Measuring fan Mode 1
In this operating mode the volume
fl
ow is controlled exclusively by the fan speed.
A throttle shutter is controlled classically primarily dependent on the stall temperature with the
responsible shutter regulators (offset shutter, control range shutter,
…
). The factory values are
recommended for these settings.
In order to achieve a minimum air rate when the shutter is to be closed according to the temperature,
the shutter opening must be linked additionally to the ventilation regulator. The parameter
“
ventilation
link
”
enables this by linking the shutter opening to the control of the ventilation regulator. The 30 %
setting therefore means that the throttle shutter is fully open at 30 % control of the ventilation regulator
(that is a set fan speed of 30 %).
