Supply chain VAV overridden value (SplyVavOvrr11)

Overview

The application function "Supply chain VAV overridden value 11" (SplyVavOvrr11) allows a technician / balancer to override the VAV applications for balancing and commissioning of the ductwork.

Function

The technician overrides VAV damper position and VAV flow setpoints via SplyAir group distribution to the destination object. See Engineering and commissioning.

Engineering and commissioning

The function can be enabled for supply and extract separately.

The priority for overriding is Prio 8.

MP1.2 and higher:
Use EnVavSuModOvrr and VavSuModOvrr (DeviceMode Multistate)

1:Off
2:Control mode
3:Maximum air volume flow
4:Minimum air volume flow

MP1.16:
Use EnVavSuOvrr and VavSuOvrr [% of nominal flow]

Example: PL-Link VAV, mapping will go to the AO for the flow setpoint
Range 0..100% of Nominal Flow
