Amplif. 20 amplification. The higher the
amplification, the quicker the
controller will respond, but
the greater will be the risk of
oscillation. The lower the
amplification, the slower the
controller will respond, but
the lower will be the risk of
oscillation.
Alarm limit Pressure fluctuations within
Δ Pa ±70 Pa the Δ Pa alarm limit setting
will not activate an alarm.
Alarm limit An alarm is activated if

exceeds the Δ Pa alarm limit
setting for longer than the
min. duration setting.
