Starting the System
If the solar heat is sufficient, the controller switches to
the start phase when the switch-on difference is reached.
Keep an eye on the collector temperature. If the collector
loop is filled successfully, the collector temperature chan-
ges. Flow noises in the solar circuit inlet indicate that the
filling process was successful. If after the startup time no
flowing sounds can be heard in the collector loop/flow
sub assembly, increase the start-up phase (time parame-
ter “t1”) on the controller or set the pump speed to a high-
er level.
5 Connecting the storage Insulation
●
When installed or otherwise handled, the insulation
jacket should not be colder than 60 °F / 15°C, in order
to avoid material or optical damage.
●
Close jacket insulation using the hook closure
( Figure 41). First hook into the looses position and
then successively tighten. Apply extra pressure around
the pipe connections. Completely insert cover lid in-
sulation on top, and then attack lid on top and turn, so
that the cutout is placed directly above the controller
(fig.Figure 35 page35).
●
The large round openings in the bottom area of the
insulation are required to cool the circulation pump.
The must not be closed or otherwise blocked during
operation!
●
Insulate the pipes and insert the insulation as deep as
possible into the cutouts of the hook closure aound
the pipe connections in order to minimize heat loss.
( Figure 42). The properties of the pipe insulation have
to be as specified.

6 Advice for the User
During normal operation no further settings are required.
Please note the following points:
●
Set hot water temperature
You can pre-set the desired hot water temperature on
the backup heating device. If a thermostatic mixing
valve is installed, it can be used to set the hot water
temperature.
●
Energy efficient operation
Keep the pump level as well as the minimum speed
dn
MIN
as low as possible. The backup heating tempera-
ture of the electrical immersion heater, the installed
continuous flow heater or the heating device should be
set as low as possible. Normally 104 °F to 122 °F (40 °C
to 50 °C) max. is sufficient.
●
Troubleshooting
Please contact expert personnel if the system displays
faults or defects!
●
Operation under frost conditions
The special Drain-Back technology and the use of solar
fluid guarantee protection against frost damage to at
least up to 1.4 °F (-17°C). Therefore the solar energy
system can also be operated in winter.
●
Protection against overheating
The solar energy system is absolutely safe during stag-
nation. There is no risk of damage, even if the sun
shines for longer periods without hot water being
tapped. The system switches on automatically as soon
as the solar cylinder is ready to take in more heat.
●
Shutting down the system
The system can be temporarily shut down by switching
off the electric power supply to the solar controller.The
system should be inspected (see following chapter 7).
