Used together, the X-AIRCONTROL Zone Module and the
X-AIRCONTROL Room Panel are capable of controlling temperature
and ventilation as a stand-alone system. These instructions describe
the relatively simple procedure for setting up the system and provide
a description of each function in the settings menu.

X-AIRCONTROL CP/2T Room Panel
DESCRIPTION
By combining an X-AIRCONTROL Module with an X-AIRCONTROL
Room Panel, temperature and ventilation air flow can be controlled
without any communication to a central air handling unit. This can
be convenient when, for example, one or more cabins are located
away from the main building. The system can be configured directly
from the Room Panel touchscreen. Although the Room Panel has a
built-in room temperature sensor, additional sensors can be added
either to the Zone Module or directly to the Room Panel.
The Zone Module comes in three different variants; all are equally
capable, but each is intended for a different VAV communication
interface. The X-AIRCONTROL Zone Module Analogue uses mainly
0-10V signals. There are also two digital versions, communicating
with Modbus and MP-Bus respectively.
All versions use Modbus to communicate with the Room Panel.
MOUNTING
Mounting the X-AIRCONTROL Zone Module
The X-AIRCONTROL Zone Module is designed to be mounted on a
DIN rail. Avoid direct exposure to sunlight. After initial setup, there is
no need for physical access to the X-AIRCONTROL Zone Module
and the unit can therefore be mounted in concealed locations. Note
though that the cable from

the X-AIRCONTROL Zone Module to the Room Panel must not
exceed 50 m (164 ft) in length.
Mounting the X-AIRCONTROL Room Panel
The Room Panel is designed for flush mounting in a hollow wall box.
Use a standard EU size flush mounting box with an installa-tion
opening of 60 mm. A minimum depth of 22 mm is needed. Do NOT
position the Room Panel in direct sunlight or draughts.
CONNECTING
For a description on how to connect various sensors, please refer to
the instructions for the X-AIRCONTROL Zone Module concerned.
Connecting the Room Panel
The Room Panel is connected to the Zone Module by means of a
Modbus cable (straight, no cross-over).

CONFIGURATION
The system can be configured from the Room Panel.
Make sure that configuration mode is set to Auto (default factory
setting). See Config mode on page 17 for details on selecting
configuration mode. With configuration mode set to Auto, the sys-tem
will detect and configure any attached sensor automatically.
Room Panel menus
The various menus of the X-AIRCONTROL Room Panel are accessed
by tapping the menu icon in the upper right corner of the screen. If the
icon is hidden, you can force it into view temporarily by tapping the
upper right corner of the screen five times. Most menu items
(marked in this Commissioning Guide) are protected by a PIN. The
PIN is 1234. If the screen saver is active, tap the screen once to
access the Home screen.
Home
Schedule menu
In the Schedule menu, you can set the required air flow and tem-
perature. Tap the Schedule button to enter the schedule menu.
Main menu 1
The system oers three dierent week schedules. In the first, each
day of the week has the same program. In the second, each day of
the week is programmed individually. In the third, work days and
home days can be programmed as two groups of days.
Week schedule selection
It is possible to define work days and home days. As default,
Monday, Tuesday, Wednesday, Thursday and Friday are defined as
work days while Saturday and Sunday are home days.
In all week schedules, days are divided into four events: morning,
work, evening and night.
Schedule example
Select the event that you want to set up. Tap the time button to
change the start time for this event. Tap the temperature button to
change the temperature setpoint. Finally, tap the air flow button
to choose the required air flow. Air flow can be set to O, Low,
High or Auto. In Auto, air flow is regulated according to sensor
values and setpoints. For details on Low and High settings, see
Air volume on page 13. Repeat this procedure for each day or
group of days.
When you have finished setting the schedule, tap the Left arrow a
couple of times to go back to the main menu.
