2 Main parts Heat pump unit Scroll compressor Stainless steel heat exchanger Circulation pumps for brine and heating systems Valves and safety equipment for cooling systems and corresponding electrical components. Water heater 80 litres Internal anti-corrosion protection with copper or stainless steel It has an anode that does not require replacing, which means that it is maintenance-free Defroster tank for outdoor unit Exchange valve The heated water either passes through to the heating system or to the water heater depending on whether heating or hot water is to be produced Auxiliary heat kw electric heating element (. kw at 0 V heat pump installation) Electric heating element control in maximum of five steps Installed on the heating system s supply pipe Covers the demand of extra energy if the heat pump s capacity is exceeded Automatically connected in the heat pump unit if operating mode AUTO is selected. Control equipment Control computer with graphic display Temperature sensors (outdoor, supply pipe, return pipe, brine, defroster, and hot water) Room sensor (option) The control equipment controls the heat pup unit s included components (compressor, circulation pumps, auxiliary heaters and exchange valve) and determines when to start and stop the pump as well as producing heat for the house or hot water.

8 Auxiliary heating and energy consumption calculation The auxiliary heater is made up of an electric heating element on the supply pipe that has three outputs, ADD.HEAT, ADD.HEAT and ADD.HEAT, and can be controlled in five steps for three phase installations. For three phase, 00V, installations: Step = ADD.HEAT = kw Step = ADD.HEAT = kw Step = ADD.HEAT + ADD.HEAT = 9 kw Step = ADD.HEAT + ADD.HEAT = kw Step = ADD.HEAT + ADD.HEAT + ADD.HEAT = kw For a single phase installation the auxiliary heater is made up of an electric heating element on the supply pipe that has two outputs, ADD.HEAT and ADD.HEAT, and can be controlled in three steps. For single phase, 0V, installations: Step = ADD.HEAT =. kw Step = ADD.HEAT = kw Step = ADD.HEAT + ADD.HEAT =. kw In the event of an alarm, the auxiliary heater engages automatically. The energy consumption calculation is difficult to specify exactly, but the average output for a normal house with normal hot water consumption in the following tables gives a relatively accurate result for each heat pump and heating system. Remember that the operating time for the heat pump installation must exceed one year before the specified values in the table are valid. The energy consumption for legionella operation is included in the hours for ADD.HEAT. The specified outputs include the circulation pumps and also the outdoor unit s fan. DHP-A Under floor heating.90 kw.0 kw.00 kw.0 kw Radiators.0 kw.0 kw.0 kw.0 kw To calculate the energy consumption: Press either the right or left button once to open the INFORMATION main menu. The cursor is in the OPERATION menu option. Press the down button to move the cursor to the OPERAT.TIME menu option. Open the menu by pressing the right button once. Note how many hours the following values have: HEAT PUMP, ADD.HEAT, ADD.HEAT and ADD.HEAT. Find the value for the average output that corresponds to your heat pump and heating system in the table above, and multiply it by the number of HEAT PUMP hours. Note the result. Multiply the number of ADD.HEAT hours by. Note the result. 7 Multiply the number of ADD.HEAT hours by. Note the result. 8 Multiply the number of ADD.HEAT hours by. Note the result. 9 Add up the multiplied values to obtain the total energy consumption. 8 VFBMA0 Technical data
