NTC - Carrier Room Controller 2
Operation
Flow direction (where applicable)
In some units, the air flow direction can be controlled by means of
special wings known as louvers.
To set their position when the CRC2 is in the Occupancy mode,
keep the FAN key pressed for at least 5 seconds:
The present position of the louvers is displayed by the two digits
on the CRC2 display. To change it press the UP or DOWN keys
within 10 seconds or the CRC2 will automatically quit the menu.
To confirm your choice, press the FAN key.
The CRC2 will quit the configuration menu. The following values
can now be set: Auto (Au), Swing (S_) and the 6 fixed positions
(1,2,3,4,5,6). Remember that the 6 fixed positions cannot be
displayed by means of the louver icon.
Operation examples starting from any Occupancy mode:
GB - 4
5 sec.
AUTO position (Au):
The unit will automatically select the best position of the louver
according to the required operating mode.
SWING position (S_):
In order to ensure a constant distribution of air, in this mode the
louvers will constantly move from the bottom upwards.
NOTE:
If several units are connected, the louver setting will be transmitted
to all units.
To access to the configuration menu read the CRC2 installation
manual.
Important:
If you do not think that anyone is going to be in the room
for several hours, we advise positioning the control to the
OFF position (Frost protection).
An energy saving will be obtained in this way which will be
translated into an economic saving.
