17.30.1 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.
Delay SAF
Start: 60 sec
Stop: 30 sec
Delay EAF
Start: 0 sec
Stop: 30 sec
17.30.2 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
17.30.3 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.
Outd.temp for
heat start: 3.0°C
Blocking of
1/1-speed: -10°C

17.30.5 Exchanger to 100% at start and alarm delay at start
To minimise the risk of freeze-up problems, the heat exchanger can be forced to maximum capacity
for the set time at start-up.
To eliminate the risk of, for example, fan pressure alarms at start-up, all alarm functions can be
suppressed for the set time.
