type Length Flags
Forced operation, 2-bit Channel X – General DPT 2.001 2 bit C W
This group object is used to activate/deactivate 2-bit forced operation via the bus (ABB i-bus® KNX),
Forced operation is activated/deactivated with bit 1. Bit 0 is used to toggle between the states
Forced operation active "ON" and Forced operation active "OFF" .
If forced operation is active, the control value cannot be controlled via KNX commands.
Telegram value (bit 1 | bit 0):
•
0 | 0 = Forced operation inactive
• 0 | 1 = Forced operation inactive
• 1 | 0 = Forced operation active "OFF"
• 1 | 1 = Forced operation active "ON"
