    33. Configuring the dual mode point Configuration example Central heating demand (building heat load) to DIN 4701 or EN 12831 of 7.7 kW. A DHW demand for 4 people (0.25 kW/person) and a standard outside temperature of -16 °C are assumed. The power supply utility specifies a blocking time of 2 x 2 hours. The blocking time factor Z is 1.1. Using these figures, the required heat pump output is calculated as follows: = (Q ) x Z (7.7 kW + 1.0 kW) x 1.1 = 9.6 kW 9.6 kW - 5.6 kW = 4.0 kW...

    Never remove, bypass or otherwise disable any safety or monitoring equipment. Only operate the heat pump in perfect technical condition. Any faults or damage which impact or might impact upon safety must be remedied immediately by a qualified contractor. Only replace faulty components and equipment with original Wolf spare parts. Faults are shown in plain text on the display of the control accessory – AM display module or BM-2 programming unit – and correspond to the messages listed in the following tables.
