User selections 1 and 2 (cooker hood)
If the fire automation system has not been activated in the software, you will have access to both User selection 1 and User selection
2. If the fire automation system has been activated, you will only have access to User selection 1.
The user selection functions are used to override standard operation. The input signal must come from a potential-free contact. When
connection is established, the function with the settings that have been selected on the control panel under Service/User Selection is
activated.
The following are examples of situations when user selection functions are used.
Connection via Nilan Functional cable
Connection of User selection 1
A potential-free signal is connected to User selection 1 via the following:
1. Green/white
2. Green
NB: If fire thermostat/external fire automation system is not connected up, make a shunt between:
1. Green/white
7. Brown/white
Connection of User selection 2 (overriding the operation)
A potential-free signal is connected to User selection 2 via the following:
1. Green/white
2. Orange/white
NB: If fire thermostat/external fire automation system is not connected up, make a shunt between:
1. Green/white
7. Brown/white
Cooker hood
If you choose to run the cooker hood via the ventilation unit, the cooker hood will send a potential-free sig
-
nal to the ventilation unit when you switch it on. When this happens, the ventilation unit increases the air
volume to the set level, so that enough air is drawn through the cooker hood.
Fireplace/wood-
burning stove
Normally, ventilation is balanced with slightly negative pressure in the dwelling so that dampness is not
pressed into the building components. This, however, is a disadvantage if you light a fire in your fireplace/
wood-burning stove as the smoke will then enter the dwelling instead of being drawn out through the
chimney.
When lighting a fire in the fireplace/wood-burning stove, you can activate the user function with a
potential-free contact that ensures positive pressure in the dwelling. Smoke is then drawn out of the
chimney as intended.
Prolonged
operation
If the ventilation unit is used in an office or a school where ventilation is reduced outside opening hours, it
may be necessary to increase ventilation temporarily if the building is used in the evening for, for instance,
meetings.
In that case you can have a potential-free contact that is activated, causing ventilation to increase, for
example for an hour, before operation ceases again.

If you are not using the Cooker hood setting in User selection, you will be able to use any RJ45 cable. In that case, wire 8
Brown will not carry 12V.
