Introduction
The CTS6000 control panel allows functions that are necessary for everyday operation to be
viewed and altered. It is thus possible to change various temperature settings, reset alarms and
start the unit outside the usual operating period. The CTS6000 control panel supplements
CTS6000 WebControl, the program in which more advanced settings are made.
A menu overview and descriptions of all alarms can be found at the end of the guide.

Control panel menus
The panel consists of a "Power" button, an "Alarm" button, four arrow buttons and a "Set" button.
The buttons have the following functions. Pressing any button for the first time activates the backlit
display. The "POWER" button is used to start/stop the system in "Weekly program" mode or to
activate "Extended operation". The "ALARM" button is used to access the alarm log. "Arrow right"
is used to enter/open a menu option. "Arrow left" is used to return. "Arrow up" is used to scroll
upwards or to increase a parameter setting. "Arrow down" is used to scroll downwards or to reduce
a parameter setting. The "SET" button is used to save a new setting.
The startup display shows current system status, see Figure 1. The main menu is opened from the
startup display using the arrow up or arrow down button, see Figure 2.
Figure 1 Panel startup display Figure 2 Menue
The startup display reappears if no button is pressed for 15 seconds.
Alarm log/event log
The alarm log is accessed by pressing the "ALARM" button, i.e. the one marked with a bell on the
bottom right of the panel. The most recent alarms/events will then be displayed, see Figure 3. It is
possible to scroll through previous alarms/events using the arrow up and down buttons.
Figure 3 Alarm log with new alarm Figure 4 Alarm log with no alarm
In the event of a new alarm, the red lamp above the alarm button will flash. Press the button to
view the alarm and then press "SET" to reset the alarm, see Figure 4. If the system has been
stopped as a result of an alarm, it will be restarted once the alarm has been reset in the alarm log if
the error that caused the alarm has been remedied.

Power button
Figure 5 Power, System in Operation
Pressing the "POWER" button opens the menu shown in Figure 5. "Stop system" is used to stop
the system or to start it in weekly program mode. If "Stop system" is selected the unit will remain
stopped and NOT follow the weekly program.
If "Start extended operation" is selected, the unit will continue to run for an additional 2 hours (the
duration can be changed via CTS6000 WebControl).
Weekly program
The control panel can be used to change the required temperature and start/stop times in the
weekly program (setpoints for fan speed or duct pressure can, however, only be changed via
CTS6000 WebControl).
The weekly program is opened from the startup display by pressing arrow up or arrow down. The
menu shown in Figure 2 will then appear. Use arrow up or arrow down to select "WEEKLY
PROGRAM"
Then press arrow right to open the weekly program, see Figure 6.
Use arrow up or arrow down to scroll through the various menu options for the day selected. As
standard, Monday is initially displayed when the weekly program is opened. Six program events
can be defined for each day of the week. Figures at the top of the display indicate the number of
events defined for the day in question. For each program event in which the unit is in operation
(Program Event: Active), it is possible to change the required settings, see Figure 6. To do so,
select the setting to be changed, press SET to change the setting, press arrow up or arrow down to
select the required value and then press SET to save the new setting.
To select another day of the week, highlight Monday, press SET, select the required day of the
week using the arrow up or arrow down buttons and then press SET again once the required day
has been highlighted.

Language selection
"LANGUAGE SELECTION" is located in the menu shown in Figure 2. The language used in the
displays can be changed under "LANGUAGE SELECTION".
Date and time
"DATE AND TIME" is located in the menu shown in Figure 2. The date and time used by the
system can be changed under "DATE AND TIME".
System information
"SYSTEM INFORMATION" is located in the menu shown in Figure 2. System status data can be
viewed under "SYSTEM INFORMATION".
Service menu
It is possible to change advanced functions, network settings and regulation parameters and to
restart the system in the "SERVICE MENU". To access the service menu, activate the control
panel by pressing arrow down. Then press and hold "SET" for approx. 10 seconds. The service
menu will then appear.
Manuel Set point menu
To enter the manual set point mode one should hold power button until the corresponding menu
appears (see Figure 7: Selecting the manual set-point mode).
After selecting the mode one is able to adjust manual mode parameters (see Figure 7: Manual
mode parameters setting). Appearance of the menu depends on the current settings of the
systems. The difference for systems with inlet only VAV fan and two 2 step fans can be seen in
Figure 8 and 9.
After the parameters are set system goes into manual mode (see Figure 10: Java GUI manual
mode).
Setting of the parameters is done in usual way with the arrows and SET keys.
