1 20 min. minimum runtime, set temperature 2
2 20 min. minimum compressor idle time
Note
An external signal must be present for at least 60 sec-
onds before the control unit responds to it. This will for
example prevent a brief burst of sunshine from triggering
a heat-up process, which due to a lack of further insola-
tion can then not be supplied with PV power generated
on site.
Changing units
…
You can select whether the temperatures and the volume details
are displayed in SI units or US units. If you select 1, the values are
displayed in degrees Celsius and litres. If you select 0, the values
are displayed in degrees Fahrenheit and gallons.
Press the "Menu" key until "SI" appears
in the display.
Using the "Plus" and "Minus" keys, set
whether the display should use SI units
(1) or US units (0).
Fault code
…
If the "Service/fault" symbol illuminates
or flashes, you can query the fault code
using the "Menu" key. This menu remains
disabled if no fault has arisen.
See chapter "Troubleshooting / Fault codes".
E fault code
…
A fault code preceded by E appears if the fault relates to the re-
frigerant circuit. Notify a qualified contractor.

"Quick heat-up" key
4.3.1 Quick/comfort heat-up
Normally, the "Rapid heat-up" key is used to enable rapid/comfort
1
heating, which lets you cover an unexpectedly high DHW demand
2
without changing any of the appliance's standard settings.
If quick/comfort heat-up is activated manually by pressing the
relevant key, the heat pump and the electric emergency/boost-
er heater will start in parallel, irrespective of the selected set
temperature, and will remain active until the DHW temperature
in the cylinder has reached 65 °C. To save energy, the electric
emergency/booster heater switches off early, as soon as a tem-
perature of 65 °C has been achieved in the upper cylinder section
(quick heat-up).
The quick/comfort heat-up function remains active until a tem-
perature of 65 °C has been achieved in the entire DHW cylinder
(comfort heating). The appliance then automatically switches back
to the previously set parameters.
Note
The "electric emergency/booster heater" and "heat pump"
symbols are displayed until the rapid/comfort heating
terminates.
During rapid/comfort heating, the "electric emergency/
booster heater" symbol is displayed until the heat pump
has heated the entire cylinder content to 65 °C and the
function terminates. The electric emergency/booster
heater already switches off when the 65 °C has been
achieved in the upper cylinder section.
Note
If the quick/comfort heat-up has been activated unin-
tentionally, you can cancel the function by lowering the
set temperature.
f Hold down the "Minus" key, until you hear a clicking
f
noise caused by the heat pump and emergency/
booster heater switching off. At the same time, the
set temperature also reverts to the value that was
selected before quick/comfort heat-up was enabled.
Press the "Quick heat-up" key.
The "heat pump" and "electric emergen-
cy/booster heater" symbols appear.
