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 human­machine 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.

1.5 Overview of modes

The SC600 contains 2 different modes – the operating mode and the
fault mode.

Operating mode:

Includes all of the
functions and notes
summarised under
point 2 except for
the fault readout

and refill mode.

The normal operat­ing display includes

all of the elements

pictured in the ex-

ample:

Mode for displaying
all of the occurring
faults and their fre­quency of occur-

rence.

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.

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 (during this pe­riod, 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 ac­tive, 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 pre­sent).

2.7.1.3 Quitting

Press button for 2 seconds

➔ Standard operating display appears (Fig. 15).
