Heat pump, solar system, photovoltaic system, ventilation device or water heater and method for controlling and / or controlling a home appliance device, in particular a heat pump

摘要

With the invention, the regulation or control of a heat pump, a solar system, a photovoltaic system, a ventilation device or a water heater is simplified and ensures trouble-free operation. With a device for controlling or containing an input field and a display, a secure operation is possible on a closed input field. Behind an input field, at least one proximity-sensitive, in particular capacitive sensor is arranged, which is connected to an evaluation electronics, in particular to an integrated circuit IC. At a touch or a strong approach of an electrically conductive object, for. As a finger, a change in the electrical state of the sensor is detected on the sensor and accordingly issued a position signal to a control and / or control electronics with a microprocessor. A method is used to detect whether a key function is desired by the operator on the input field or whether an incremental movement is to lead to an input.
