room unit. This value is not displayed if the corresponding fan parameter TypeControl =
‘ Press ‘.

Comfort , Economy (Pa, m3/h) – required duct pressure when controlling the
performance of the fans to constant pressure (VAV) or the required amount of air
conveyed when controlling the performance of the fans to constant flow (CAV) in the
regimes of Comfort or Economy . This value is only displayed if the corresponding fan's
TypeControl = ‘ Press ‘. The required and actual pressure or flow rate values in % are
passed to the PID–Regulation that controls the fans. The constant pressure (VAV) control
of the fans takes precedence over the constant flow (CAV) control. Therefore, for
constant flow control to apply, the required pressure must be 0 Pa.

PID–Regulation – the factory default values are: TI = 120 s, KP = 2, TD = 0 s. Only
displayed if the configuration parameter TypeControl = ‘ Press ‘.

Press (Pa) – displays the current duct pressure based on the analog pressure sensor if the
configuration parameter TypeControl = ‘ Press ‘.

Flow (m3/h) – displays the current air flow in the duct based on the analog pressure
sensor if the configuration parameter TypeControl = ‘ Press ‘.

RampStart (60 s) – time (ramp-up) for the fan speed control signal to reach from 0 V (0%
speed) to 10 V (100% speed). The ramp-up value is determined by the fan type and the
technical specification of the AC unit. The rump-up of the fan with EC motor is directly
controlled by the ramp value. The minimum speed of the EC motor is set in the controller
at 18 Hz. In case of fans with frequency converters, the ramp-up value set in the
controller is informative, because the fan start-up is determined by the ramp set in the
parameters of the frequency converter. Since the actual fan speed is not monitored by
default, the ramp-up value entered in the controller is mainly used to display the
expected actual fan speed. Therefore, the ramp-up values should be set the same in the
frequency converter parameters as in the controller. The minimum speed is also set in the
frequency converter parameters.

RampFinish (30s) – time (ramp time) for the supply and exhaust fan speed control signal
(each separately) to reach from 10 V (100% speed) to 0 V (0% speed). The ramp time has
a different value for every fan type. The run-out time of the fans with EC motors is
determined by this value. For fans with frequency converters, the ramp value is
informative because the run-out time of the fans is determined by the run-out time
