Front Panel And Buttons; Led Display - Indicators - Carel IR32M Manual

Each Infrared controller comes complete with:
•
Wide Range power supply
•
display 2 and 1/2 digits
•
temperature decimal point
•
LEDs indicating the outputs status (the number of LEDs depends on the model)
•
4 keys for programming the unit (except IR32M);
The following options are also available upon request:
•
Universal power supply (IR32S only)
•
alarm buzzer
•
infrared receiver for programming the unit via remote control
•
serial card for connection to a supervisory and/or telemaintenance system such as Carel MasterPlant
for the control and regulation of refrigeration units.
Note: you are requested to indicate the optional functions you need when placing the order. Only the serial
card can be fitted after the controller has been installed. The IRDRSE and IR32SOU versions are not
equipped with the serial output.
LED display
The display shows the temperature values (range: -40/90 or -40/+130 with PTC sensor). The temperature
measured by the sensor is displayed to a 10th degree resolution ranging from -19.9 to +19.9. It is possible to
exclude the decimal part of the degree by modifying the value of the /6 parameter. The display will show one
of the following values/codes, depending on the function being performed.
• normal functioning: value measured by the ambient sensor;
• parameter selection stage: code of the parameter or its value;
• when an alarm condition occurs: the code of the alarm flashes alternatively to the value of the
temperature.
Indicators
On the display there are some luminous indicators (see ƒ to ˆ above). They indicate:
3 current transmission via remote unit (the controller must be equipped with IR receiver);
4 compressor ON routine (IR32S, IR32Y, IR32C, IR32P e IRDRC);
if the IR32S as been set to work as the 'T' model (see parameter H1=0), this LED indicates the status
(ON or OFF), of the controlled output (compressor or other devices); in the IRDRSE/S0 models comp
indication is replaced with the symbol
4b continuous cycle ON routine (all models except IR32M)
5 fan ON routine (models IR32C, IR32P and IRDRC);
second sensor reading (model IR32M);
REVERSE function mode (heating) - models IR32S - configured to work as thermostats (H1=0)
6 fourth relay active (IR32C and IR32P only)
7 defrost ON routine - models IR32S, IR32Y, IR32C and IR32P; in IRDRS, IRDRSE and IRDRS0 models
the indication def is replaced with the symbol
8 decimal point
