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.
