NTC - Carrier Room Controller 2
GB - 2
In the Occupancy mode and according to the CRC2 configuration
and system type (Communicating or stand alone), different icons
will switch on. The figure below shows the display when the MODE
button is pressed, by starting from the OFF mode:
• Stand Alone system during heating
• Display the desired user temperature through two digits (25°)
• Louver operation: fixed position 2
• Ventilation speed: Auto
Communicating system
• Display the room temperature (22°). The temperature required
by the user is reached.
• Louver operation: Swing
• Ventilation speed: Minimum
Changing the desired temperature
The desired temperature can be changed by means of the UP and
DOWN keys. Temperature is shown either by the bar-graph or the
two digits or even both.
Communicating system
The communicating system offers two options, which can be set
from the configuration menu:
• Desired temperature displayed by means of the bar-graph
only (fig. 1)
• Desired temperature displayed by means of the bar-graph and
numerically (fig. 2).
fig.1
fig.2
An option in the configuration menu also offers the possibility to
select the temperature by choosing the value of one step:
• 0 ºC
• 0,5 ºC
• 1 ºC
• 2 ºC
In the first example, each time the UP or DOWN keys are pressed,
temperature increases or decreased by 1 degree.
Each time you press the UP or DOWN keys, one segment in the
bar-graph is coloured. If no key is pressed, the coloured segment is
the one in the middle, which corresponds to the temperature of
22°C (72°F). Starting from this value, we will show you how the
display changes when the UP key and then the DOWN key are
pressed until reaching the maximum and minimum temperature
value.
This example also shows how to use the second temperature range
where a single pressure of the UP and DOWN keys results in a
temperature increase or decrease by 2 degrees.
General information
• Pay special attention to maintaining a comfortable room
temperature above all for children and elderly or disabled
persons.
• For correct use the conditioner must only operate at the
temperatures indicated in the “Configuration” table in the
installation manuals of the outdoor and indoor units.
If the unit is made to operate beyond these limits faults or
water leaks may occur.
• Make sure the Room Controller control unit has not been
damaged in transport; if the opposite is true file an immediate
claim with the shipping company.
• Only use the appliance for the purpose it was designed.
• Dispose of packaging material in accordance with local
requirements.
• Do not open the appliance otherwise it may suffer damage. In
case of malfunctioning, contact a qualified service engineer.
Characteristics
The air conditioning system is managed by a centralised
system which runs the air conditioner daily in “Comfort” mode
during the hours it is expected that there will be persons in the
room and in “Economy” mode during the remaining hours.
The individual and personalised adjustment of the temperature
and operating mode is possible at any moment.
