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').

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

Service (grey) sends the Neuron ID

1) goes to the previous parameter

2) decreases the displayed value (parameters selection phase)

For the correct use of the buttons see 'How to use the remote control unit' next page.

HOW TO USE THE REMOTE CONTROL UNIT Access without code

1)HOW TO ENABLE THE CONTROLLER TO RECEIVE THE REMOTE CONTROL UNIT TRANSMISSION

•press the 'ENABLE' button to operate the remote control unit;

•the controller's led indicator above the digits flashes and the first parameter - '/C' - is immediately displayed. If the display shows a code different from /C, it is necessary to introduce the access code (see point 5 below).

2)MODIFYING THE MAIN PARAMETERS

• press either the + or - key relative to the parameter you want to modify. The display will show the code of the selected parameter (see the codes of the parameters listed in the Instruction Sheet of the instrument). Press the button again to display the value associated to the selected parameter and

Access with code

5) HOW TO ENABLE THE CONTROLLER TO RECEIVE THE REMOTE CONTROL UNIT TRANSMISSION

•press 'ENABLE' to operate the remote control unit;

•all the controllers exposed to the beam of the remote control unit will display their own access code;

•select the access code of the controller whose parameter you intend to modify using the numeric section on the remote control unit. Select the code correctly (if the code of the controller is 05, press 0 and 5).

•the controller's led indicator above the digits flashes and, simultaneously, the code of the first parameter '/C' appears on the display.

•perform the same operations described in point 2) or 3) above.

•press + to increase it;

•press - to decrease it.

The section including directly accessible buttons also comprises 3 buttons that activate/deactivate the function they represent:

DEFROSTING SECTION:

START activates/deactivates a manual defrosting cycle;

evap.tmpdisplays the temperature value measured by the evaporator probe (if present) or the value measured by the second probe (Thermometer EC2-000).

Important: This function is always active. Consequently the temperature measured by the second probe will be always displayed without having to press the 'START' button or select the access code (see point 5 below).

CONTINUOUS CYCLE SECTION:

HOW TO SELECT THE ACCESS CODE

SETTING THE ACCESS CODE

All EC2 controllers have no factory-set access codes. The User can choose and set his own access codes by simply modifying the H3 parameter as follows:

•press 'ENABLE' to operate the remote control unit;

•the controller's led indicator above the digits flashes and the first parameter ('/C) appears immediately.

•press to display the H3 parameter;

•press SEL to display its value (default 00);

•press to select the desired value (from 01 to 199);

•press SEL to confirm the new value and display again the H3 code;

•press PRG to memorize the access code and exit the procedure.

REMOVING THE CODE

C.cycle. activates a continuous cycle;

•see point 4 below to exit the programming procedure.

3) HOW TO MODIFY THE PARAMETERS NOT DIRECTLY INDICATED BY A SPECIFIC BUTTON

The other parameters - not directly associated to a specific button on the remote control unit - can be easily modified as follows:

•perform the same operations described in point 1 above until the first parameter '/C' appears on the display;

3.1press either or until the display shows the parameter you want to modify;

•press SEL to display the value of the selected parameter;

•press either or to increase/decrease its value;

•press SEL to confirm temporarily the new value and display again the code of the parameter;

•to modify another parameter repeat the operations described above starting from point 3.1;

•see point 4 below to exit the programming procedure.

4)HOW TO EXIT THE PROGRAMMING PROCEDURE

•press PRG to exit and memorize all modifications;

•press ESC to exit without memorizing the previous modifications;

•do not press any button for at least 60 seconds (TIME OUT). In this way the previous modifications will be cancelled.

•repeat the operations described above and give the H3 parameter the value 00 (H3=00). In this way you can program your controller/s without selecting the access code.

WHAT TO DO IF THE REMOTE CONTROL DOESN'T WORK

•check that the remote control is equipped with batteries aligned correctly;

•replace spent or weak batteries;

•check that there are no obstacles between controller and transmitter;

•periodically clean the transmitter and the controller with a soft cloth;

•remember that the remote control's usable range is within 3 meters away from the controller.

•in case parameters are accessible but the user is not allowed to change values, verify "H2" parameter (refer to the USER manual)
