EM-box (damper solution)

If it is desired to run the cooker hood over the ventilation system, it may in some cases be difficult to get enough air for the cooker hood.
With an EM box installed and when the cooker hood is in operation, you can regulate the extraction so that less air is extracted out of
the other rooms, e.g. bathroom and utility room so that there is enough air for the cooker hood to extract sufficiently.
The EM box is equipped with a metal filter that effectively cleans the cooker hood air of grease particles, as extra protection for the
ventilation unit.
The system works as follows:
When the cooker hood is switched on, User programe 2 is activated. The ventilation unit increases the ventilation and at the same time
sends an output signal to the EM box that it must close the damper for extract air from the other rooms. However, the damper does not
close completely in, there will still be extraction from the other rooms, just reduced.
When balancing, the small stop blocks on the damper must be set so that the basic ventilation is maintained from the other rooms.
