8.8 External high speed (time delay)
The function gives time delayed reset to low speed when
the input for external alteration between High speed and
Low speed shifts.
The time can be set 0:00 – 3:59 which is the time in hours
and minutes. 0:00 gives that the function is not activated.
Use: for instance prolonged operation with button or re-
operation time together with presence sensor.
8.9 Closure = High speed or Low speed
Here can be chosen if the external alteration HS/LS shall
give High speed or Low speed at closed contact. Closure
= Low speed shall be chosen at i e presence sensor. If the
contact is not used "Closure = High speed" shall be
chosen (factory set).
The external contact only influences when the internal
switching clock calls for Low speed.
8.10 Time filter test
Set the start time for filter test (0.00–22.59). It shall be set
on the time when the least inconvenience for the user is
at hand, as the unit both is stopped and operates on filter
test flow regardless to what flow is chosen. Factory set
value is 22.59.
While External Stop is activated, no filter tests are
done. The filter test can be done if the aggregate is
running at low or high speed. Low speed can be set to
0 l/s, i.e. shut-off but still active. The filter test cannot
be done on a manually stopped aggregate.
8.11 Filter test
At filter test, the unit is operated up to filter test flow and
one of the pictures to the right is shown. The flow is
stabilized after ca 1 minute.
FILTER STATUS NOW shows the degree of pollutions for
each filter and ALARM LIMIT shows what level of
pollutions that provides a filter alarm. 10 units
corresponds to recommended final pressure drop across
the filter.
The limit can be set between 0 and 99. The factory set
value is 10. This causes the rpm of the fan to increase
approx. 5% from clean filter until alarm is shown.
8.12 Anti-freeze guard function
When water coil with anti freeze guard function is
connected it is determined if the anti freeze guard
function with heating of the water coil shall be activated
or not (activated = 1). The function is keeping coil warm
to 12°C at operation and to 25°C at stopped unit.
If the function is chosen and no sensor is connected, an
alarm is obtained.
