Danfoss Eco
Safety precautions
Tested for safety and EMC requirements as specified in EN 60730-
1, EN 60730-2-7, EN 60730-2-9, EN 60730-2-14, EN 61000-4-2 , EN 
61000-4-3 and RED directive.
UK NOTE: The optimum performance comes when the Danfoss 
Eco™ is mounted in the flow of the radiator. Danfoss Eco™ can 
also be mounted in the return as long as the radiator length is 
less than 1.6 meter.
The thermostat is not intended for children and must not be 
used as a toy. Do not leave packaging materials where children 
may be tempted to play with them, as this is extremely danger-
ous. Do not attempt to dismantle the thermostat as it contains 
no user-serviceable parts. If error code E1, E2 etc. is shown in the 
display or other defects appear, please return the thermostat to 
the distributor.
