Method For Operating a Heat Pump

Abstract

A method for operating a heat pump (1) that transfers heat to air flowing through ventilation ducts is provided. An outside temperature is acquired. If the outside temperature is higher than a limit temperature, an operating time of an electric heating register (2) of the heat pump (1) and/or an energy consumed by the heating register (2) is acquired. If the operating time exceeds a first limit value within a set period of time and/or the energy consumed by the heating register (2) in the set period of time exceeds a second limit value, a message is output.
