Intended use

Das SC1000 is a device designed to control HVAC components (heating, venti-

lation, air-conditioning) for buses, e.g. roof-top air-conditioning systems, heaters

etc. It comprises always of a control panel (control device with human-to-

machine interface) which is integrated into the dashboard, and of one or more

substations, which are controlled by means of the control panel. The communi-

cation between control panel and the respective substation is done via CAN bus.

Figure 1 SC1000 Control Panel



A substation is a control device with power outputs for the control of all in the AC

unit integrated components.

Usage

Turn control panel ON/OFF

Switch on the ignition. The control panel starts

automatically.

The current software version (1.0) and the current

release appear on the display (Fig.5).

After four seconds the default screen is displayed.

(Fig.6).

Driver’s workplace functions

1. Adjust temperature

Cooling

Rotate the knob (Fig.3, No.4) counterclockwise into the blue area.

Heating:

Rotate the knob clockwise into the red area.

.

Fort the driver’s workplace no particular temperature can be

adjusted. The temperature control for the driver’s workplace not

controls the temperature, but the degree of opening the hot

water valve. This results in an uncontrolled outlet temperature. Note



Figure 7 Current Blower Speed Level

2. Adjust blower speed

Turn the knob (Fig.3, No.3) clockwise to 5 o’clock

position, to increase blower speed level.

Turn the knob counterclockwise to 7 o’clock position,

to decrease blower speed level.

The display shows the current blower speed level

(Fig.7).

3. Adjust air flow direction/ defrost function

Rotate knob clockwise into 2 o’clock position, to direct the air flow

against the wind screen.

Rotate knob (Fig.3, No.2) counterclockwise into 7 o’clock position, to

direct the air flow onto the floor.

Turn the knob into 12 o’clock position, to direct the air flow onto the

floor and against the wind screen.

The blower can be set from 20 to 100 in steps of 10.

20 is the smallest blower speed, on level 100 the blower runs

at full speed. If the knob is turned counterclockwise to its most

left position, on the display appears “OFF” and the blower is

switched off.

For operation the following conditions apply:

- If the defrost function is active the blower runs on

maximum speed.

Note



Rotate knob clockwise into 4 o’clock position, to direct the air flow

against the wind screen.

Defrost function:

Rotate knob clockwise into 5 o’clock position. The air flow is directed

against the wind screen. The water valve opens to generate heated air.



4. Toggle between fresh air and air recirculation

Press button (Fig.3, No.1), to toggle between fresh air and air

recirculation modes.
