Sensor allocation:
Sun sensor allocation is used to set which sun sensor the function should
listen to. The system can have two sun sensors connected and therefore the function can use
either one of them or both at the same time. You can allocate differently for each zone.
Remember that on and off delay is not only connected to the suns behaviour, they are
also connected to temperature changes, but normally temperature is changing less
rapidly compared to the sun. The Get heat function can only be active in Automatic
mode.
This function requires an outside temperature and sun sensor/s. The sun sensor
allocation in this function is completely independent from the Sun function’s sun sensor
allocation.

The timer range is normally set during non working hours to avoid glare when the
building is occupied.

Preserve heat
About:
The Preserve heat function is used to preserve heat inside the building by
using the solar protection to improve the window’s insulation and hence help the
heating system in the building. Enable this function for each zone by selecting Yes in
the “use function” parameter.
Active:
This function has two criteria in order to get active. (1) When the outside Temperature
is lower than the function’s outside Temperature threshold AND (2) the Timer range is between
Start and Stop time THEN the solar protection will be commanded down.
The Timer span is normally set during non working hours to ensure, when the building
is occupied, visual contact with the outside through the windows. This function is
mainly used during nights.
Adapt the function:
First set the Timer’s time span (Set timer) for each zone for when this
function can be active. If you feel that there is a possibility to save more heat then increase
Temperature threshold. If you feel that the function is activated a bit too slow then decrease the
