Wake up the thermostat

Danfoss Icon™ Programmable is designed to blend in with any interior. When not in use, the display turns off and becomes virtually invisible.

When the screen is touched, the display comes to life instantly and displays the current room temperature for two seconds, then switches to Home Screen.

The Heating icon is displayed, if the thermostat has turned on the heat.

The Cooling icon is displayed, if the thermostat has turned on the cooling (only if cooling is enabled in your system).

The Home Screen

On the Home Screen the icon for active mode is fully lit, e.g. At Home .

Icons for inactive modes are dimmed down, but still visible.. Activate another mode by touching the icon.

If no icon is touched, the screen will go to sleep after ten seconds.

Home Screen icons

At Home: Touch icon to set temperature for the At Home period (your comfort temperature).

Away: Touch icon to set temperature for the Away period (your economy temperature).

Asleep: Touch icon to set temperature for the Asleep period (your comfort temperature at night).

Settings: Touch icon to choose program and change settings.

How to use Danfoss Icon™ Programmable

Recommendations on set-back temperatures

Danfoss Icon™ Programmable is easy and intuitive to use:

•You change value with or .

•You scroll between menus and programs with or .

•You confirm with . The screen is flashing shortly to indicate that the new setting is active.

Forecast feature

Danfoss Icon™ Programmable has an automatic Forecast feature, where the thermostat during the first two weeks adapts itself to the characteristics of the room.

It means that Danfoss Icon™ Programmable learns when to start heating up in order to reach the desired At Home temperature on time (re-heating times can be very different from room to room).

This is especially important with underfloor heating in heavy floor constructions, because the floor concrete need to be heated, and it takes time.

Example:

Program P4 is chosen.

Away temperature from 09:00 is set to 18° C.

At Home temperature from 17:00 is set to 21° C.

21°

18°

09:00

17:00

15:20

Forecast says: Start heating now!

The Forecast feature has learned that heating must start up at 15:20 in order to reach the At Home temperature of 21° C at 17:00.

For a traditional heavy floor heating system with pipes embedded in concrete, Danfoss recommends Away and Asleep (set-back) temperatures a few degrees lower than the At Home (comfort) temperature. A larger temperature difference will be “overruled” by the Forecast feature.

With a light (dry) floor construction cooling / heating time is shorter, and you might choose a larger temperature difference.
