Other burners have a contact, which keeps the burner in standby mode when the contacts are shortened (by a thermostat, for example). The burner raises it´s power again when the contact reopens.

This would be usefull when the pelletheating is combined with a solarcollector or if you need to use a oilburners control-box.
Any ideas?
