Description
Factory setting and
(max. / min values)
EB - Fan speed levels
EB3 - Level 3 Supply air
is typically configured to a level with high
activity in the house
EB 4 - Level 4 supply air
is typically configured to 100 % airflow
for a quick replacement of air in the entire house.
Remember that a higher air exchange rate increases energy
consumption.
EB5 - Level 1 Extract air
The fan speed is adjusted until the same air flow is achieved as the
supply air on level 1.
EB6 - Level 2 Extract air
The fan speed is adjusted until the same air flow is achieved as the
supply air on level 2.
EB7 - Level 3 extract air
The air flow of level 3 is adjusted to the same air flow as the
supply air on levels 3 .
EB8 - Level 4 Extract air
The fan speed is adjusted until the same air flow is achieved as the
supply air on level 4.
EB9 - Fan mode
Use % if no built in airflow sensors have been connected.
Fanspeed input EB1 to EB9 will be based on % of max capacity.
Choose m3/h as option for constant airflow control.
Please note that this requires built in airflow sensors in the
airhandling unit.
Please be aware that using this function without airflow sensors
will lead to corrupted airflows.
Please note that fans will automatically adapt to increased
pressuredrop (for example clogged filters) to maintain a constant
airflow - in this case increased fan power consumption is expected.
When selecting m3/h EB1 to EB9 will automatically allow direct
setting of desired airflow in m3/h. Be aware that m3/h setpoints
need to match capacity of MVHR unit.
EB10 - RPM Alarm
Off
= RPM feedback from fans are not used actively
On
= If RPM feedback from fans reach 0 and fans are expected to
run , the MVHR unit will shut down and show alarm.
EB11 - Reset RPM Alarm
Activate this function to reset RPM alarm once the problem has
been fixed
