5.3 Damper control
5.3.1 General
Dampers are enabled in configuration 1, configuration 2 and configuration I/Os,
preconfigured and the inputs, outputs defined.
Main Index > Configuration > Configuration 1
Parameter Range Function
Damper – No
– Combined
– Supply
– Supply+Exh
– No opening/closing of dampers.
– Two dampers with common output.
– Outside air damper with output.
– Two dampers with separate outputs.
Fire damper – No
– Yes
– FollowUnit
– No fire dampers.
– Fire dampers.
– Fire dampers are opened with Unit Start or
closed with Unit Stop.
Main Index > Configuration > Configuration 2
Parameter Range Function
Damper fdbk – No
– One
– Two
– No damper feedback.
– Feedback for outside air dampers (or a common
feedback for both dampers).
– Separate feedback for outside air and exhaust air
damper.
Fire damper fdbk
– Closed
– Clsd+Opnd
– Combined
Fire damper feedback.
– Only one feedback for close.
– Two separate feedbacks for open and close.
– Two feedbacks for open and close, but only one
signal. The syntax must be correct:
1 (close) ---> 0 (moving) ---> 1 (open)
Main Index > Unit > Damper Control
Parameter Range Function
Off delay by fanoff 0…36000 [s] Switch-off delay for outside air, exhaust and fire
dampers. The dampers are closed after this period
after switching off the supply air fan.
