– the combustion and cooling air blower (motor with
combustion and cooling air blower)
– the heat exchanger
– the combustion pipe
– the control unit
– the glow plug/flame monitor
–the boiler
– the electrical heating elements
(not with Dual Top Evo 6)
– the housing
The following are located in the heater for control and
monitoring:
– a control unit with a temperature sensor and a speed
sensor for the cooling air blower (Hall sensor)
– a speed sensor (Hall sensor) for the heating air blower
– an air temperature sensor
– an air temperature switch
– a temperature switch for the heat exchanger
– a water temperature switch
– a water temperature sensor
The fuel supply is ensured externally via a fuel pump.
The heater is controlled with an external room temperature
sensor.
