Vehicle heater and controls therefor

摘要: A heater for a liquid has combustion chamber, jacket the extending about chamber and burner head assembly connected to chamber. The includes housing having mounted thereon hollow interior. control module fan are in interior, being an electric motor. compressor fuel pump on operatively may include controls exercising components of prior combustion, thereby verifying operation these components. Preferably there is speed motor, such as closed loop which regulates motor accordingly output heater. backup system using lookup table event that fails. Also preferably provision monitoring flame sensor functionality by providing indicator light mirrors sensor. have selective soft start coolant operates only when required so reduce unnecessary chatter relay. also provided distinguishing true overcurrent faults from overcurrents arising voltage changes during starting vehicle engine. Reignition algorithms restart sputters caused, example, bubbles, but shut off truly cut off.
