5.9 Calculating energy consumption, DHP-A
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 accu-
rate 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 specified outputs include the circulation pumps and also the outdoor unit’s fan.

1.90 kW 2.60 kW 3.00 kW 3.50 kW
Radiators 2.30 kW 3.05 kW 3.50 kW 4.10 kW
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: 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 sys-
tem 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.
5.10 Manual defrost, DHP-A
If DHP-A’s outdoor unit needs defrosting you can run a defrosting procedure manually from
the control computer.
To defrost manually:
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 DEFROST menu option.
3 Open the menu by pressing the right button once.
4 Press the down button to move the cursor to the MANUAL DEFROST menu option.
5 Press the right button once.
6 Press the up button once to start defrost.
7 Press the left button three times to exit the menu.
