9.4 To Activate the Filter
Monitoring Function
The filter monitoring can take place in two ways, by rating
or with a pressure sensor.
Rated filter monitoring is activated on delivery.
If filter monitoring with pressure sensor is required, it must
be activated for the filters that are to be monitored.
Rated (factory-preset)
The filters are calibrated at 60% and 90% of the motor
signal. The airflow and fan speed are read and are stored
for rating the filters’ calibration value. If the unit operates
above the 60% motor signal, the current airflow and the
fan speed are continuously compared to the calibration
values. If the current values are greater than the calibra-
tion value + preset alarm limit, an alarm is initiated.
With pressure sensor (optional under Service Level)
The pressure drop across the filter is continuously moni-
tored and an alarm will be initiated if the current pressure
is greater than the calibration value + preset alarm limit.

9.3.3 Downspeed Control of Fan Speed to Min. Set
Point, Airflow
Regulation of the supply airflow to a lower flow rate is the
last step in the regulation sequence on increasing heat-
ing load for ERS regulation. The extract air fan cannot be
selected alone; only the supply air fan or both the supply
air and extract air fans can be selected.
See Section 9.2 as well.
An adjustable temperature decrease allows a lower supply
air temperature setpoint, before down regulation begins.
This neutral zone can be set on line NZ SA DOWN REGU-
LATION in the appropriate menu.
