Control Unit SG 1577 24v for Webasto TH90ST (Diesel) - 9011405A

The control unit SG 1577 24V (offshore)

Diesel T90ST

Control block.

The control unit is the main controlling element of the heater. It regulates the operation of the preheater and controls the combustion process. The control unit can be located directly on the housing of the air blower or separately from it.

The control unit for the Thermo 90S and Thermo 90ST heaters can be fixed both on the heater's supercharger (regular place) and separately from it. In the Thermo 90ST heater control unit, the back wall acts as a radiator for cooling the electronic components of the control unit, therefore, when choosing the installation location of the control unit, it is necessary to ensure thermal conditions and the gap between its back wall and the surface located behind it (at least 10 mm).
