Disposal of the product
The appliance (or the product) must be disposed of separately in accordance with the local waste disposal
legislation in force.
WARNING:
separate as much as possible the probe and digital input signal cables from the cables carrying
inductive loads and power cables to avoid possible electromagnetic disturbance. Never run power cables
(including the electrical panel wiring) and signal cables in the same conduits.

How to restore the Default settings (refer to table of parame-
ters in this sheet)
1) Access parameter EZY (entering password 22 and scroll parameter list).
2) Select the desired confi guration:
• EZY = 0
¼
No changes;
• EZY = 1
¼
Restore of default settings (refer to Table of parameters in this sheet);
3) Exit the setting procedure (holding SET button for more than 3 sec).
4) Power off the device and then power it on again while holding SET button.
5) The display shows “CE” to indicate that the confi guration has been restored.
Switching the device ON/OFF
Press UP for more than 3 s. The control and defrost algorithms are now disabled and the instru-
ment displays the message “OFF” alternating with the temperature read by the set probe.
Manual defrost
Press DOWN for more than 3 s (the defrost starts only if the temperature conditions are valid).
Continuous cycle
Press UP and DOWN together for more than 3 s.

Note:
do not run the power cable less than 3 cm from the bottom part of the device or from the
probes;
for the connections only use copper wires
.
Safety standards
compliant with the relevant European standards. Installation precautions:
the connection cables must guarantee insulation up to 90 °C;
•
for 12 Vac versions use Class II transformers. To ensure compliance with the immunity standards
•
(surge), the transformer must be one of the models specifi ed (see the CAREL price list). For the 12
Vac/dc versions, as double insulation cannot be guaranteed between the power supply and the
relay outputs, only use safety low voltage loads (up to 42 V effective rated value);
ensure a space of at least 10 mm between the case and the nearby conductive parts;
•
digital and analogue input connections less than 30 m away; adopt suitable measures for separa-
•
ting the cables so as to ensure compliance with the immunity standards;
Secure the connection cables of the outputs so as to avoid contact with very low voltage parts.
