16.28.1 Start and stop delays for the fans
Use start delay if you wish one of the fans to start before the other and for example if
you wish to give the close-off dampers time to open before starting the fans. Use stop
delay e.g. to create a cool-down period when using electric heating. In order to avoid
letting in too cold air, e.g. in the winter, the heat exchanger will continue to run during
the stop delay.

Start: 60 sec
Stop: 30 sec

Start: 0 sec
Stop: 30 sec
16.28.2 Retardation time
When switching two-speed fans from 1/1-speed to 1/2-speed there is a settable
retardation time. The same time applies to both fans.
Retardation time
1/1-1/2speed: 10 sec
16.28.3 Heating at start-up and high speed blocking
At outdoor temperatures below the set value, the heating output will be forced to 100%
before start-up.
Two speed fans and pressure controlled fans can be blocked from using high speed at
outdoor temperatures lower than the set value. This function should not be combined
with the function
’’Outdoor compensation of pressure setpoint’’. See the section
Demand control.
Both functions need an outdoor temperature sensor.
