5.8 Calculating energy consumption, DHP-H, DHP-L, DHP-C
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 cur-
sor 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.
