Engine heater socket with timer & temperature-controlled socket

Engine heater outlet with or without earth fault switch, see below. Without an earth fault switch, this means that the installation must be preceded by an earth fault switch. The set departure time is 24-hour repetitive with automatic summer / winter time switching and is controlled via the outdoor temperature curve to provide an efficient heating of the car. The outlet also has a function for 30 minutes turn-on time to use, for example, vacuuming the car or using electric tools in the garden.
