Chapter 11 Air control
Pressure control SAF and EAF
Pressure control can be set in pascal (Pa) or in inch water gauge (in.wg). A factor (x100) is used in
the program and displays when the unit is set to in.wg.
When using pressure or flow controlled fans, the setpoint can be temperature compensated.
The compensation has the default value 0 Pa, i.e. no compensation is added. The compensation is
linear between the setting points. The compensation can be positive or negative.
The same compensation normally applies to both fans. Using E tool

, you can choose to
compensate only the supply air fan.
The same compensation is applied to both "Normal" and "Reduced", which means that you need to
take caution when using this function so the pressure does not become too low or even negative
when running reduced speed.
Depending on the choice of fan control, different combinations of the menus below will be shown.
Pressure control SAF (there are corresponding menus for EAF)
