Infrared Remote Control for EC2
The EC2 series of electronic controls can be easily and quickly
programmed by means of the remote control unit using single keypad
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.
Power supply 2 x 1.5V alkaline batteries (type UM-4 AAA,
IEC R03) Batteries are supplied.
Operating temperature 0/50°C
Weight 80 g (without batteries)
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
• 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
2) silences the buzzer when programming the IR
controller via remote control unit;
ESC (orange zone) interrupts the transmission without memorizing the
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.

and 'How to select the password').

unit' next page.
BUTTONS USED TO MODIFY THE MAIN PARAMETERS (DIRECTLY
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
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)
