Parameter Range Function
Actual Value xx [l/s], [Pa] Depends on control type (fan control mode), e.g. present value of
pressure.
Controller 0…100 [%] Present value for the controller. Go to page with all controller set-
tings.
Output signal 0…100 [%] Present value for output. Go to page with all analog output set-
tings.
Command – Off
– Stage 1
– Stage 2
– Stage 3
Present state of fan. Go to page with all digital modulating output
settings.
Fdbk – Alarm
– Ok
Condition: Master Index > Configuration > Configuration 2 > Fan
fdbk <> No.
Present value of the feedback. Go to page with all digital input set-
tings. For example, you can set the time for jitter protection (De-
fault: 5 s).
Alarm – Ok
– Alarm
Condition: Master Index > Configuration > Configuration 2 > Fan

Alarm – Ok
– Alarm
For supply air fan only!
Condition: Master Index > Configuration > Configuration 2 > Fan
alarm <> Combined.
Present alarm state for both fans. Go to page with all digital input
settings. For example, you can set the time for jitter protection (De-
fault: 0 s).
