This control unit must be disconnected from the mains before any installation
and wiring work is carried out.
This device may only be opened, connected and commissioned by trained
personnel. In so doing, the relevant safety regulations, especially VDE 0100
must be adhered to.
•
Prior to any installation or wiring
work on the electric motors, always
fully disconnect the device from the
operating voltage and ensure that the
mains supply cannot be reactivated.
Never mix up the connections for the
protective safety low voltage area
(sensor, flow meter) with the 230 V
connections.
This
could
result
in
damage and hazardous voltages to the
device itself and to the attached sensors
and devices.
•
Solar thermal systems can become very
hot. There is a risk of being burnt. Take
care when installing the temperature
sensor.
•
Install the BDC 102 in such a way that
no excessive operating temperatures
(>50°C) result, e.g. as a result of heat
sources.
•
BDC 102 is not protected against
splashing and dripping. You should
therefore install it in a dry location.
•
If there are signs of damage to the
control unit, cables or attached pumps
and valves, the systems must not be
operated.
•
Check whether the materials used for
the piping, thermal insulation, pumps
and
valves
are
suitable for the
temperatures that will occur in the
system.
If you have any questions concerning your solar thermal system or your control unit, please
contact your installer or supplier for advice.
