panel includes 
several IR instruments or when all of them  are 
exposed to the beam of the remote control unit. In 
this way you will be able to modify exactly the 
parameters you want to change, without 
interfering with the data of the other controllers. 
(See also 'How to use the remote control unit' 
and 'How to select the password'). 
For the correct use of the buttons see 'How to use the remote control 
unit'
 next page. 
BUTTONS USED TO MODIFY THE MAIN PARAMETERS (DIRECTLY 
ACCESSIBLE BUTTONS)    
The most frequent parameters are directly 
indicated on the remote control unit. They are 
grouped in three zones: 
 
temperature parameters (grey zone);                     
 
defrost parameters (white zone);                    
 
superheat parameters (grey zone).           
 
For the correct use of the buttons see 'How to 
use the remote control unit'
 next page. 
 
 
 
 
 
BUTTONS FOR THE REMOTE CONTROL OF 
THE EC2 CONTROLLER 
The green zone of the remote control unit reproduces exactly the keypad 
of the EC2 instruments and allows you to perform the same operations, as 
if you were directly acting on the keypad. 
Here are the main functions of the buttons: 
 
SEL 
displays the value of the 
selected parameter 
 
 
1) goes to the next parameter 
 
2) increases the displayed data 
(parameters selection phase) 
 
Service (grey)  sends the Neuron ID 
 
 
1) goes to the previous parameter 
 
2) decreases the displayed value 
(parameters selection phase)
