Water is heated only by generator of the device.
The temperature to which the water is being heated by the programme of quick heating
depends on the programme in which the device operates:
Basic operation programmes:
Water is heated to temperature, defined by programme
COMFORT.
Additiolan source programme:
Water is heated to temperature, set in the menu
SETTINGS OF EXTERNAL SOURCE
TEMPERATURE
(chapter 0).
8.3.3 Anti-freeze Programme
The anti-freeze programme
is activated automatically and ensures that, in the
case of a compressor defect, the system does not freeze.
The water heating programme uses heat from the selected additional source
(chapter 7.3.15.2)
NOTE
If
additional source is not selected
(chapter 7.3.15.2),
or external source is not
available
(chapter 8.2.2.2),
the programme will activate
internal electric heater.
8.3.4 PHOTOVOLTAICS
The programme photovoltaics
(PV) is a programme of device operation which
heats water with excess electrical power, obtained through a solar photovoltaic
system. The programme
activates when the device receives a PV signal via
external input
(chapter 7.3.15.3).
When the PV signal is present,
the device generator heats water to maximal work margin
of the compressor temperature
(65°C), and from there on to the set temperature of the
programme photovoltaics
(chapter 7.3.15)
water is heated by the
internal electrical heater.
If external source is mounted to the heat pump
(chapter 8.2.2.2
), the external source will be
used for heating when it is available
.
NOTE
SETTING: In the menu
EXTERNAL INPUT
(chapter 7.3.15.3)
select parameter
»PHOTOVOLTAICS (PV)«
.
8.3.5 "Bivalent mode" Programme
The power of the device at an air temperature of below 3 °C is reduced, this is why to
achieve quick water heating, the chosen additional source activates together with the
compressor
.
The bivalent mode program turns off when the air temperature is above 6 °C for 30 min.
8.3.6 "Defrost" Programme
At low air temperatures, frost forms on the evaporator which lowers the efficiency of
the device's operation. To thaw the frost, the controller activates the defrost
program.
The device's generator is activated during defrosting but it defrosts the evaporator
instead of heating water. During defrosting, heating the DHW is performed by the electric
heater.
The fan is turned off during defrosting.
NOTE
The operation of the ventilation schedule programme
(chapter 7.3.7)
is disabled
during the "Defrost" programme.
