Abstract: The invention relates to a hot-air fan including a fan device for generating an air flow, a heating device for heating the air flow, and a control unit connected to the fan device and to the heating device. In this process, the control unit is designed to control the fan device in such a manner that, when the heating device is switched on, the fan device generates a starting air flow that is reduced to an operating air flow. The invention also relates to a method for operating the hot-air fan, including the steps of switching on the heating device and generating a starting air flow that is reduced to an operating air flow.

Abstract: A hot air blower has at least one fan impeller and at least one electrical heating device. The hot air blower is designed to interact with a coding unit provided with coding. The hot air blower is releasably connected to the coding unit. The coding unit is designed to predefine at least one of heating power and hot air temperature of a heating device in the hot air blower on the basis of the coding.

Abstract: A device for preventing power devices from operating unattended. The device includes a terminal for connection to power, a power device having an ON/OFF switch for turning the power device either ON or OFF, and a safety circuit located between the terminal and the ON/OFF switch. The safety circuit detects the state of the ON/OFF switch to determine whether or not to allow power to be provided from the terminal to the ON/OFF switch. If the ON/OFF switch is in the OFF position when power is applied to the terminal, the safety circuit allows power to be provided to the ON/OFF switch. If the ON/OFF switch is switched to the ON position when power is applied to the terminal, the safety circuit prevents power from being provided to the ON/OFF switch until the ON/OFF switch is first turned OFF.
