WARNINGS

CAREL INDUSTRIES bases the development of its products on decades 
of experience in HVAC, on the continuous investments in technological 
innovations to products, procedures and strict quality processes with in-circuit 
and functional testing on 100% of its products, and on the most innovative 
production technology available on the market. CAREL INDUSTRIES and its 
subsidiaries/affiliates nonetheless cannot guarantee that all the aspects 
of the product and the software included with the product respond to the 
requirements of the final application, despite the product being developed 
according to start-of-the-art techniques. The customer (manufacturer, 
developer or installer of the final equipment) accepts all liability and risk 
relating to the configuration of the product in order to reach the expected 
results in relation to the specific final installation and/or equipment.
CAREL INDUSTRIES may, based on specific agreements, acts as a consultant 
for the successful commissioning of the final unit/application, however in no 
case does it accept liability for the correct operation of the final equipment/
system.

The CAREL INDUSTRIES product is a state-of-the-art product, whose operation 
is specified in the technical documentation supplied with the product or can 
be downloaded, even prior to purchase, from the website www.carel.com. 
Each CAREL INDUSTRIES product, in relation to its advanced level of 
technology, requires setup/configuration/programming/commissioning 
to be able to operate in the best possible way for the specific application. 
The failure to complete such operations, which are required/indicated in the 
user manual, may cause the final product to malfunction; CAREL INDUSTRIES 
accepts no liability in such cases. Only qualified personnel may install or carry 
out technical service on the product. The customer must only use the product 
in the manner described in the documentation relating to the product.

In addition to observing any further warnings described in this manual, the 
following warnings must be heeded for all CAREL INDUSTRIES products: 

• 

prevent the electronic circuits from getting wet. Rain, humidity and all 
types of liquids or condensate contain corrosive minerals that may damage 
the electronic circuits. In any case, the product should be used or stored 
in environments that comply with the temperature and humidity limits 
specified in the manual;

• 

do not install the device in particularly hot environments. Too high 
temperatures may reduce the life of electronic devices, damage them and 
deform or melt the plastic parts. In any case, the product should be used 
or stored in environments that comply with the temperature and humidity 
limits specified in the manual;

• 

do not attempt to open the device in any way other than described in the 
manual;

• 

do not drop, hit or shake the device, as the internal circuits and mechanisms 
may be irreparably damaged;

• 

do not use corrosive chemicals, solvents or aggressive detergents to clean 
the device;

• 

do not use the product for applications other than those specified in the 
technical manual. 

All of the above suggestions likewise apply to the controllers, serial boards, 
programming keys or any other accessory in the CAREL INDUSTRIES product 
portfolio.
CAREL INDUSTRIES adopts a policy of continual development. Consequently, 
CAREL INDUSTRIES reserves the right to make changes and improvements to 
any product described in this document without prior warning.
The technical specifications shown in the manual may be changed without 
prior warning.

The liability of CAREL INDUSTRIES in relation to its products is specified in 
the CAREL INDUSTRIES general contract conditions, available on the website 
www.carel.com and/or by specific agreements with customers; specifically, 
to the extent where allowed by applicable legislation, in no case will CAREL 
INDUSTRIES, its employees or subsidiaries/affiliates be liable for any lost 
earnings or sales, losses of data and information, costs of replacement goods 
or services, damage to things or people, downtime or any direct, indirect, 
incidental, actual, punitive, exemplary, special or consequential damage of any 
kind whatsoever, whether contractual, extra-contractual or due to negligence, 
or any other liabilities deriving from the installation, use or impossibility to use 
the product, even if CAREL INDUSTRIES or its subsidiaries are warned of the 
possibility of such damage.

DISPOSAL

INFORMATION FOR USERS ON THE CORRECT HANDLING OF WASTE 
ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE)
In reference to European Union directive 2002/96/EC issued on 27 January 
2003 and the related national legislation, please note that:
1.  WEEE cannot be disposed of as municipal waste and such waste must be 

collected and disposed of separately;

2.  the public or private waste collection systems defined by local legislation 

must be used. In addition, the equipment can be returned to the 
distributor at the end of its working life when buying new equipment;

3.  the equipment may contain hazardous substances: the improper use or 

incorrect disposal of such may have negative effects on human health and 
on the environment;

4.  the symbol (crossed-out wheeled bin) shown on the product or on the 

packaging and on the instruction sheet indicates that the equipment has 
been introduced onto the market after 13 August 2005 and that it must 
be disposed of separately;

5.  in the event of illegal disposal of electrical and electronic waste, the 

penalties are specified by local waste disposal legislation.

W

arranty on the materials:

 2 years (from the date of production, excluding 

consumables).

A

pproval:

 the quality and safety of CAREL INDUSTRIES products are 

guaranteed by the ISO 9001 certified design and production system.

IMPORTANT: Separate as much as possible the probe and digital input cables 
from the cables to inductive loads and power cables to avoid possible 
electromagnetic disturbance. 
Never run power cables (including the electrical panel cables) and signal 
cables in the same conduits
