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).
Charging level
If the minimum available mixed water volume at the selected set
temperature is insufficient, you can reduce the reheating hyster-
esis by increasing the charge level. This increases the minimum
DHW volume available. The effect equates to a virtual downward
shifting of the temperature sensor. This results in greater DHW
convenience. The efficiency of the appliance is slightly impaired.
DHW heating is started when the available mixed water volume
decreases to the percentage of maximum mixed water volume set
in the “Charge level” parameter.

The displayed mixed water volume is based on a mixed water
temperature of 40 °C. At water temperatures below 40 °C (±1 K),
the mixed water volume is not calculated or displayed.
A further start condition, which overlaps the heat-up level start
conditions, is the reduction of the temperature captured by the
sensor at the cylinder top to 6 K below the active set temperature.
Press the "Menu" key, until an "L" fol-
lowed by a number appears in the dis-
play.
You can change the value using the
"Plus" and "Minus" keys. Setting range:
30 - 100 %
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.
4.3 “Quick heat-up” key
Note
To start rapid/comfort heating with the "Rapid heat-up"
key, the start screen must be displayed.
Press the "Rapid heat-up" key for two
seconds.
The "heat pump" and "electric emergen-
cy/booster heater" symbols appear.
4.3.1 Quick/comfort heat-up
Normally, the “Rapid heat-up” key is used to enable rapid/comfort
heating, which lets you cover an unexpectedly high DHW demand
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/booster
heater will start in parallel, irrespective of the selected set tem-
perature, and will remain active until the DHW temperature in the
cylinder has reached 65 °C.
If the water temperature in the upper cylinder section rises by a
hysteresis value above the set temperature on the cylinder top
sensor, the electric emergency/booster heater is switched off.
The electric emergency/booster heater remains in standby mode
until the set temperature has been reached throughout the DHW
cylinder. A flashing “electric emergency/booster heater” symbol
indicates that the electric emergency/booster heater is in standby
mode.
The rapid/comfort heating function remains active until a temper-
ature of 65 °C has been achieved throughout the 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.
Note
To end rapid/comfort heating, press the "Rapid heat-up"
key for two seconds.
