Building Technologies Fan speed controller, demand-controlled (basic type P) 03.10.2011
Variant with constant room overpressure control
Setting values must be adapted accordingly, if the extract air fan is implemented as
constant room overpressure control (e. g. pressure setpoint = 25 Pa, setpoint
reduction = 0 Pa etc.).
The rate at which pressure setpoints or speed are optimized is defined via the
"Control action" setting parameter.
In addition, you can also define how to evaluate the collected damper positions.
 Maximum: Only the highest damper position is considered for setpoint
compensation.
 Average: The average of all damper positions is considered for setpoint
compensation.
