1 Introduction
1.1 Intended purpose
The SC600 is a system for controlling HVAC components (heating, ventilation, air conditioning)
in buses as well as rooftop air conditioning units, heaters etc.
It consists of an operating element integrated into the dashboard (control device as human-
machine interface) and a rooftop air conditioning unit or floor heating. The rooftop A/C unit,
depending on the version, takes over ventilation, cooling and heating functions. In addition, air
conditioning components can be controlled completely automatically. In this case, the bus driver
only needs to set the desired temperature.

2 Operation
2.1 Switching on/off
2.1.1 Switching on
Press button
➔The temperature that was last set is now set; auto
mode on (Fig. 4)
2.1.2 Switching off
Press button
➔System is switched off
2.2 Auto mode
2.2.1 Activation
Press button in deactivated mode
➔Mode is activated - corresponding status light and
function symbol in display light up (Fig. 5)
2.2.2 Deactivation
Press button in activated auto mode
➔Mode is deactivated - corresponding status light and
function symbol are off (Fig. 8)
Note
Switching on system takes place only when the ignition is
switched on.
is activated
Note
If the auto mode is activated, the system automatically
switches on cooling mode and heating mode as re-
quired (Fig. 6 and 7).

2.3 Setting the blower manually
2.3.1 Activating the manual adjustment
Press button
➔Manual operation of the blower is activated - the
blower continues running at the current speed.
➔3 seconds after the blower level button is pressed, the
blower level can be manually adjusted (duringthis pe-
riod, the corresponding status light flashes).
2.3.2 Set blower level
The blower can be set to various levels from 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 A/C compressor and
heater will switch off (the former after a max. after-run period
of 90 secs).
The blower is automatically adjusted if the blower level is not
set automatically.
Note
Adjustment can be made within the permitted limits (e.g.,
motor off →blower speed max. 25 %)
If the blower is reduced to under 20%, cooling and heating
modes are deactivated.

2.4 Fresh air/circulation function
Press button
➔System switches on fresh air/circulation for 10
minutes (i.e., if the fresh air function is currently ac-
tive, the system switches to the circulation function
and vice versa).
➔After operating for 10 minutes, the system switches
the function that best supports reaching the desired
temperature.
➔Pressing the button again within 10 minutes leads to
switching the function and resetting to 10 minutes.
2.5 Dehumidification
Press button for 2 seconds
➔Air dehumidification activated (Fig. 11).
2.6 Setting temperature
Press button
➔Target temperature +1 °C
Press button
➔Target temperature -1 °C
Note
If the fresh air flaps are closed, the corresponding status light
lights up (Fig. 10).
Note
The temperature can be adjusted in 1 °C steps between 15
°C and 28 °C.

2.7 Faults
2.7.1 Fault readout mode
2.7.1.1 Activation
and Press buttons simultaneously for 2 seconds
➔Mode is activated; the fault code (in this case F026)
and the frequency of occurrence count (in this case
1) will be displayed (Fig. 14).
2.7.1.2 Reading out faults
➔When the code is correctly enteredScroll through the
fault codes with or .
➔Reset the counter value with (if the counter
shows "1" after the value is reset, the fault is still pre-
sent).
2.7.1.3 Quitting
Press button for 2 seconds
➔Standard operating display appears (Fig. 15).
