Presetting the priority of sun protection
The priority of the sun protection function can be set separately for each output. In the simple sun
protection, the priority relations between the "Sunshine / shading facade" object and the objects of direct
operation (short-time, long-time, central or position telegram, scene recall) must be configured.
For the sun protection parameters to be visible, the sun protection function must be enabled on parameter
page "Ax – Enabled functions (x = number of output).
Set the parameter "Priority of sun protection with respect to direct operation" on parameter page "Ax -
sun protection" to "same priority".
The sun protection mode can be overridden at any time by direct operation. In the same way, the sun
protection overrides the direct operation, when a new "sunshine" telegram is received via the "Sunshine /
shading facade" object and when a parameterized time delay, if any, has elapsed. If the sun protection
function is overridden by a direct operation, the preset behaviour "Reaction at the end of sunshine /
shading" will not be executed.
Set the parameter "Priority of sun protection with respect to direct operation" on parameter page "Ax -
sun protection" to "higher priority".
An active sun protection will override a direct operation. The sun protection mode can therefore not be
interrupted by a direct operation. Direct operation will be possible again only after the sun protection
function is terminated.
Set the parameter "Priority of sun protection with respect to direct operation" on parameter page "Ax -
sun protection" to "lower priority".
A direct operation can at any time override the sun protection mode. If the sun protection function is
overridden by a direct operation, the preset behaviour "Reaction at the end of sunshine / shading" will not
be executed. The sun protection function can only be reactivated after an enabling movement controlled
by a direct operation has been effected and after a new "sunshine" telegram has been received via the
"Sunshine / shading facade" object. If the enabling movement has not yet occurred, any attempt to
activate the sun protection will be disregarded.
Enabling movement:
An enabling movement is an accomplished long-time travel movement into the upper end position which
has been initiated by the objects "Long-time operation" or "Central travel control" A manual control, an
upward travel movement after bus voltage failure or bus voltage return, a position approach to "0 %" or
an upward travel movement after releasing enabling of forced-position or safety functions have no
enabling effect.
The sun protection is not enabled if the enabling movement has been interrupted. The sun protection
function will be also be interlocked, if the output has been re-adjusted again by a direct operation after an
accomplished enabling movement.
After an ETS programming operation or after switch-on of the supply voltage (bus and mains voltage) the
sun protection function is generally enabled.
Manual local operation on the device itself, the forced position function and the safety functions have a
fixed priority higher than that of the sun protection. The sun protection is overridden – but not terminated
– by a function with a higher priority. After the end of the function with the higher priority the reaction at
the beginning of sun protection will therefore be executed again, if the sun protection is still active at this
time.
With the settings "same priority" or "lower priority", the sun protection can be overridden by a direct
operation only if the direct control action can be executed at once. A direct operation will therefore not be
able to override the sun protection during a manual control locally on the device, an active forced position
function or an active safety function.
Parameter setting "same priority" or "lower priority": A variable preset of curtain and slat positions or of a
slat offset via the bus at the beginning of sunshine / shading shows no reaction at the output, if the sun
protection was overridden by direct operation. However, the position data or offsets received are stored
internally so that the new positions will be approached on reactivation of the sun protection.
