Heating and method for controlling the heating
A heating comprising: a heat pump having an evaporator (14), a compressor (15), a condenser (25) and an expansion means (13) connected by a refrigerant piping (11, 12, 16, 27) in a cycle, at least the evaporator being arranged in an outdoor unit (10); a heating medium piping (21, 31, 34, 35, 35, 22) formed to circulate a heating medium and to flow the heating medium through the condenser exchanging heat between the refrigerant and the heating medium; an outdoor temperature sensor (19) arranged in or at the outdoor unit; and a control configured to set the flow temperature of the heating medium based on the outdoor temperature measured by the sensor and to perform a defrosting mode (B) defrosting the outdoor evaporator, wherein the control is configured to ignore the measurement result of the outdoor temperature sensor during the defrosting mode. Further, the present invention also relates to a corresponding control method.
