Conversion table for sensors
The auxiliary heater is made up of an electric heating element on the supply pipe that has three outputs, ADD.HEAT 1, ADD.HEAT 2 and ADD.HEAT 3, and can be controlled in five steps for three phase installations. For three phase, 400V, installations: • Step 1 = ADD.HEAT 1 = 3 kW • Step 2 = ADD.HEAT 2 = 6 kW • Step 3 = ADD.HEAT 1 + ADD.HEAT 2 = 9 kW • Step 4 = ADD.HEAT 2 + ADD.HEAT 3 = 12 kW • Step 5 = ADD.HEAT 1 + ADD.HEAT 2 + ADD.HEAT 3 = 15 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 1 and ADD.HEAT 2, and can be controlled in three steps. For single phase, 230V, installations: • Step 1 = ADD.HEAT 1 = 1.5 kW • Step 2 = ADD.HEAT 2 = 3 kW • Step 3 = ADD.HEAT 1 + ADD.HEAT 2 = 4.5 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 con-sumption 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 1. The specified outputs include the circulation pumps and also the outdoor unit’s fan.

The cursor is in the OPERATION menu option. 2 Press the down button to move the cursor to the OPERAT.TIME menu option. 3 Open the menu by pressing the right button once. 4 Note how many hours the following values have: HEAT PUMP, ADD.HEAT 1, ADD.HEAT 2 and ADD.HEAT 3. 5 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. 6 Multiply the number of ADD.HEAT 1 hours by 3. Note the result. 7 Multiply the number of ADD.HEAT 2 hours by 6. Note the result. 8 Multiply the number of ADD.HEAT 3 hours by 6. Note the result. 9 Add up the multiplied values to obtain the total energy consumption.
