- Solar control unit:
The control unit allows the circulator to be stopped if the temperatures at the solar
collector exceed the set limit T (measured by the PT 1000 probe). It allows the
circulator to be stopped if temperatures in the storage tank is higher than 80 - 90°C
(measured by the NTC probe in the boiler). It also allows ANTIFREEZE to circulate
at a settable minimum T <T (measured in the pipework via an NTC probe). It is
recommended to use Thermics Energie control units as they are tested and pre-
set for the system to operate correctly and to optimize the yield of Thermics Energie
solar field.
- Lightning:
It is mandatory to ground the system. The solar collector must have potential
balancing for protection against lightning, in compliance with the regulations in
force in the country of installation. The frame of the solar collector frame and the
ground should be equipotentially bonded. A very effective earth conductor
connection should be provided with a copper cable having a minimum section of
10 mm. If there is already a lightning protection system, connect the frame to the
existing equipotential conduit. The connection must also intercept the delivery and
return pipes in addition to the frame. For very large solar systems, consider a
connection to the equipotential conduit for every 200 sq. m.
s. Faulty or damaged evacuated tube replacement
Warning For systems with solar fields of >15m2 or for large solar fields, it is
necessary to provide > a system for the disposal of thermal energy that is not
utilized by the user (dry cooler, static dissipaters etc.). Avoid thermal shocks to
the solar collectors. Warning Danger of injury due to damaged vacuum tubes.
Caution Evacuated tubes must not be replaced with the circuit at high temperature
or when stagnant or when in the sun. Before replacing a tube, the temperature of
the battery in which the panel with the tube to be replaced is located, should be
lowered, for example by covering it.
Danger Burns due to hot components (system in operation).
Note During the replacement of damaged or defective tubes, the solar system can
remain in operation and without having to discharge the circuit even if the battery
is kept at a boiling or lukewarm temperature.
To remove and replace the tubes from the collector, proceed as follows:
Unscrew the end caps of the frame without attachments.
