This function requires an outside temperature sensor. The
Preserve heat function is active
only in Automatic mode.
Using exterior solar protection: If there is any risk that the solar protection can
“freeze”, an exterior thermostat should be connected to e.g. the system’s external
lock input/s. The set point should be set just above the freeze point. Contact your solar
protection supplier for more consultation.

About:
The Sun function is used to command the end products to specific position
when there is sun. Using this function helps to avoids over heating and glaring
situations inside the building. Sun function can only get active in Automatic mode.
Enable this function for each zone by selecting Yes in the “use function” parameter.
Active:
This function gets active when the sun intensity exceeds the On threshold for a certain
time period (On delay) and the solar protection will go down. When the sun intensity is lower
than the Off threshold for a certain time period (Off delay) then the function gets inactive and
the solar protection will be commanded to up position.
