Abstract: A room unit for an HVAC system is disclosed including a connection means to connect the device to the HVAC system, a controller and a housing. The housing includes a mounting plate for installing a room unit on a wall of a building. The mounting plate includes a base plate with a circumferential rim projecting away perpendicularly from the base plate. The mounting plate includes at least one first protrusion projecting away from an outer surface of the rim in a direction parallel to the base plate. The housing frame includes a circumferential side wall that laterally surrounds the inside of the room unit. The side wall is configured to receive the rim of the mounting plate with positive fit. The housing frame includes at least one second protrusion projecting away from an inner surface of the side wall towards an opposite inner surface of the housing frame.

Abstract: A method for operating a drive unit of an electric bicycle is disclosed. The method includes determining a temporary actual torque curve of a driver torque generated by a muscle force of a driver of the electric bicycle. The method further includes estimating a future torque curve by extrapolating the determined actual torque curve. In addition, the method includes determining whether the estimated future torque curve falls below a predetermined first torque threshold within a predetermined first time frame. The method also includes controlled reduction of a motor torque generated by way of the drive unit when the estimated future torque curve within the first time frame falls below the first torque threshold.

Abstract: A method for controlling motor assistance provided by a motor of an electric bike is disclosed. The method includes determining a variable rate of change of a governing factor, which defines the extent to which a governing factor changes over a defined time interval The rate of change is selected such that the governing factor is decremented when a current speed is greater than a target speed, and the governing factor is incremented when the current speed is less than the target speed. The method further includes adjusting an existing governing factor based on the rate of change of the governing factor determined. The method also includes applying the governing factor calculated to a motor assistance determined for actuating the motor. A greater governing factor results in greater motor assistance than a comparatively lesser governing factor.

Abstract: A method and a drive system for adapting a drive assist by an electric drive motor of an electrically drivable bicycle. The method includes: ascertaining an instantaneous rider torque exerted by a rider of the bicycle on a drive train of the bicycle, ascertaining rider torque statistics based on a plurality of rider torques ascertained over time, ascertaining an assignment rule between the rider torque statistics and a predefined target load spectrum for the bicycle, the assignment rule approximating the rider torque statistics to the target load spectrum, establishing a motor torque corresponding to the instantaneous rider torque, based on the assignment rule, and operating the electric drive by specifying the ascertained motor torque.
