1 Introduction
1.1 Intended purpose
The SC600 is a system intended to control the HVAC components (heating, ventilation, air-
conditioning) in buses, for example roof-top air-condition systems, heating devices, etc. It con-
sists of a control panel (control device as an interface between human and machine) that is
integrated into the dashboard.
This control panel allows the driver to control the roof-top air-conditioning system that has ven-
tilation, cooling and heating functions for the roof. Additionally, this control panel can also be
used to control the heating system on the floor.
The controller for the air-conditioning systems components can operate automatically. To do
so, the bus driver simply has to set the desired temperature.
These operating instructions apply to the following air conditioning system variants:
- Air-conditioning system (AC)
- Air-conditioning system with convector (AC & convector)
- Air-conditioning system with roof heating (AC & roof heating).
The availability of individual functions (e.g. reheating) depends on the respective model - if a
function can only be used with a certain model, this will be specially indicated.

1.5 Mode overview
The SC600 system includes 2 different modes –Operating mode and Error mode.
Figure 3 - SC600 mode overview
SC600
Operating mode:
Includes all of the
functions and infor-
mation summarized
under point 2 as
well as Error mode.
The normal operat-
ing display includes
all of the elements
provided here in the
example:
Error detection
mode:
Mode to display all
errors that occurred
and their probability
of occurrence.
For more infor-
mation, see points
2.6.1 and 2.6.2.
The error display in-
cludes all of the ele-
ments provided
here in the example:

2 Use
2.1 Activation/deactivation
2.1.1 Activation
Press button
➔Sets the last configured temperature; Auto mode off
(Figure 4).
2.1.2 Deactivation
Press button
➔Display deactivated.
Press button for 2 seconds until OFF appears
➔System deactivated.
2.2 Auto mode
2.2.1 Activation
Press button if Auto mode is off
➔Mode is on - corresponding status light and function
symbol light up on the display (Figure 6).
2.2.2 Deactivation
Press button if Auto mode is on
➔Mode is off - corresponding status light and function
symbol are off (Figure 8).
Note
Auto mode can be turned on only if the motor has been
started.
Note
If Auto mode is on, the system automatically turns on Cool-
ing Mode and Heating mode (if available) as needed
(Figures 7 and 8).

2.3 Configuring the blowers manually
2.3.1 Activating the controller manually
Press button
➔Manual operation of the blower is activated - the
blower will continue running at the current speed.
➔The blower level can be manually set 3 seconds after
pressing the blower level button (the corresponding
status light blinks during this time).
2.3.2 Setting blower level
The blower can be set in level increments of 0 (blower speed = 0%) to 10 (blower speed =
100%).
Press button
➔Blower level +1 ( →).
Press button
➔Blower level -1 ( →).
Note
When Auto mode is deactivated, the air conditioning com-
pressor (after a run time of 90 seconds max.) and the heater
are turned off.
The blowers will continue to be controlled automatically if the
blower level was not manually configured.
Note
Configurations can only be applied within thepermitted limits
(e.g. vehicle motor off →blow speed max. 25%).
If the blower is set below 20%, the cooling and heating func-
tions are deactivated.

2.3.3 Deactivating the controller manually
Press button for 3 seconds
➔Manual controller deactivated.
Or:
Press button
➔Manual controller deactivated.
2.4 Fresh air/recirculating air function
Press button when fresh air valves are open
➔System activates recirculating air function for 10
minutes (corresponding function status light and dis-
play symbol light up).
➔After running for 10 minutes, the system turns off the
recirculating air function.
➔Pressing the button again within 10 minutes will de-
activate the recirculating air function and open the
fresh air valves (corresponding status light and dis-
play symbol are off).
2.5 Setting the temperature
Press button
➔Desired temperature +1 °C.
Press button
➔Desired temperature -1 °C.
Note
If the fresh are vales are closed, the corresponding status
light and the display symbol will light up (Figure 11).
Note
Temperature can be configured for 1°C intervals between 15
°C and 28 °C.
