EM-box (damper solution)
The system works as follows:
When you switch on the cooker hood, User selection 1 or 2 will be activated. The ventilation unit increases ventilation and sends an out-
put signal to the EM-box that it is to close the damper for extraction from other rooms. However, the damper does not close completely
and a reduced level of air extraction from other rooms will still take place.
When balancing the damper, the small stop blocks on the damper must be positioned so that the basic ventilation rate is maintained
from the other rooms.
The EM-box damper option it easy to connect up to Nilan’s CTS602 Connection Box.
If you want to run the cooker hood via the ventilation unit, there may be times
when the air volume is insufficient for cooker hood extraction.
If you install an EM-box, you can regulate the extracted air when the cooker hood
is in operation, so that less air is drawn from, for instance, the bathroom and the
utility room. This will allow enough air for the cooker hood to extract sufficiently.
The EM-box is fitted with a metal filter that cleans the air in the cooker hood of
grease particles efficiently. It thereby protects the ventilation unit.

ATTENTION
Information on connecting User selection output and GND can be found under: CTS602 Connection Box.
NB: Wire for 230V power supply for the EM-box damper is not included.
ATTENTION
If you want to connect the EM-box together with a Fire automation system, you can find a solution in the section about
“Connection box for user selection and EM-box” in the chapter “Fire automation system”.
