The IR33 range ﬁ tted with the standard CAREL NTC sensor is compliant with standard EN 13485 on thermometers for

measuring the air and product temperature for the transport, storage and distribution of chilled, frozen, deep-frozen/

quick-frozen food and ice cream. Designation of the instrument: EN13485, air, S, A, 1, -50T90°C. The standard CAREL NTC

sensor is identiﬁ able by the printed laser code on "WP" models, or the code "103AT-11" on "HP" models, both visible on

the sensor part.

Safety standards:

compliant with the relevant European standards.

Installation warnings:

• the connection cables must guarantee insulation up to 90 °C; and, if necessary, up to 105 °C

• adequatel y secure the connecti o n cabl e s to the outputs so as to avoi d contact wi t h very l o w vol t age components.

Manual defrost

As well as automatic defrost, a manual defrost can be activated, if the temperature conditions are right, by

pressing "DEF/DOWN" for 5 s.

HACCP functions

ir33 is compliant with the HACCP standards, as it monitors the temperature of the food stored. Alarm "HA"= max. th-

reshold exceeded: up to three HA events are saved (HA, HA1, HA2), from the most recent (HA) to the oldest (HA2),

with a signal HAn that displays the number of HA events saved. Alarm "HF"= power failure for more than 1 min.

and max. threshold AH exceeded: up to three HF events are saved (HF, HF1, HF2), from the most recent (HF) to the

oldest (HF2), with a signal HFn that displays the number of HF events saved. Setting the HA/HF alarm: parameter

AH (high temp. threshold); Ad and Htd (Ad + Htd = HACCP alarm delay). Displaying the details: press "SET" to

access parameters HA or HF and scroll using "UP/AUX" or "DEF/DOWN". Deleting the HACCP alarms: press "DEF/

DOWN" and "SET" for 5 sec. inside the menu, "res" will be shown to indicate the alarm has been deleted. To

delete the saved alarms, press "DEF/DOWN" + "SET" + "UP/AUX" together for 5 seconds.

Defrost event date and day (parameters td1 to td8)

0 = no event; 1 to 7 = Monday to Sunday; 8 = Monday to Friday; 9 = Monday to Saturday; 10 = Saturday

and Sunday; 11 = every day.
