Block Shading Block Shading| Block function block for the control element Block Shading, the control element must be linked with this function block. See Block Presence and Presence General. |
The starting point for shading is the calculated sun position. Once it is reached, the shading moves to the on position. In addition, brightness and temperature can also be taken into account. The shading then moves to the on position when all conditions are met, and to the off position when the conditions are no longer met.
Inputs |
||
| HE |
Brightness |
Brightness (optional) |
| TM |
Temperature |
Room temperature (optional) |
| SP | Lock | Optional. Lock: not equal to 0 locks, 0 releases. While locked, the shading does not move; what happens when the lock is set is defined by the parameter Lock action. Not connected: never locked. |
Outputs |
||
| ST |
Status |
Status output for display on the
control element. The value is bit-coded: Bit 0 = Status Active Bit 1 = Status Locked Bit 2 = Status Shading active Bit 3 = Status Sun position reached Bit 4 = Status Brightness limit reached Bit 5 = Status Temperature limit reached |
| SH |
Sun
height curr. |
Calculated sun height (elevation) |
| SW | Sun angle curr. | Calculated sun angle (azimuth) |
| H1-X |
Height |
Setpoint height 1 |
| L1-X |
Slat |
Setpoint slat 1 |
Parameters |
||
| Number of
outputs |
Number of roller shutters | |
| Longitude |
Longitude in decimal degrees for
calculating the sun position |
|
| Latitude |
Latitude in decimal degrees for calculating the sun position | |
| Action on inactive | What happens when the shading is switched from Active to Inactive in the control element. No action (default): the blinds stay where they are. Move to position off: the blinds move once to the position for the end of shading (Inactive) – not while the lock is set. | |
| Lock action | What happens when the lock is set (change at the input Lock from 0 to not equal to 0). No action (default): the blinds stay where they are. Move to position off: the blinds move once to the position for the end of shading (Inactive). | |
