WARNINGS

CAREL 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 and its subsidiaries 
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 may, based on specific agreements, acts 
as a consultant for the positive 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 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 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 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 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 product portfolio.
CAREL adopts a policy of continual development. Consequently, CAREL 
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 in relation to its products is specified in the CAREL 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, its employees or subsidiaries 
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 or its subsidiaries are warned 
of the possibility of such damage.

DISPOSAL

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.

Warranty on the materials:
