7.3.4 Second heat generator
An existing heat generator can be used to heat the cylinder using
the integrated tube heat exchanger (1.45 m²). For this purpose, a
circulating pump can be activated by the controller. The use of a
2nd heat generator must be activated in the menu. The 2nd heat
generator is requested when the heat pump's operating limits are
exceeded, i.e. when the upper or lower air intake temperature
limit or the maximum permitted domestic hot water temperature
is exceeded. In this case, the 2nd heat generator has priority
over the heating element in the heat pump. When the 2nd heat
generator is activated, it is additionally possible to select a
switching temperature which deviates from the lower operating
limit (air temperature). If this temperature is undershot, heat
pump operation is blocked as soon as the set temperature is
reached, and the 2nd heat generator is then used.
7.3.5 Solar function
As an alternative to using a 2nd heat generator, the domestic hot
water heat pump can be operated in combination with a thermal
solar installation. The solar circulating pump (accessory) is
switched on and the heat pump switched off as soon as a solar
gain is detected. The hystereses can be set in the menu. The
circulating pump is switched off again when a solar gain is no
longer available or when a temperature limit value is exceeded,
either on the collector or in the cylinder. The solar function has
priority over heat pump operation and the heating element.
ATTENTION!
The collector sensor must be a temperature sensor with the resistance
characteristic curve of a PT1000.
7.3.6 Photovoltaic function
The function must be activated in the menu. The photovoltaic
function requires a floating NO contact from an additional
evaluation unit (e.g. an inverter). The evaluation unit contact is
wired in place of link cable "A3". The evaluation unit measures
the output that is currently available. If sufficient output is
available from the photovoltaic installation, the heat pump is
started via the NO contact and is set to the setpoint for
photovoltaic operation. The solar function has priority over the
photovoltaic function. The display shows that the heat pump is
being operated using electricity from the photovoltaic installation.

Disconnect the power supply before opening the domestic hot water heat
pump; possible fan coasting must be considered!
General
The domestic hot water heat pump is virtually maintenance-free.
Furthermore, a one-off visual inspection for possible leaks in the
water system and clogging of the condensate drain must be
carried out a few days after commissioning.
The refrigeration circuit of the heat pump does not require
maintenance.
Only use a damp cloth with a little soap solution to clean the
domestic hot water heat pump.
8.1 Water circuit / condensate
The water circuit check is limited to filters that may have been
installed on site and possible leakages. Dirty water filters should
be cleaned and, if necessary, replaced. The seal valve in the end
of the condensate hose must only be checked for contamination,
and cleaned if necessary.

8.2 Air circuit supply

Maintenance work is limited to cleaning the evaporator on a
regular basis and according to need.
Risk of injury caused by sharp-edged fins. Fins must not be deformed or
damaged!
If air filters are used, they should be regularly checked for
contamination and be cleaned and replaced if required.
