Temp-based heating system for car engine reheater

This reference design illustrates how to design hardware for a temperature-based heating system for a vehicle that has an engine preheater installed, based on ambient temperature and a preordained engine start time. This system can also be used for other purposes, such as turning on a storage heater if the ambient temperature falls below a preordained value.
