Application Guide Heating Control Danfoss Ally™
2.2 Functions
Danfoss Ally™ Radiator Thermostat has a built in function that senses if a window has been
opened. It will automatically shut o the heat for 30 minutes, after which the heating
intheroom will automatically be restarted. If you have more than one radiator inthesame
room, only one of the thermostats has to register an open window, after which all the radiators
in the same room will shut o.
Please note:
• The radiator must be located in the immediate vicinity of the window (which it most often
will). If the radiator is located e.g. 10 meters from the window, it may be dicult for the ther-
mostat to sense a clear drop in temperature, which is needed for it to turn o the heat.
• Between the nish of the “open window” period and the start of a new one there must be at
least 45 minutes.
• The rst activation of the “open window” feature is 75 minutes after the battery insert.
• If you live in a home without a ventilation system, we recommend that you ventilate the
entire house twice daily for a minimum of 5 minutes by opening windows in opposite ends
of the house.
• If you have a Danfoss Ally™ Room Sensor
installed, the open window function will be
disabled. The Room Sensor cannot detect that
a window is open and the system will continue
the heating process
The pre-heat function ensures that the comfort
temperature is reached at set time. The warm
up time is continuously adjusted according
toseasonal temperature changes.
• Pre-heat function ensures that the wanted temperature is reached at the wanted time (here
20°C at 07:00).
• Pre-heat uses data from the previous 7 days to be able to reach the correct temperature at
the right time.
