Auxiliary heating and energy consumption calculation
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 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
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
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 legion operation is included in the hours for ADD.HEAT 1.
The indicated outputs include circulation pumps.

To calculate the energy consumption:
1 Press either the right or left button once to open the INFORMATION main menu. 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: HEATPUMP, ADD.HEAT 1, and ADD.HEAT 2.
5 In the tables above find the value for the average output that corresponds to your heat pump and heating system, 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 Add up the multiplied values to obtain the total energy consumption.
