User Selection 2; Em-Box (Damper Solution) - nilan Compact P2 Installation Instructions Manual

User selection 2

User selection 2 offers you the same options as User selection 1. In addition, you get the option of a relay output that can control e.g. a
damper or whatever external function you may need to control.
The 8-pin plug and the terminal block are located at the top of the unit. You create the connection to the terminal block on the back of
the cover plate. You then run the wires through one of the cable glands.

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 regu-
late the extraction so that less air is extracted out of the other rooms, e.g. ba-
throom 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 selection 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.
The EM box is connected to the 8-pin plug. Pin 2: User Selection 2 and Pin 4: GND. The relay output is connected in the 6-pin terminal
block. Terminal 4: User selection 2 (Output) and Terminal 5: N (Output) as shown in User selection 2.
