the batteries run out. Before the batteries run out Danfoss Eco™ will
leave the valve in Frost Protection position to protect the heating
system from damage. Estimated battery life time is up to 2 years.

1.9 Automatic adjustments
When Danfoss Eco™ is installed it will automatically begin to adjust itself to your heating
system, during the first week after insallation. During this process you might experience that the
thermostat reacts slowly or turns the heat up and down by itself. This is normal and a necessary
part of the adjustment process.
1. 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.
2. Adaptive Learning
If you activate Adaptive Learning Danfoss Eco™ learns during the first week of operation 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.
Using Saving Program requires that your heating system has enough heat for a short period
during heat up. If you experience problems you should contact your installer.
Short press on and the Display Screen appears.
