- DIP switch 4 is used to change output of Y10 from DC 0...10 V to DC 10...0 V
- DIP switch 5 is used to change the valve output from On/Off to 3-position

Applications with supply and extract air
Applications with supply and extract air can be realized in the following ways:
∂ Control signal from RDG.. and VAV air damper position (for primary air
optimization) are transmitted via KNX bus
∂ Communication settings (geographical zone, air distribution zone) of the RDG..
and the GDB..KN need to be set accordingly.
Reference see [18] and section 3.10.13.
∂ This application requires VAV compact controllers with KNX LTE-Mode
∂ RDG.. output Y10 controls both VAV compact controllers for supply air and
extract air
∂ The current air damper position of one VAV compact controller is transmitted to
input U1 and via KNX for primary air optimization
∂ This application requires analog VAV compact controllers (noncommunicating)
