Cold draught protection
Why cold draught protection?
The protection against cold draughts is used to increase comfort
and to prevent uncomfortable draught from occurring, for
example, by windows and glazed sections.

How is cold draught protection
regulated?
If there is a radiator in the room this can be used as cold
draught protection. The function can be used for both Occu-
pancy and Unoccupied modes in a room. When the cold draught
protection is enabled, the radiator is turned on set to a precon-
gured level that is not fallen below. The radiator turns o if
the cooling requirement is higher than a congured level, or if a
window is opened.
Frost protection
Why frost protection?
Frost protection ensures safety, it counteracts the freezing of
water in pipes and it counteracts moisture from permeating the
building.
How is frost protection regulated?
If there is a product in the room that can heat, the frost protec-
tion function will be enabled at the set limit. This function opens
the heating valve or enables the electric heater to 100% when

the room temperature is lower than the temperature limit. The
protection’s temperature limit is possible to set between +5°C to
+15°C. The frost protection control is always used, irrespective of
the operating mode. The frost protection is also enabled if there
is an open window.
The factory setting is set to +5°C. A temperature sensor or
product with integrated temperature measurement is needed
in the room for this function. Heating can come from comfort
modules or electric/water radiators.
Open window
Why detect open windows?
Energy savings can be achieved by detecting open windows as
unnecessary cooling and heating are prevented. In warm and
moist weather conditions condensation problems can also occur
in the rooms when cooling is installed and a window is open.
What happens when an open window
is detected?
If a window is opened the heating/cooling valve closes to save
energy and avoid problems with condensation. The frost protec-
tion function ensures that the products are not damaged by
heating if the temperature is below a congurable value (stand-
ard value 5°C).

Air ow Extract air 100 0 100 % Installation/Installation Extract air ow if there are open windows.
Operating case
If WISE WCS detects that a window is open, the supply air ow’s
setpoint value is set to min. It is possible to congure how the
extract air should act in the event of an open window. The
extract air ow is congurable between 0-100%.
It is also possible to set a switch-on delay to Open windows,
which means the supply air and extract air ows are not
adjusted until aer the set time. For example, this can be useful
if the Open window function is used for a door that is frequently
opened and closed, where you do not want the air ows to be
adjusted directly when the door is opened.
