Access With Code - Carel IR32M Manual

The section including directly accessible buttons also comprises 3 buttons that activate/deactivate the
function they represent:
DEFROST SECTION:
START activates/deactivates a manual defrost cycle;
°C evap. displays the temperature value measured by the defrost end sensor (if present) or the
value measured by the second sensor (IR32M model).
Important: this function is always active. Consequently the temperature measured by the second sensor will
be always displayed without having to press the 'START' button or select the access code (see point 5
below).
CONTINUOUS CYCLE SECTION:
C.cont. activates a continuous cycle;
•
to exit the programming procedure see point 4 below.
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;
3.1)
•
press either or
•
press SEL to display the value of the selected parameter;
•
press either or
•
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;
•
exit the programming procedure as described in point 4 below.
4) How to exit the programming procedure
•
press PRG to exit and memorize all modifications;
•
press CANCEL 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.

Access with code

5) How to enable the controller to receive the remote control unit transmission
•
press 'START' 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.
How to select the access code
Setting the access code
All IR32 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 'START' 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 requested value (from 01 to 199);
•
press SEL to confirm the new value and display again the H3 code;
•
press MEMO to memorize the access code and exit the procedure.
Removing the code
•
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.
until the display shows the parameter you want to modify;
to increase/decrease its value;
