Composition of Webasto Thermo Top Comfort+heater.
Webasto Thermo Top Start 5 consists of the following main components:
- Air blower with control unit. Disassembly of the supercharger is not allowed!
- Glow pin / flame sensor
- Temperature sensor and overheating sensor
- Circulation pump
- Dosing pump.
The principle of operation of Webasto Thermo Top Comfort+.
Starting the heater is via the signal to switch on from the control. The Thermo Top Evo can only be started by a control unit with a WBus bus or by PC diagnostics Thermo Test. When the heater is started, the supercharger, the circulation pump and the filament pin start to function. Then the metering pump is switched on. The petrol heater is started at maximum load. The diesel heater is started with a minimum load and slowly accelerating, goes to the maximum load. During the start phase, the glow pin controls the formation of the flame. After entering the maximum load mode, the filament pin performs the controlling function of the flame sensor. The heater with reaching a certain temperature (about 80°C) goes into energy-saving partial load mode. If the temperature increases further, the heater is switched off from a certain temperature (about 84°C) in the adjustment pause mode. The Gorenje process is stopped when the signal for shutdown is received, when the limit combustion temperature is reached, when the set operating time is reached, or when an error occurs.
