1. Introduction
1.1 Intended Use
The SC1000 is a device designed to control HVAC components (heating, ventilation, air-condi-
tioning) 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 communication between control panel and the respective substation is done via CAN bus.

Figure 2 - SC1000 Control Panel HVAC Version
A substation is a control device with power outputs for the control of all the components inte-
grated in the AC unit.

2. Usage
2.1 Turn ON
➔Switch on the ignition.
➔The control panel starts automatically.
➔The current software version (1.0) and the current re-
lease appear on the display (Fig.7).
➔After four seconds the default screen is displayed. (Fig.8).
2.2 Turn OFF
➔Switch off the ignition.
➔The system powers down.
2.3 Driver’s workplace functions
2.3.1 Adjust Temperature
2.3.1.1 Cooling (if the roof-top air-conditioning unit is in cooling mode only)
Rotate the knob (Fig.5, No.4) counterclockwise into the blue area.
Note
Neither the current temperature, nor the setpoint
temperature for the driver's workplace, are shown in
the display. The temperature can be adjusted in nine
steps. At level 0 (the knob is in the left-most position)
there is no regulation of temperature, at level nine
(the knob is in the right-most position) the heater
operates at maximum power.
If a climate evaporator is installed in the front box, the
cooling is always on at the driver's seat whenever the
compressor is on. In order to achieve a warmer tempera-
ture, the driver must heat it up to counteract the cooling.
