Open-window function
Danfoss Eco™ features an Open-window function,
which closes the valve if the room temperature is
falling dramatically, thus reducing the heat loss.
before Danfoss Eco™ returns to its original
settings. When Open-window has been activated,
the function is quarantined for 45 minutes.
Adjusting to the valve
During the first night of operation Danfoss Eco™
will shut off the radiator heat and then open
again to detect the exact opening point of the
valve. This will allow Danfoss Eco™ to control the
heat as efficiently as possible. If necessary, the
procedure is repeated once a night for up to a
week.
You might experience the valve being warm
during the adjustment procedure, regardless of
the room temperature.
Child lock
Activating the child lock feature will protect the
settings from tampering.
Adaptive learning
During the first week of operation Danfoss Eco™
learns when it is necessary to start heating the
room in order to reach the correct temperature at
the correct time.
The intelligent control will continuously
adjust the heating time compared to seasonal
temperature changes.
Automatic valve exercising
To keep the radiator valve functional and at its
best, Danfoss Eco™ automatically exercises the
valve every Thursday at appro
x. 11:00 hrs by fully
opening and then returning to its normal setting.
Measuring the room
temperature
Danfoss Eco™ is measuring the temperature
with multiple built-in sensors to ensure accurate
control. Based on these readings the room
temperature is calculated for an area approx.
20cm in front of the display. This allows Danfoss
Eco™ to control the actual room temperature very
accurately.
Be aware that sources of cold or heat, e.g.
fireplace, direct sun or draft, might affect the
function of Danfoss Eco™.
