The heat pump is heating water to the set temperature with
the compressor (automatic mode of operation). The operation
of the heat pump depends on the air temperature. If the
temperature falls below the switch-over temperature, the
heating of water by means of a boiler takes place.

If the inlet air temperature is too low or if the temperature
falls below the switch-over temperature, the heating of water
in P4 programme is performed by means of a boiler and in P5
programme with an electric heater. In this case, the
compressor is out of operation for safety reasons.
NOTE: BY PRESSING THE
KEY THE CURRENTLY SELECTER PROGRAMME IS SHOWN (this can also be
seen from the light indicators
–
see the above table). WITH EACH FURTHER PRESSING OF THE
KEY
WITHIN 8 SECONDS, WE SWITCH BETWEEN DIFFERENT AVAILABLE MODES OF OPERATION.
NOTE: BY CHOOSING THE PROGRAMME (SOURCE) WE ALSO DETERMINE THE HEAT SOURCE FOR THE
OVERHEATING OF WATER.
1. Water temperature setting:
By pressing the
or
key we see the currently set
temperature, each further pressing of the
or
key (within 10 sec) causes the
temperature value to change. Wait 5 sec and the new setting will be saved after the flashing stops.
2. Switching between different modes of operation:
Switching between modes of operation is
carried out by pressing the
key. Illuminated light indicator and a symbol shown on the display
when pressing the
key (see the above table) indicate the selected program. With each further
pressing of the
key within 8 seconds, we switch between different available modes of
operation.
3. Single thermal disinfection:
Overheating of water to over 60°C is carried out by pressing the
key (light indicator on the key is illuminated). When the overheating is finished, the light
indicator is turned off. By pressing the
key once again, the overheating process can be
interrupted early. We recommend an interval of 14 days and not more often, since the energy
consumption is about 1/3 higher than when the HP is in normal operation.
