Fans
On the EC tower, a fan can be individually controlled.
The parameters “DTC start” and “DTC range” are related to the differential temperature
control. The differential temperature control is not active for the EC tower.
Reduction according to temperature
Enter the start temperature as a negative difference to the air temperature setpoint. ➊
Enter the start speed as a percentage of reduction of the maximum speed. ➋

7.2.2 Air circuit, internal standard components
The speed lowers proportionately with
a sinking air temperature up to the start
speed if the set temperature difference ➊
under the temperature setpoint is reached.
However, if the heater or humidification is
requested, the speed is raised to its original
value.

Filter alarm time delay ➍
Monitoring the pressure drop of an in-
ternal air filter
You can set a maximum value ➎ for an
analog differential pressure monitor, which
monitors the pressure loss via the prefil-
ter. An alarm is generated if the value is
exceeded.
To correctly assign the differential pressure
monitor, you must configure the sensor with
the sensor purpose 24, 25 or 26.
